ABSTRACI- This investigation was undertaken to resolve the present contro.'.~ersy
concerning the nature of the cbmpounds formed in the solid state diffusion of iron
into aluminum. Electron and x-ray diffraction spectra of bimetallic specimens con-
sisting of Armco A iron and high purity aluminum AVOOO were investigated. The alumi-
num coating of the specimens was of sufficient thickness (2 and 6 14 to yield a
characteristic aluminum x-ray pattern, as suggested by TY1. M. Umanskiy and M. P.
Shaskol'skaya (zhTF9 19641 VYP- 11, t- 14, str. 1283--1290). The experimental results

are presented in graphs and tables (Bee pig. 1), It was found that the solid stete
diffusion of iron in-to.aluminum begins at 350C and gives rise to the formation of the
compotmd FeAl . At higher temperatures (up to 400C) Fe2Al is formed, and at 650C'th6

ABSTRACT: There is a discrepancy between two theories of this mechanism. Thus, Pfeil.
(Iron and Steel Inst., 1929, 119, 501) established that the dominant factor in the
oxidation of iron is the diffusion of Fe ions through the scale, whereas Davies et
al. (J. Metals, 1951, 3, 10t 889) and Himel et al. (J. Metals, 1953, 5, 6, 827)
believe tha oxygen diffusion accounts two-thirds for the formation of Fe304 layers
and entirely for the formation of Fe 0 3 layer and consider the diffusion of cations
as the dominant factor in the oxidation of iron. To clear up this discrepancy, the
authors performed a simple experiment: specimens of armco iron were oxidized in air
~at 1000*C until a Fe203layer several microns thick ha4 formed. After this, a plati-
num tag (wire of 100-p diameter) was placed on the surface of the specimen without
removing it from the furnace and the oxidation was continued for several hours.

alloys

TOPIC TAGS: critical pointj superconducting alloy, lattice defect, grain structure,

ABSTRACT: The effect of a homogenization anneal on the critical current density of
Nb-46% Ti and alloy-2 was studied. The purpose of this heat treatment was to elimi-
nate intercrystalline liquation which exists in the as-cast alloys. It is known that
the Lorentz force can cause a creep of magnetic current that may result in the loss
of superconductivity. Different. types of metallic defects Unhomogeneities, disloca-
tions, internal stresses, etc.) may act as stabilizers against the creep. For the ex-,
periments, 40-gram ingots were malted in a radiant are furnace with tungsten elec-
trodes in a purified helium atmosphere and homogenized in a vacuum furnace at 15000C.
The homogenized ingots were cold reduced into 0.25 Mm diameter samples. All samples
1/2 UDC: 537.312.62
1 had similar cold reductions. Critical current densities were measured in a trans-
verse magnetic field of 16 kilooersted at 4.20K. The critical current density was
given as a function of ingot homogenization time which ranged from 1 to 5 hours. In
both alloys, the critical currant density was lowered by homogenization. The criti-
cal current density for Nb-46% Ti 6ecreased linearly from about 1.8.104 a/CM2 in the
as-cast condition to about 104 a/cm2 after 5 hours of ingot homogenization. Alloy-2
dropped sharply from 2*104 a/cm? to about 104 a/cm2 after 1 hour of ingot homogeniza-
tion, and remained constant thereafter. All of the samples had a similar disloca-
tion density of 1011-1012 cm-2, characteristic of severely deformed metals. The
microstructure of'as-cast ingots showed intercrystalline liquation, which decreased
as a function of homogenization time. After 5 hours at 15000C, almost all of the
liquation was ab-'ent in both alloys. Analogous results were obtained in the alloys
Xb-75% Zr and 65 BNT in which the critical current density after homogenization
to 7.8.103 _103
changed from-1.3.104and 2.104 and 1.2 respectively. Orig. art. has:

!TOPIC TAGS; titanium containing alloy, metal oxidation, aluminum
LBSTRACT: A study was made of binary titan ium-aluninum alloys containing 0.01, 0.87,
12.85, 5.05, and 11.20 weight percent aluminum. The alloys were twice melted in an arc
4.
~.Lu_"nace with consumable electrodes, and then forged, rolled, annealed, and planed to
ieliminate the oxygen-saturated layer. The polished samples had dimensions of 1.2 x 1.2;
:X 1.5 am, wit]h an opening 2 mm in diameter. A day before the experiment, the samples
;were degreased in benzene and stored in a desiccator. The samples were charged into a
!resistance furnace with a working chamber 150 x 400 mm, heated to the given temperature..
iTeriperature variations in the furnace did not exceed + 5%- In some of the oxperiments`-
!stea.-, was supplied at a temperature of 6000. In this case, the atmosphere of the
ifurnace contained 60-70% water vapor. The rate of oxidation was detarmined by the
Igravimetric method. The effect of alloying on heat resi stance was evaluated from the

relative change in weight of the samples. Phase analysis of -,',he scale and ol" t-he
!layers beneath the scale was done on a Type MS-501 diffractometer. The ex-perij;ental
iresults T.-ithrespect to the relative weight change of the alloys as a function of
14.eri-nerature, holding time, and composition of the gas medium are shown in a series of
le-L-ve-ir and tables. Based on the experimental data it is concluded that two basic
'- - anisrr's Play a role in the process of the oxidation of titanium-aluminum al I oys.
1,01'acbeleration of diffusion through the scale due to a shift of the ionic equilibrium
,as.a result of the entrance of trivalent aluminum ions into the titanium dioxide
2--ttice; 2) slowing down of the oxidat3.on when the amount of aluminum oxide in the
':scale increases to such an extent that there is formed a more or less thick layer of
A12.0 which hinders the diffusion of the titanium ions. Orig. art. has t, 2 figures

of single crystals of silicon,~Iorientcd to show the 111 plane
and etched in a mixture of HV, HNO 3 and (CH3CO)20 in the ratio
of 1:3:3. The origin of this structure appears to be cry5tal-
lisation at a temperature below the temperature at which certain
impurities separate out from the molt. Here, dendritic growth
is most frequent when crystals are pulled out of technical sil-
icon (purity 99.7 - 99.80%). Dendrites are developed in-the
Ill planes and when a section across them is cut in the Ill
plane a picture is obtained which is very like that found in the
octahedral slipping in crystal of Ge and Si when dislocations are
developed. In purer materials dendrite formation is coanected

a melt in a vacuum has been observed (on the free surface of the
melt). Tile purer the Si the greater the supercooling at which
dendritic growth begins and the slower the growth is.

TITLE: Twine and dislocations in silicon single crystals
PERIODICAL: Pizika tverdogo tela, v. 3, no. 1, 1961, 289-296
TEXT: It was the aim of the authors to study the twin formation in the
growth of silicon single crystals, and to investigate the Interaction
between twins and dislocations. Twine containing Si single crystals,
grown in the [111] and [110] directions by the Chokhral'okiy method were
used for the purpose; the position of the twins was determined after
etching in 10% NaOH at 65-800C (20 min); the dislocation density was
determined from the etch pits in longitudinal and cross sections of
crystals with (111) orientation., For counting the etch pits an MHH-SM
(MIM-8M) microscope was used (225x). The orientation of the specimens
was determined from Laue patterns. The outward appearance of the twins
is shown in Fig. 1 (a - growth axis [111]; b - [1103). The experimental
results indicate that the twin boundary actually hinders dislocations

from penetrating into the twinned part of the crystal; this is explained
by the fact that on the twin boundary$ dislocations accumulate (Fig, 4)
and form a glide plane. However, it also happens that dislocations slip
through this barrier (Fig. 3) as, e.g., in the case of crystals growing
in the [110] direction. If one assumes that an axial temperature
gradient during the growth of the crystal block is the main reason of
sliding, it is possible to estimate the probability of sliding in the
crystal or in the twin. In this case, the entire tangential stress
acting upon the glide plane t1ill may be calculated, considering the
change in orientation of this plans relative to the growth axis during
twinning. Table 2 gives data on the change in orientation of the (111)
planes after twinning for the three main directions cf growth.
Calculation of the tangential stresses Otan led to the following result:

TITLE: Method of detecting dislocations in Si single crystals
PERIODICAL: Zavodskaya la~oratoriya, v. 28, no. 4, 1962, 459-462
TEM. To make dislocations in Si single crystals apparent, a 15-25 min
thermal treatment of the crystals at 850-900 OC in vacuo ( -1-10-5 mm 11g)
and cooling at a rate of - 40 OC/min is suggested. The decorating of dis-
locations with copper in H2 atmosphere is even more efficient. The tests
were made with n-type and p-type single crystals prepared by Chokhraltskiyls
method. Before thermal treatment, the specimens were ground with boron
carbide and V414 (M14) powder. After thermal treatment, they were polished
in acid cP -8 (SR-8) mixture and etched in HP : HNO 3 : (CH3CO)20 = 1 '. 3 %:3.
The pits were counted with an M VJ~l -81,1 (MIM-8M) metallographic microscope.
It was found that the thermal treatment did not change density and position

of the dislocations. The form of the etched figures obsurved depended on
the heat treatment and on the decorating method. Dendritic inhomogeneities
and stratified distribution of impurities were observed. The thermal pre-
treatment increases the sensitivity of chemical etching as well as the
possibility of metallographically detecting inhomogeneities. There are 5

'ABSTPACT: The formation of 90-degree twins takes place by deviation of the growth
:direction from the [ill] axis and i:; due to asymmetry in the thermal field or to
.disorientation of the seed crystal, or to a combination of these two factors. The
transition from clear faces to indistinct faces during twin growth is accompanibd:.-
by the formation of twin laminae of adjustment. Etca tests show that a zone with
dendritic structure occurs immediately next the face of a 90-degree-twin. X-ray
studies indicate no deviation from monocrystalline structure, however. The most
likely cause of the dendritic structure is local super-cooling, which may occur in
the Czoehralski method because of asymmetry in the thermal field (which is one of

ABSTRACT: This is a c0 tion of earlier work by the authors (M V. T, 922,

authors present, using the diffusion of indium in silicon as an example, new re-
sults to confirm that the diffusion along the dislocations is much faster than.
through the volume. The investigations were made on "sitting" dislocations.
p-type silicon samples were usedL With specific resistivity 18 ohm-cm and average
dislocation density Nd _.104 CIC22. The samples were cut from a specially grown

ingot., which contained dislocations of only one kind, "sitting" dislocations par-
allel strictly to the growth axis (110). The diffusing indium was tagged with
a 0 4,
In:13-4. The diffusion from the gas phase in quartz ampoules is accur te to I -
torr at temperatures 1010--1270C. The distribution of the Indium was determined by',
Iremoval of layers. In paraUeLwith this methodj. autoradiographic study of the dif-I
fusion was also made to exclude the possibility of simultaneous existence of other
diffusion mechanisms. The data yielded for the diffusion coefficient and diffusio
of 104 C
heat along the dislocations values m2/sec and 77 kr.,al/mole, respectively,
as against 16.5 cm2/sec and 90 kcal/mole for volume diffusAon. A criterion is in-
1troduced, making it possible to estimate the influence of volume diffusion on the
form of the concenteration curve, and it is shown that the diffusion actual3y ob-
served takes place along Ithe dislocations and cannot be attributed to the settling
of indium on tb-? dislocations when the sample is cooled. The dimension of the
effective diffusion region around the dielocationsi is'determined by ari-indepen-
.1 dent electron transport method., and is found to be Of the order of 100 1. Orig.

ABSTRACT: Two ternary systems were Investigated in the experiments:
HF-HNO -H20'and HF-CrO-A-H,,O. The system HF-HN03-H?O w" used to estab-
lish tK optimum*regioli f6r the polishing of ik_~st~'~e2wpingle crystal,
and the system HF-Cr0j-H2O for the optimiim region for etching to expose
dislocations."
1~ The of ect of concentration of individual componen# of
the HF-HN03-H 0 system on the quality of the polished surface was,'doter-
mined by setting up a triangular concentration diagram. The diagram was
constructed with data from the study of 230 tested solutions and is
given in the article. A P-1gure Bhows.'the dependence of t',.e rate of sol-
ution of silicon with an ihorease In the concentration of HN03 and the

chemically polished silicon in the mixture HF-OrO3-H20. These experi-
mental data are also exhibited in the form of a triangular diagram. It
was established that the rate of solution of silicon in the optimum
regions of the system HF-HN03-H20 is approximately 100 times greater
than in the corresponding regions of the system HF-CrOYH20- Orig. art.

TITLE: Training of Concrete Workers (Podgotovka betonshchikov)
PERIODICAL: Professionallno - Tekhnicheskoye Obrazovaniye, 1957, # 11,
p 14-15 (USSR)
ABSTRACT: The article contains particulars on the theoretical instruction
of concrete-reinforcement workers at the Construction School
# 7, Kiyev (Stroitellnaya shkola # 7, Kiyev). The students
are required to pass special courses in technology and knowledge
of materials. In general it provides for the study of advanced
methods of labor and of the latest techniques in performing
reinforcement and concrete work. How the training is conducted
is described by a few examples, such as information on the
parts of a building and the order of carrying out construction
work; straightening and sorting of the steel rods, the drawing
out and cutting of the wire rod; and electrical butt welding.
On one occasion the students were shown an entirely new device -
a multiple point welding machine "BHHCTO" for welding screens
up to 2,5 m length.

ABSTRACT: There are practical difficulties in depositing elecu'-ro-
lytically a copper-zinc alloy; copper and zinc, however,
can be deposited separately without difficulty and this is
the principle of the "galvanothermic" method of making
bimetal. The zinc and copper are deposited on the steel
in thin layers which diffuse into each other on annealing.
The investigation of this process is described in the
present article, The steel was first coated thinly with
nickel and then with copper and zinc in acid electrolytes
to give a total thickness of 30 or 90.4. AnnealinG was
carried out in a reducing atmosphere and specimens were

then subjected to microscopic analysis, to chemical analysis
of different layers and to deformation tests. Graphs show
changes in composition with depth for specimens treated

PERIODICAL: "'Vestnik hlashinostroehivall (Engineering Journal), 1957,
No.4, pp. 60 - 64 (U.S.S.Ro)
ABSTRACT: Investigations on hydro-fluoriG boron electrolytes are
reported containing between 17 and 125 g/litre of copper in
the form of hydrofluoric boron salts. The raw materials for
preparing the electrolyte were hydrofluoric acid, boric acid
and copper sulphate first transformed into copper carbonate.
The method of obtaining the electrolyte is described in detail.
The copper content in the bath was determined by the electro-
lytic or the volume method. The analytical procedure is des-
cribed. For all electrolytes the upper limit of the permissible
current density at different temperatures was determined both
at rest and when sti=ed by air. The porosity of coatinge
(depending on their thickness), the strength of the bond with
the parent metal and the capacity of copper-plated steel to
be deformed in press tools were found. Specimens of low
1/3 carbon steel were degreased, subjected to anodic treatment in
an alkaline solution and plated with a nickel undercoat of

1 p thickness. It is not necessary "Oo obtain a coml
dense nickel coat. The copper coat forms bridges through the
pores of the nickel. The solution of iron in the pores is
retarded by cathodic polarisation. The adhesion strength of
the copper coat was determined by repeated bending tests, by
the Ericson drawing test and bj annealing. Bad adhesion was
obtained with a very thin (0.2 [t) or a very thick (5 p) nickel
undercoat. The tests are summrised in tables and graphs. The
distinguishing feature of hydrofluoric boron electrolytes,
compared with sulphates, is a much greater permissible current
densit-g. This rises with the concentration of the copper salt.
At 20 C and 17 g/litre copper in the form of hydrofluoric 2
boron salt, good deposits are obtained with a density of 2 A/dm
With a copper concentration of 125 g/litre the permissible
current density rises- to 25-30 A/dm . A high temperature and
stirring of t-he electrolyte help to increase the permissible
current densi4. In the dilute bath an increase of temperature
from 20 to ~5 0 raises the permissible current density from
2 to 5 A/dm , whilst In the concentrated bath the value rises
from 20 to 65 A/dm - Stirring by air increases the pe2missible
2/3 density almost two-f old. Non-porous copper coats from electro-
lytes of medium concentration (80 g/litre) are obtained if

PERIODICAL: Izvediya Vysshikh Uchebnykh Zavedeniy, Tsvetnaya

ABSTRACT: The object of the investigation described in this paper
was to study the effect of various factors on electro4e-
position of nickel from fluoborate solutions and on the
quality of the deposits obtained by this method. For
the preparation of the HBF4 solution, chemically pure
H3BO3 and an BF solution (whose concentration was deter-
mined from its density) were used in the stoichiometric
ratio, H 3BO3 being added (a small quantity at a time)
to the continuously stirred and ice-cooled HF solution.
To the obtained IMP4 solution, also continuously cooled,
nickel carbonate (a small quantity at a time) was added
and in this manner it was possible to-obtain solutions

fludborate (density approx. 1-5), which could then be
diluted to any required concentration. The characteristics
of the experimental electrolytes (pH = 3 in all cases)
are given in Table 1 which shows the nickel concentration
(N = 1 to 4), the coatent (in g/litre) of fluorine, Fl,
present in the form of BF,OH' the content of fluorine, F 21
present in the form of BF.-, the total fluorine content
F = F1 + F2 1 the B content, the F/B and F/Ni ratios,
the NiCl 2* 6H20 content, and the density at 20 00. Nickel
anodes and steel, copper or brass cathodes were used in
the experiments, the results of which are reproduced
graphically. The effect of the current density
(A/dm2) on the cathode potential is illustrated in Figure 1,
where graphs 1, 2,3 and 4 correspond to the nickel
concentrations of 1N, 2N, 3N and 4N, respectively.
Figure 2 illustrates the current-density/cathode-potential

(graph 1) and with 5, 10 and 156/litre H 3BO3 in excess
of the stoichiometric ratio (graphs 2,3 and 4). The
results of the tests in which the current-density/cathode-
potential relationship was B8udied for 3K electrolytes
containing no C1 ions at 20 C a6Ld those containing 15, 30
and 50 S/litre NiCl 2' 6H20 at 50 C are reproduce?d in
Pigure 3 (graphs 1, 2, 3 and 4, respectively). The same
relationship for a 3N electrSlyte with no excess of
H3BO3 at 20, 30, 40 and 50 C is shown in Figure 4 (graphs
1 to 4). A 3N electrolyte was also used for investigating
the effect of the pH number which was varied between 1 and
5 by means of HBF or sodium iodide additions. It was
found that at pi&= 5 , the electrolyte is unstable and
contains black,, insoluble particles (most l1kely Ni(OH)2 wit
basic Wilts) held in suspension. Pitting occurs and a
dendritic deposit is obtained which at low current densities
Card3/8 (1 to 5 A/dm 2) becomes dark. At pH = 4 , low current

densities result in a dark deposib, while dendrites are
formed at high current densities. At pH = 1 or 2 ,
intensive evolution of hydrogen takes place on the cathode
surface, the evolved gas forming bubbles which adhere to
the cathode and cause pitting. Best qualty deposits are
obtained at PH = 3 . Yield per unit current varies in
all cases between 89.6 and 99.?0161 increasing with increasing
current density and at high pH (3 to 4) values, and falling
sharply at low current densities and at pR = 1 or 2 .
In the next stage of the investigation the anodic processes
were studied. Four ty es of electrolytes were used
containing (in S/litre3: (A) 25 Ni(BF 4)21 68*5 Fl,
138.7 F2 and 34.4 B; (B) same as (A) P11's 15 NiCl2'6H20;
(C) 240 NiSO 4-7"20, 30 H3B03; (D) same as (C) plus
20 NaCl. Cathodes were made of electrolytic nickel or of
non-paselvating nickel containing C 0.2%, Si 0.2% and 3 0.00
(Ref 12). To reduce to minimum the difference between their
Card4/8 true and the geometric surface areas, the cathodes were

polished first mechanically and then electrolytically
(to remove the plastically deformed layer). The results,
in the form of graphs showing the relationship between
the anodic current density and the. anode potential, are
reproduced in Figure 5: graph (1 non-passivating nickel
anode in electrol te C; graph (2~ _- as (1) but electrolyte
D used; graph (35 - non-passivating nickel anode in
electrolyte A; graph (4) - as (3) but in electrolyte B;
graphs (5) and (6) - electrolytic nickel anode in electro-
lytes C and D, respectively. When the ratio of the anode
and cathode surface areas was Sa/Sk = 2:1, the yield of
the dissolved metal per knit current was high even in the
absence of chlorides in the electrolyte but for
Sa/Sk = 1:1, a slightly lower yield was obtained. After
the bath was operated for the equivalent of 800 A.hour
per 1 Are of electrolyte the concentration of the nickel-
bearing salt in the solution was*unchanged and only a
slight rise in the pH number was observed. In their
Card5/8 conclusions the authors state that: i) the main advantage
SOV/149-58-5-14/18
Electrode Processes in Electro-deposition of Nickel From Fluoborate
Electrolyte
to be gained by using the fluoborate electrolyte instead
of a sulphate solution for nickel plating is that the process
can be intensified, i.e. higher current densities can be
employed without affecting the quality of the deposit
and yet without reducing the yield per unit current. The
maximum permissible current density can be increased by
increasing the Ni concentration in the electrolyte (up to
3N) and by using higher temperaturesi 4 when the
concentration of H3 BO3in the electrolyte is increased,
the cathode potential is reduced and so is the maximum
permissible current density. In spite of this effect,
which is probably due to partial dissociation of
Ni(BF 4)2 to Ni(BF3OH)2 and to a decrease in the activity
of the nickel ions in the electrolyte, it is recommended
to maintain the H3BO 3concentration slightly (approx.
15 g/litre) above the value corresponding to the
stoichiometric ratio, since free H3BO3 improves the
Card6/8 stability of the electrolyte and makes it less reactive;
SOV149-58-5-14/18

Electrolyte
iii) the effect of chlorides introduced in the electrolyte
in the form of NiCl2.6H2O in amounts up to 15 g/litre is
beneficial, since they reduce polarisation. However, at
high (more than 30 g/litre) chlorides concentrations, the
maximum permissible current density is lower and the 0
quality of the deposit is adversely affected. At 50 C,
the effect of the chlorine ions becomes insignificant,
most likely owing to the reduced adsorption of these ions
on the cathode surface and to sufficiently high activity
of the alaode, particularly when made of non-passivating
material. Owing to the latter factor, the fluoborate
electrolytes are quite stable, so that in operation it is
only necessary to replenish the fluoboric acid in order to
maintain constant pH, since the anodic,y-ield per unit
current is slightly higher than the cathodic;
(iv) the optimum value of the pH number of a fluoborate
solution for nickel plating is between 3 and 3.5. At
pH = 1 , the yield per unit current is too much affected

PH 4.5 , the electrolyte becomes unstable and subject to
hydrolysis and dark deposits are obtained;
(v) tendency to pitting is one of the shortcomings
of the fluoborate solutions for nickel plating. This
undesirable effect can be minimised by application of
stirring'and by addition of reagents reducing the surface
tension of the electrolyte.
