ABSTRACT: Jump-like deformation of metallic mono-crystals at
constant loads is fully discussed in References 1 - 3.
The results of previous investigations have shown that in
order to obtain more accurate data for the investigation
of the effects of evalanche shear, the sensitivity of
the channel 1 and -the frequency pass bands of the channel
R should be increased. In the present article the authors
describe a method of continuous registration of small
sample deformations with an accuracy of dolwn to 56R and
frequency pass band of the channel 0 - 20OOc/s, and of
simultaneous small changes 8of the sample resistance with
accuracy do~;m to 0.5 x 10- ohm and frequency band from
a fraction of a cycle to 1000cls. A schematic diagram
of the mechanical part of the apparatus is Saven in

(FiE;. 2) uses a photo cell type StSV-3 (CI:XB-3) placed
with its light source in the chamber 1. The channel for
the registration of jump-like changes of the electrical
resistance (channel R, Fig. 3) consists of a sensitive AC
amplifier with a frequency band from 4-20OOc/s and with
the level of fluctuation 'noise as referred to the input,
of the order of a few thousandths ofwV. The experiments
have shown that the instrument has a high degree of sensi-
tivity and stability. A schematic diagram of the mechani-
cal installation, the basic circuLt diagram of channel 1,
the basic circuit diagram of the channel R and a photograph
of small jump-like deformations are given. There are 4

ABSTRACT: The investi-ations of the "elementary" displacements of about
500 - 2000 1 are the most interesting ones, which occur in a
gliding zone. For this purpose the ability of the channel to
record deformations was raised to 50 L The experiments were
carried out with cadmium monocrystals of a diameter of Ot75 mm,
and with zinc monocrystals of 0,5 mm of diameter. These crystals
were 15 - 20 mm long and the angle between the hexac.-onal axis
0
and the direction of extension was 30 . The extension experi-!
ments were carried out at room temperature and led to an ex-
tension of 3 - 5 In connection vrith slight and slow deforma-
tions like these the'total increase of the resistance was not
remarkably higher than the geometrically conditioned increase.

decrease up to 30 ~-' 0.8 aompared with the geometrically condi-
tioned values with 01 > 1000 L This corresponds to a dis-
placement by about 500 interatomic distances in the direction
of the gliding (here R denotes the rheostat, 1 - the exten-
sion and r 0 denotes the resistance of the unit of length of the
not deformed sample.)p re-establishment of the order and a de-
crease of the defects of the structure within the area of the
gliding corresponds to the large cracks which exceed a certain
critical amount. It is especially referred to 'the paired cracks.
Finally the authors give an explanation for the development of
the phenomena here descri bed. Despite the short duration of the
cracks the importance of the vacancies in connection with the
increasing resistance of the hardened metal and its relation
to the dislocation mechanism of the deformation has to be con-
sidered. There are 2 figures and 6 references, 2 of which are

PERIODICAL: Doklady AN SSSR, 1957, Vol- 116, Nr 5, PP- 769-771 (USSR)
ABSTRACT: At first the authors shortly report on respective literature.
In the present works the monocrystals. of zinc, tin, cadmium
and lead (degree of purity 99.99 %, diameter 0.5 mm,
length about 10 mm) were investigated. As surface-active
substance served mercury which was applied in form of a
thin coating by means of immerging the sample into an
Hg2(NO 3)2-solut ion. The mercury covered the monocrystal.
with an equal film of about 0.1 p thickness and was rapidly
saturated with the metal to be investigated. The investi-
gation of the strength properties of the amalgamated mono-
crystals in their expansion with constant velocity showed
that the strength of the zinc- and tin- monocrystals
Card 1/3 covered with mercury was a few times less than the strength

of the non-amalgamated monocrystals. Such an abrupt decrease
of strength is obviously connected with the important
decrease of surface tension at the metal/mercury boundary
as well as with the decrease of the production operation
of a new surface at the crack. The investigation of axial
ground sections of amalgamated zinc-monocrystals according
to their deformation showed the following: The cracks can
develop on the surface as well as in the interior of the
monocrystal, which can be seen in observing the axial ground
sections. The develooment of the cracks in the inner part
can be connected with a noticeable diffusion of mercury
into zinc (atroom temperature) with subsequent decrease of
the surface tension on the developing inner separation
surfaces. The rise of temperature up to 1600 C annihilates
the above-mentioned phenomena of catastrophic brittleness
with the zinc-monocrystals investigated and reconstitutes
completely the plasticity and the strength. Also the
decrease of the deformation velocity causes phenomena
which are similar to those developing with the rise of
Card 2/3 temperature. The strength of the body decreases with the

ABSTRACTs In a previous work the followina was shownt The jumps of
deformation of 0,5 to 20 U which usually can be observed in
the case of exDansion of a zinc-crystal, have a very compli-
cated structure and are the sum of a series of elementary
jumps, which form in the various cross sections of the cry-
stal. The investi.~ation of Vic elementary shifts made it ne-
cessary to diminioli thc inertia of the apparatus considerably
and to increp-sc its sensitivity to 50 R. The mono-crystals
with the diameter of 0,4 to 0,8 mm, which were of very pure
(99,99 zinc, cadmium, tin, 1-e-ad and aluminum, were stretch-
ed during constant stress and at room te.-aperature, whereby
Card 1/3 the stress was a bit higher than the stretching-strain limit.

On the Nature of the Unhomogeneous Plastic Deformation of Mietal hiono-Crystals
In all the cases of the test-pieces (save aluminum) together
with the deformation also the change of theelectric resistance
of the test-piece was registered. In the c ase of stretching
zinc, cadmium and tin many small jumps of 150 to '00 1 on to
2 000 a with a duration of 1 - 3 to 30 microseconds were re-
ig7istered. Jumps until 10 000 - 15 000 R were found rather
seldom, and if they were found, they were usually of several
small jum s. Also considerably less expressed jumps of 1 000
to 5 000 ~ were observed. By careful microscopic examination
of the deformed crystals was found out that those jumps of
deformation result on shearing and not on twin-formation. The
number of jumps, which can be observed, increases with the
decrease of their size klat least on to 250 - 300 R). Obviously
there is no minimum size of the jumps, but a superior limit
of the elementary shift. In the case of mono-crystals of alu-
minum and of lead a clearly marked formation of jumps was not
observed. The results which were found out here prove the re-
sults on lar.1-e jumps. The discontinuity of the flow and the
quick jumps are to be regarded as a com::,,on feature which is
produced by the nature of dislocation of the plastic defor-

ABSTRACT: First the author shortly reports on previous works dealing with
the same subject. According to the theory of Mott the local
concentrations of the stresses in a crystal are caused by
dislocation accumulations which are formed in front of various
obstacles in the glide plane. In the case of existente of a
shear stress 'yand of n dislocations in the accumulation the
force reaches the value n3b per unit, oflength, whereby b
denotes unit translation. In reality n is limited by two
factors: 1) If the leading dislocation is well fixed the dis-
locations will accumulate at the distance L in front of the
obstacle -

Here e-4o denotes the Poisson coefficient, G the shear modulus,
and L denotes the diameter for smaller ( ~4 1 mm) monocrystals
or the grain size for the polycrystals, resp. 2) The obstacle
is characterized by the potential barrier U(x), its height
Umax determining the activation energy in the overcoming of the
obstacle at ;Ir - 0. The quantity Igrad U(x)j max /b2 = Ti(o)
represents the local stress n 3' necessary for rupturing at
T = OOK. The author then introduces the quantity S = N/n
which is important as criterion for the deformation capacity
of a crystal. Here applies

developing microfissure. Explicit terms for this criterion
are given and discussed. A term is given for the critical

A Criterion of Crystal Deformation Capacity and Adsorption Eff-ct---
In the case of weak (organic) adsorption active agents (which
cannot render it brittle, but plastic under certain
conditions) a slight modification of a itself cannot displace
considerably the branches of the criterion S. If, however, in
the case of the given deformation conditions the interactions
b"ween the dislocations and the free surface of the crystal
play an important r8le, even a slight decrease of a can
considerably increase the second branch S2 of the criterion.
The corresponding energy barrier U max - ba t' 0,5 eV is due
to the occurrence of an inter stage in the transition of a
dislocation to the surface and is considerably steep. The
,:-enerality of the scheme suggested here was limited by
various conditions which then can also be omitted.

TITLE: Concerning the Change in Mechanical Properties,
Structure, and Electrical Conductivity of Metallic
Single Crystals Under the Influence of a Strongly
Active Adsorptive Medium
PERIODICAL: Kristallografiya, 1959, voi 4, Nr 6, op 887-897 (USSR)
ABSTRACT: This article deals with changes in the mechanical
strength and deformation characteristics of solids
due to vanishin-ly small 'amounts of adsorbed surface-
active matter, Increased plasticityc-nd flow rates,
lowered yield lim.1ts of metals covered by organic
compounds which are lightly surface-active, and
increased brittleness of high-melting metals coated
by low-melting metal melt such as of Zn and Cd coated
by Hg or Sn. Possible explanations for these phe-
nomena are cited from the works of Academician P. A.
Rebinder and his school (Dokl. Acad. Sci. USSR, ill,
Card 1/6 1284, 1956; and others). The authors studied the

TITLE: Regularities in the Brittle Practure of Pure and Alloyed Single Crystals
of Zinc
PERIODICAL: inzhenerno-fizi,:heskiy zhurnal, 1959, Nr -(, PP 45 - 52 (US5R)
ABSTRACT, The authors Studied regularities in the fracture of pure and alloyed
single crystals of zinc along the cleavage plane (01001). Pure crystals
were taken of 3 kinds: containing 99.999% of elemental zinc, containing
99.99% of it and commercial zinc; those of alloyed specimens contained
0.2 and 0.5% of cadmium. Experiments were carried out in two versions:
in the absence of an active absorption medium at a temperature of -1960C
and with a thin mercury film of about 5~,thick. applied to the specimen,
at room temperature. Crystals were produced by the zonal crystalliza-
tion method and were 0-54 to O.Q1 mm in diameter and about 10 mm long.
The fracture ol .-ia~; performed on the Polyany device at a con-
stant stretching rate of !U- to 15% per minute, The aul-hors formulated a
11condition of the c-onstancy of the product of normal by sieari-rLa, stresses",
which is expressed by Formula 1 p, , 'Cc = const = K2. By analyzing a
Card 1/3 considerable amount of experimerr:al data the authorz have established that

Regularities in the Brittle Fracture of Pure and Alloyed Single Crystals of Zinc
this condition is fulfilled within a wide range of orientations of
single crystals for both pure and alloyed specimens. As the quantity
of the admixture increases, the value of K also increases. The authors
explain this by a hypothesis on the origination of heterogeneities in
the shearing process and occurrence of plastic deformation during a
phase immediately preceding fracture. The value of K for amalgamated
specimens is twice as low compared to - non-amalgamated
ones, both for pure and alloyed crystals. This is explained by the
lowering of the surface energy of zinc in the presence of mercury.
The condition formulated by the authors agrees well also with the ex-
perimental data of the other investigators in this field, such as
Deruyttere and Greenoqgh ZRef g, and is consistent with the theory

ABSTRACT: In the papers (RL-fs 1-4) the authors investigated the rupture
of pure zinc single crystals along the cleavage face (0001)
and found that the product of normal and cleavage tensions is
2
constant - pctc = const = K . The results are given for tech-
nical zinc and for zinc alloyed up to 0.5 % with Cd and com-
pared with the results obtained for pure zinc (Table 1).
Figure 1 shows the values of rupture tension for pure zinc at
-1960 C and various angles between crystal axis and face
(0001) as well as the effect of a mercury film upon the
strength at +200 C. Table 1 shows that X increases with in-
creasing amount of additions. Figure 2 shows the values of

zinc single crystal in dependence on the crystallographic
shear a. The characteristic break of the deformation curve
at a0 (flow limit) as well as the increase in strength for
a < a., connected with the latter are due to the increase of
the incomplete shears (dislocation accumulation). ao de-
creases with increasing amount of alloy components. Table I
gives the degree of inhomogenefty f = ao/al (ao' refers to pure
0
zinc). As shown by figures 3 and 4, the experimental results
are in good agreement with those obtained by A. Deruyttiere
and G. B. Greenough (Ref 5). Pcr0 = K2 holds for both amalgam-
ated and not amalgamated zinc single crystals of varying
purity. The values for K are reduced by 50 O,~6' as a result of
the reduction of the free surface activity a. The authors
thank V. I. Likhtman for his advice. There are 4 figures,
1 table, and 13 references, 12 of which are Soviet.

ABSTRACT: This article deals with 'he inflaence exercised by a thin li-
quid gallium film upon the mechanical and structural properties
of the single crystals of tin and upon their electrical con-
ductivity. Dif-ferently oriented single crystals of tin (degree
of purity 9.0.999 c,*/., diameter 0.5 - 1 mm, length 10-25 mM) were
bred by the method of zone crystallization. The liquid me-
tallic gallium was mechanically applied to the surface of
the samples in a quantity of from tenths of a milligram to
5-10 mg. As in 1he case of Zn-Hg and other pairs mentioned al-
ready earlier, plasticit.-i- and strength of the single crystals
of tin decrease abruptly as soon as the gallium has been

latter on the single crystal of tin, this phenomenon extends
throuzhout the entire crystal volume. In the case of samples
oriented in such a manner that their original resistance is only
small (i.e. at large angles ~ between the tEt-ragonal
0 [00~
axis and the sample axis), resistance increases In the course
of time, while it gradually drops after the coating of samples
with high original resistance (if the tetragonal axis is near
the sample axis). Gallium for gallium saturated with tin)
is a strong adsorbe-,,t for tin. During elongation in liquid
nit.ro-en ~he strencrth. of samples coated with gallium really
increases as-compared to single crystals without coating. The

TITLE: Origin and Development of Cracks in Deformed Crystals~
PERIODICAL: Doklady Akademii nauk SSSR9 1960, Vol. 133, No. 1,
pp. 71-73
TEXT: By way of introduction, the authors subdivide the cracking of a
crystal on stretching into two stages depending on the course of deforma-
tion. In the stage A there occurs a slow formation and a gradual growth of
the cracks at sites with high tension; in the stage B the crack quickly ex-
tends over the entire cross section of the crystal. The authors discuss the
basic role of shear in stage Ag and explain the origin of microcracks in
this stage by the unification of dislocations and the formation of hollow
nuclei. The mechanism of the development of cracks is closely examined, and
V. N. Rozhanskiy (Ref. 7) is mentioned in a discussion of the position of
the cracks in the lattice. The most probable arrangement is regarded to be
the serial arrangement of dislocations in a lattice plane, which develop to

a crack on further deformation. Formula (1) is given for the length c of a
crack, and formula (2) for the normal tension, From these formulas the
authors derive the condition for the constancy of the product from normal
tension and shear stress; this constancy is well proven by experiments. The
authors tested the independence of expression (1) of expression (2). For
this purpose they studied the development of cracks in amalgamated zinc
single crystals. Microscopic analyses revealed inner cracks in the crystal
plane (0001) of all samples. Relation (1) and (2) by Griffith were tested
experimentally, and a few relative results are given. The authors state
finally that the results obtained by them prove the universal character of
the scheme worked out by them for the analysis of a crack development.4

TEXT: In the introduction, the authors refer to some of their own
previous papers (Refs, 1 and 2). There, it had been clearly established
that in the rupture of amalgamated single zinc crystals a spread of
rupture stresses occurs along the basic plane (0001), If, for a given
angle L between the plane (0001) and the sample axis, Pmin Q.) and
PmaxQo) are the minimum and maximum rupture stresses for the angle
then the relative quantity (Pmax - Pmin)/P max strongly increases with 0
increasing Zo, For Z.) 50', this quantity remains below 10%. for L< 30
it attains a value of more than 25%. To clarify these relations, the

authors carried out microscopic investigations of the basic planes (0001)
of the fragments obtained in the rupture of many amalgamated single zinc
crystals., The diameter of the single crystals L0was about 1 mm, 10 was
between 20 and 700. Many steps were found (Fig. 1) in the surfaces of
fracture which were caused by cracks on the transition from one (0001)
plane into the other. Thorough investigations showed that the main steps
appear in the places of origin of rupture cracks. In previous papers
(Refs' 3 and 4). the authors gave a detailed theory of the origin of
cracks, and here they q-uote formula ~1) obtained here:

differently oriented samples. It appears that (1) is fulfilled in a wide
range of orientation with an error of about 10%. From the results

TITLE: Mechanism of coarse destruction of metallic crystals
PERIODICAL: Fizika tverdogo tela, v. 3, no. 3, 1961, q02-910
TEXT: Studies conducted by the authirs in their laboratory have shown that
the mechanical properties of metals can be strongly influenced by placing
them in highly adsorbing media (fusion of fusible metals). Such a treatment
results in a considerable decrease in plasticity and strength. In the
papers of Academician F. A. Rebinder et al. on the effect produced by adsorp-
tion from the ambient medium upon the mechanical Droperties of Solids, thesq
effects have been ascribed to the considerable decrease in free surface
energy on the boundary between the deformed metal and its saturated solution
in the other liquid metal. This effect of the metal melt occurs immediately.
Experiments have shown that the rule governing the deformation and coarse
destruction of metals is not altered by the presence of the liquid metalt
The study of the mechanism of coarse destruction of metals is, however,
considerably facilitated by the use of active metal melts. The present
Card 1/4

papi~r includes a detailed discussion of experimental data relating to this
subject. The data were obtained at room temperature for amalgamated single
crystals of zinc.. Theoretical investigations have shown that the destruc-
tion (rupture on elongation) of single crystals of metals can be divided
into two stages: Stage A: More or less slow formation and extension of
"embryonic" cracks .--it points of elevated concentration of stresses, caused
by inhomogeneities ef plastic deformation. In this stage, the shear stress
T plays the most significant role. The growth of the cracks is accompanied
by the occurrence of new dislocations. Stage B: Rapid extension of an
unbalanced crack over the entire cross section ~Tf the crystal. This process
is predominated by the normal stress p. The critical relation between nor-
mal stress and shear stress is given by pcTc = I 2Gd/L, where y is a dimen-
sionless coefficient which differs only slightly from 1; G is the shear
modulus, L the cross section of the single crystal, and a the specific free
surface'energy. Furthermore, the relations
c r 2L2 ~~ (1) and pc = a(EG/c )1/2 a I (G C/c 1/2 (2) hold;
E_a = Go max
max 2~r, max
c is the length of the crack, E the elastic modulus, and P a dimensionless

coefficient of the order of unity. The two last-mentioned relations which
characterize A and B, respectively,-mre experimentally verified independent-
ly of each other. This was done by a study of the formation of cracks on
an increase in D and T. The specimens (amalgamated single crystals of zinc)
had a purity of 99.9~%, a diameter of 1 mm, a length of 10 mm, and showed
different angles of inclination of the basal planes toward the axis of the
specimens. The rate of elongation was constant and amounted to 12'~f./min.
The stresses were determined from the relations
P sin cos)(~ PC = P sin)(osin where P is the tensile stress referred
0 ~O 0 0
to the initial cross section, and is the angle of inclinaticii of the basal
plane toward the axis of the specimenfor a given deformation E. The valid-
ity of the function c max (x) was proved by a series of specimens with
210, and specimens withY 0 varying from 106 to 670 showed the correct-
ness u: the relation (2) by 6riffith. A study of cracks of destruyed
ppeci;-,.~ns has shown that the predominant role in the formation of destruc-
,tive cracks is presumably played by ang-ular or screw dislocations,

PERIODICAL: Doklady Akademii nauk SSSR, v, 136, no. 6, i96,, 1392-13,05)
TEXT: The authors deal with tile problem of changing the mechanical
properties of metals by the action of surface--active metals. The present
paper reports an the action of small mercury drcps on cracking'in a bent
zinc plate. Industrial zinc of the thickness 6 = 0.8-3 mm and' the width
a of up to 50 cm was bent by a force F, as Is shown in Fig. 1. In the
U was only about 7-8 kg/=2 (tensile
place of Hg application, 'he stress om
strength of Zn about 18 kg/MM2). in the absence of Hg, no considerable
residual deformations occurred after 10 min; at a higher load, the zinc,
could be bent at right angles. If, however, at a pm of a-bout '7 kg/mm2,
an Hg drop (mass m about 0.2-.40 mg) was applied to the zinc surface

polished by etching, a crack formed which, in A -_-,hcrt time (1-2 sa:~),
adsorbed the entire Hg, and rapidly extended perpendicular to pm. The
rate of extension decreased gradually, and was already -.-ery lc,-.,v after
5-10 min. The crack extended ovar the greater part -:f -.,.5 length thrcugh
the entire thickness 6 of the plate. The final lengtl, L of the crack
depended on the quantity of Hg. On the basis of conc--eEts of the migration
of Hg along the cracked surface and the diffusion of Hg into the cracked
surface, the authors derived for the length L:
L - A6-2/3m 2/3 (A = const). This equation was confirmed expcrimentally.
Cracking showed three stages. At the first stage, 'he rate of crackil-,g
is constant and independent of m, the mass of the Hg drop. H- is
adsorbed, and distributed over the crack, With increasing volume of the
crack, the Hg is no longer sufficient to fill. it. This is the beginning
of the second stage. Hg is distributed as a liquid phase only on the
crack surface. The Hg migrates to the place of destrucrion, and diffuses
into the crack surface at the same time. At the third stage, no -more
liquid Hg is present. The slow growth of the slit tahes i) lace through
migration, the Hg adsorbed on the slit -wall being redistributed.

According to the authors' opinion, a detailed analysis of migration and
diffusion, and the reduction in strength of metals under the action of
surface-active melts, can be studied by means of such experiments.
Furthermore,' the kinetics and migration of adsorptive atoms will be
studied. There are 4 figures and 4 Soviet-bloc references.

TITLE: Effect'of the microrelief on the rules governing the
propagation of liquid metal on a solid metal surface
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 146, no. 3, 1962, 638-641
TEXT: 'Jhen the propagation of mercury on a backing of crystalline zinc
freed from the oxide film by N.H was being studied, two types of propaga-
3
tion dependent on the microrelief were observed for the first time:
wetting and diffusion. These processes diffet essentially in their
mechanisms. On a smooth zinc surface the mercury forms as a drop with the
edee of contact 'L$ - 70. A dull -spot propagates from the periphery of the
drop, showing the time dependence r-tO-5 which is characteristic of
diffusion processes. The mass m of the drop does not affect the propaga-
tion velocity. For smooth zinc lamellas dipped obliquely into mercury,
this velocity does not depend on the angle of inclination. The rate of

diffusion increases with rising temperature owing to the temperature
dependence of the diffusion coefficient: Dprf -'exp(-U/kT), where
U - activation energy. On zinc surfaces roughened by etching with HNO 3
the mercury drop forms no constant edge of contact, and the spot
propagates by the movement of the liquid Hg layer. The rise of Hg on
rough surfaces depends on the angle of inclination of the surface and on
the mass of the drop. r - (6m6a/n-%6)1/4t i /f4=Atl/4 holds, which is in
good agreement with the experimentally determined dependence r rV t0-3.
A a - a32 - (512 - 631' where a121 (320 a 31 are the specific free surface
energies of the liquid at its interface with the medium, the solid at its
interface with the medium and the solid at its interface with the liquid,
respectively; TL - viscosity of Hg, 6 - density of Hg. If the smooth
surface has a groove in the form of an isosceles triangle with the
interior angle a, the fig will flow along the groove if ~< (180 - a)/2.
Examination of the profilograms of differently roughened surfaces confirmed
that wetting occurred instead of diffusion if arv1600. Conclusions: On
an ideally smooth surface, and under the action of surface tension alone,
a thin liquid layer will not spread as the migration of liquid.atoms

If a surface has no microrelief, no wetting will occur. Similar studies

ABSTRACT:- The authors review previously published material on breaking of non-

Idefects in glass.is studied by cr eating artificial microscopic defectsIin the sur-
Iface layer', lowering the.resistance of the samples tested. Indentations were made
in the center of ~5x 25 mm samples 1.3-1.4 mm thick and the resista nee of thesam-7
ples was measured. When indentations are made at various distances from tfie centeri
the resistance of the sample grows with an increase in d1stance. The nature of dis_l
tortion is studied microscopically. Two methcds are described to~separate the ef-

and stresses. The use.of the simple method of Imposing artificial indentations can-
be ed to evaluate real defects in glass and help to determine equivalent charac-

both accompanied and unaccompanied by annealing, and also.samples inj-,.
which no other flaws existed other than those producedartifically,
have shown that real defects existing in glass and determining its.
resi-vtance to failure are equivalent to indentations made artift
cially by a diamond, within a definite load interval. The results
make it possible therefore not only to estimati~ the effect of real
defects of the glass structure and express them in quantitative man-
ner, but also to investigate the role that local concentration of
strains and stresses can play in processes that lead to the failure
of glass. The results haveja ilearing on efforts made by others to
produce high-strength glass.0 .-'The,authors thank F. F. VitmanJLnd
