TITLE: Infectious Properties of Injured Phages
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 129, Nr 6, Pp 1421 - 1423
(USSR)
ABSTRACT: D. Fraser and co-workers (Ref 12) concluded from their investiga-
tions that the infectious activity of the destroyed preparations
of phage T2 is related to the desoxyribonucleic acid (DITA) which
was liberated from the protein covers of the phage particles by
the effect of urea. The results obtained by the authors, how-
ever, were rather divergent. Therefore, they thoroughly investi-
gated the preparations formed from bacteriophages by treatment
with urea. The following dysentery phages were used; T4r, DILI
(isolated from the soil by T. 11. Broker), an& N-2 (obtained by
F. I. Yershov, 2-y 111oakovskiy gosudaretvennyy meditainakiy
institut, Second Moscow State Medical Institute). The effect of
the phages was tested on protoplasts (bacteria without cell
walls). The authors obtained them from cells of the following
Card 1/4 bacterial strains by means of lysozyme according to R. Repaska

Infectious Properties of Injured Phages SOV120-1291-6-6il6q
Ref 13): E. coli B (sensitive to phage TO and DMI); E. coli 600
resistant to all three phages mentioned); and Sh. dys. New-
~
castle (obtained by F. 1. Yershov, sensitive to N-2). Suspen-
sions of phages, concentrated to 10 12 particles in 1 ml, were
treated with an 8 M urea solution. Thereafter, the action of
phages on intact cells was completely eliminated. They showed
an activity of 0.00001 to 0.0011%, on protoplasta. This effect
concerns bacteria strains sensitive to phages as well as those--
resistant to phages. Thus, this remaining activity cannot be
due to the preservation of a few phage particles. Further ex-.
periments showed that the above residual infectivity is not re-
lated to the free DNA which has left the virus particles. Thus,
it could be assumed that only the part of the DNA is active
which is protected against the used desoxyribonuclease by other
components of the phage (probably by proteins). In order to
-he pro-
check this assumption, the proteins were separated from 4.
parations by phenol or chlorqform. The preparations were com-
pletely inactivated in spite of the proved extensive separation
Card 2/4 of the proteins from the DNA. This proved again that, after

Infectious Properties of Injured Phagee SOV/20-129-6-61/69
treatment with urea, infectious activity is not due to free
DNA. On the other hands it has been known that the protein com-
ponent isolated from the phage cannot cause phage reproduction
in the bacteria. The only assumption is that one complex of the
DNA with the protein has infectious activity. It was serologi-
cally proved that the proteins of the active complexes mention-
ed are similar to the antigenea of normal phage particles. The
transition of 80-90,06 of activity into the precipitate could be
achieved by centrifugation of virus preparations treated with
urea as well as by suspensions of intact phages. The electron
microscope showed that the above complex has corpuscular struc-
ture and that it is of about the same size as the intact phage.
Figures 1 and 2 show that, apparently, urea destroys only the
distal parts of the processes. Thus, the phage particles become
incapable of depositing on normal bacteria. The inner part of
the process axis which consists of protein is uncovered by the
urea effect. Further experiments with trypsin, which destroyed
the uncovered part, brought about complete suppression of ac-
tivity. Thus, the protein in the axis of the phage particle is
necessary for the occurrence of the infectious activity of the
Card 3/4 preparationsmentioned. There are 1 figure and 13 references.

ABSTRACT: According to published data the silicon-nitrogen system has three
phases: SL3 N4P S'2N and SIN, where the phase S3N4with 39-.5%
nitrogen is chemizi; the most stable aM the most important in
practice. Further, the properties of Si N are described in detail
as also the method by which it is obtained from silicon powder, the
chemical composition of which is shown in table 1. Figure 1 shows
the saturation ourves of silicon by nitrogen at various tempera-
tures. Figure 2 shows the nitrogen content in silicon in dependence
of the duration of nitration at 16000. Table 2 shows the influence
exercised by an addition of silicon upon the sintering of the sili-
con nitride ' hot pressings at 14000 and 800 ka/cm;e).-In table 3
the properties of test samples of silicon nitride are describea
(Nitration temperature 15000). Also bending strength and the re-
Card 1/2 sistance against oxidation were tested in dependence on temperature.

ABSTRACT; The solubility of carbon in silicon, the phase composition
and the structure of silicon-carbon alloys as well as the
problem of the dissociation of silicon carbide in vacuum at
higher temperatures were investigated.
The investigation of the phase diagram in the system Si-C was
carried out in three parts:
l.-Determination of the solubility of carbon in silicon;
2.-Determination of the phase composition in the range Si-SiC;
3.-Explanation of the formation of the SiC phase.
For the investigation of the phase composition and the structure
of the alloys metallographic and x-ray structural analyses as
well as the determination of microhardness were carried out.
The metallographic investigations showed that the alloys
Card 1/2 consist of one phase up to 0,7% C.

Investigation of the Solubility and Phase Composition in the 78-3-4-2/38
System Silicon-Carbon
The alloys containing more than 0,8% C consist of two phases:
solid solution C in Si (light field) and silicon carbide (dark
field).
In the thermal treatment of silicon carbide in vacuum at 2000-
-21000C a complete dissociation of silicon carbide occurs with
Si evaporating and C forming a graphite residue.
The graphite lines were proved by the x-ray structure analyses.
No solubility of Si was found in silicon carbide.
There are 14 figures, 3 tables, and 5 references, 2 of which
are Soviet.

ABSTRACT: The nickel corner iri the phase diagram of the system Ni-Mo-Cr
(UP to 40% molybdenum and up to 40% chromium) was investigated
using the thermal and microscopic analysis.
Eight polythermal sections of the nickel corner in the phase
diagram nickel-molybdenilm-chromium were constructed. The phase
composition and the hardness of the alloys were investigated
at temperatures of 12700, 12000, 9500, 8000 and 7000C. The
saturation limit of the ternary solid solution o-' the
basis of nickel was determined at temperatures of 700 0, 8000,
9500 and 10000C.
It was shown that with a drop of temperature the solubility
of molybdenum and chromium in nickel decreases markedly. Also
the sectional diagrams with a constant content of
Card 1/2 4%, 8,5%, 3,5% and 20% of chromium were constructed.

ABSTRACT: Molybklontuii disilicide has good resist
tance to s-aling at
te,niperatures up to 17000C combined with other useful
propcrties (e.g. metallic alecbrical conductivity) and
the study of this compound has been )roceeding in recent
years (Refs 3-7). The authors describe their investiga-
tion of the high-teweratura mochanical )roporties of tho
c:om~)ound and of a preparation with an excess of silicon.
The disilicide was prepared by sinterinq at 1100-12000C

TITLE: The Scale-stability of Cermet Alloys Based on Titanium
Carbide (Okalinostoykost' metallokeramicheskikh splavov

PERIODICAL: Tsvetnyye Metally, 1959, Nr 3, pp 61 - 66 (USSR)
ABSTRACT: The initial materials were titanium dioxide, niob-ium
pentoxide, powdered niobium (containing 1-3% tantalum.),
tungsten carbide, lamp-black and powdered cobalt reduced
from its oxalate. Alloys were prepared by mixing for 24
hours and then heating in a hydrogen atmosphere in an
electric furnace. X-ray analysis of the specimens
prepared from individual carbides of titanium and nilob.ium.
qhov,,,ed the Iines correspond'ng to the two carbides
(TiC - 4.32 BbC - 4.46 1), whereas the alloy c,:intaining
87% TiC and 130,16 NbC shQwed only one phase with lattics
parameter 4.37 � 0.03 A' (TiC-NbC solid solution). The
microhardness of niobium carbide and of the complex
titanium-niobium carbide was shown to be 1 822 and 2 -"72
k6/mm~. All the samples of titanium-tungsten carbide were
single-phased with a crystal lattice of TiC. The
Cardl/4 powdered carbides were mixed with cobalt by wet grinding

for five days, pressed wit a stress of 1 000 kg/cm 2 and
sintered at 1 450 - 1 560 0 in hydrogen. Figures I and
2 show typical microstructures of TiC-NbC-Co ando
TiC-WC-Co. The alloys were tested at 900-1 200 C for
100 hours, the gain in weight and the thickness of oxide
layer being noted. Diagram 3 shows that with increase of
NbC in TiC-NbC-Co alloys there is a sharp decrease in weight
gain from 5-1 &12 per hour. With further increase in
NbC the weight gain is practically constant. Figure 4
shows the weight gain of alloys containing 25016 Co and
3-15PIo NbC. The scale- stability is a maximim with 15016 ITDC
at all temperatures. Further increase of NbC to 25~o' has
no further effect. Varying the cobalt content showed that
the weight gain was a minimum at 25% Co. S-Decimens prepared
from simple carbides gave similar results -',-a those prepared
from complex carbides but in all cases the formsr had a
greater weig4t gain than the latter. At 1 000 0 the
surface has/grey coloBr due to breaking up of the ecale
and at 1 100 - 1 200 C there is a thicker layer on the
Ca.rd2/4 surface. The TiC-WC--Cc. alloys were prepared from the

complex carbides. Figure 5 shows the weight gain of
alloys Sontaining 15 and 3001o WC both with 18 wt.% cobalt.
At 900 C, the weight gain is practically the same for
both alloys but at higher temperatures the 30% WC allOY
has a lower weight gain. The effect of Co content is shown
in Figure 6 (the ratio TiC:WC is 65:35). With increase
from 10 to 20016 Co there is an increase in oxidation
resistance whah is more marked at higher temperatures.
With alloys with TiC:WC ratio of 85:15 the effect of Co
increa8e is less marked. At temperatures higher than.
1 100 C all the alloys oxidise rapidly. In 'both TiC-ITbC
and TiC-WC alloys oxidation spreads in the first instance
along the cementing phase. The TLC-NbC-WC-Co alloy
containing 10-15% NbC has better scale stability thaa
TiC-WC-Co alloys but not as good as TiC-RbC-CS alloys. The
TiC-15NbC-25Co alloy is suitable up to 1 100 C and the
TiC-30WC-15-2OCo up to 900 C.

pieces 15 nim diameter and 5 mm high. The specimens
were held at the test temperature for 20 min before
applying the load of 30 see duration; not less than
six measurements were taken at each temperature, each
new test temperature being attained by cooling. After
cooling to room temperature, the specimens were
photographed (x 420), the diagonals of the indentation
were measured and the VPN values were found from the
tables. The results are reproduced in the form of an
Hv(kg/mm2) versus WC) curve in Fig la (curve 3) where,
for comparison, the results obtained by other workers are
also shown: curve 10 based on the measurements of
Betaneli (Ref 5), who used a 250 kg load, and curve 2,
based on data due to Kazakov (Ref 6), who used a 1 kg load.
It will be seen that hardness of TsMA-332 decreases
monotonically and linearly with rising temperature from
about 1800 VPN at room temperature to about 600 at 10000C
and to 350 at 1100%, Fig la shows photographs of the

loading of the brittle specimens and the results of any
test, in which fracture of the test piece occurred at a
distance of more than 5 mm from its centre, were ignored.
UTS of TsM-332 determined in this manner was 15 to
16 kg/mm2. In the final series of experiments, the
compressive strength of TBM-332 was determined on
cylindrical specimens (10 mm diameter and 15 mm thick),
tested on a 30 t hydraulic machine equipped with hard
alloy supports. 90 Specimens, taken from two batches of
TsM-332, were tested; the scatter of the results amounted
to 20%. The average values of the compressive strengths
equal to 80 to go kg/mm2, were much lower than those
obtained by other workers. In the conclusions, it is
claimed that the results of the present investigation are
more accurate,than those quoted in the literature.

TEXT: Mo disilicide has recently gained in interest because of its exceptionally
high scale- resistance up to 1700oC, especially in the making of heating elements for
resistance-type electric furnaces. Three Mo-Si compounds are known to exist:
M03Si, M03S'z, and MoSi?. R. Kieffer Is and E. Cerwenka's phase diagram (Zs. f.
Metallkunde, v. 43'. no. 4. 1952) is used. Si solubility in Mo at 12000 is 0. 15% and
at 14000 0.8% Si. The types of crystalline lattice, densitiess m. p. 'at and micro-
hardnesses (100-g load) of the three compounds are tabulated'MoSi2 is a metallic
conductor of electricity (21 [Lohm/cm) and is the most highly Cale-resistant Mo-Si
compound, owing to the formation on it of a dense and strong vitreous SiO2film,
0. 03 to 0. 1 mm thick. Oxidation at 1350-14000C is most effective. Above 17000
the SiOz film melts, coagulates in droplets, and loses its protective properties.
The oxidation mechanism of Mo disilicide changes abruptly at 450-600" at which
point a rapid intercrystalline corrosional disintegration takes place. Whereas in-
candescence at 1200- 15000 over thousands of hours does not produce either an
increase or a loss in weight, 30-50 hours oxidation at 5000 will redu.ce the disilicide

to powder (except under a shielding atmosphere). Mo disilicide is termed brittle 2
and of medium hardness. Compressive strength at -room temperature is 70 kg/mn-i
bending strength at 12000 is 37 kg/mm2; 100-hour strength at I 1000C is 6. 3 kg/mm Z
(all three values0from Western sources). It is high-temperature plastic; creep
strength at 1000 is termed unsatisfactory. If Mo disilicide is to be employed, e.g.,
irl will enhance its
,gas-turbine parts, cementing substances must be found that
toughness and strength. Unfortunately, attempts to produce sintered combinations
of MoSi2 with various metals have not been successful. The MoSiZ for the subject
experiments (work done in 1952-3) was made of powdered Mo (grains up to 311) with
0.00576 Fe. 0.00216 Ni, 0.03% 0 . and of thoroughly ground Si (2 ~L) with 0.087o Al,
0.037o Ga, 0.015% Mg, 0.015% ie. The two powders, taken in stoichiometric ratio
(63.147o Mo, 36.8676 Si),were thoroughly mixed in alcohol for 48 hours. Cylindrical
specimens 50x25 mm were sintered from this mixture at 1100-12000 (3- 1 min hold-
ing). The special graphite pressing dies were compressed at 150 kg/cm - The
Mosiz formation is fast and complete; the fracture of the specimen is steel-gray
in color with a metallic gloss. The specimen surface forms a thin carbide crust in
contact with the graphite. The results of three chemical analyses are tabulated.
The MoSi2 was once more nd to a fine powder (grain size 2 ~L) and subjected to

a second s"intering at 1500!lr5o5u int3 6xbx6o-mm rectangular rods. The unit
weight increased to 6.11-6.13 g/cm owing to reduced porosity. X-ray analysis

ABSTRACT: In this paper, the results of an investigation of the
refractoriness of Ti-Nby'~and Ti-WAbase alloys produced
by p2wder metallurgy,gle-thods (carbide solid solutions)
with Co as binder are reported, The influence of the
NbC,, WC and the binding metal on the mechanical properties
of TIC alloys has been studied at room temperature and
at elevated temperatures in short-term and long-term
tests. The experimental alloys were made by methods
generally used for the manufacture of titanium carbides.
The complex carbides TiC-WC, TiC-NbC and pure powdered
cobalt were used as the starting materials. The complex
carbides were prepared by water quenching a mixture of
fine powders of the respective simple carbides from
2000 to 22000C. In the TiC-Nb-Co alloys, the NbC
content was varied from 0 to 25% and the Co content from
5 to 40% (remainder TiC), and in the TiC-WC-Co alloys,

carried out in a specially constructed device with a

supports made of a heat resisting carbide and fractured
with a concentrated load; the distance between the
supports was 30 mm. and the speed of loading was
11 mm/minute. The temperature was measured by a
Pt/Pt-Rh thermocouple, the junction of which was in
direct contact with the specimen. For the determination
of the UTS in tension and the long term refractoriness,
flat radiused specimens, as proposed by S. V. Serensen,
were used. The main feature of the high--E-emperature
testing of these specimens (Fig 1) is the fact that up
to a given maximum temperatiire only the central "working"
portion of the specimen is heated; the ends of the
specimen which are fixed in grips are outside the hot
Card 2/5 zone of the furnace. The temperature of the "cold" ends

of the specimen does not exceed 800 to 9000C in the case
of the upper, and 700 to 8000C in the case of the lower
ends. The electric furnaces with a single piece tubular
platinum heaterl type P-I-1350, enable lengthy tests to
be carried out at temperatures of up to 13500C. The
furnace is attached to the creep testing maching DST-5000,
which has been specially reconstructed for testing cermet
specimens and has been re-equipped with electrical Sear
registration and regulation apparatus (potentiometers).
Damping asbestos packing was inserted under the supporting
surfaces of the side faces of the specimen adjoining the
grips. The temperature was measured with the Pt/Pt-Rh
thermocouple passing through an orifice in the solid
platinum heater; the junction was placed within 0.5 to
1 mm of the central portion of the specimen. Short term
tests to fracture at high temperatures were carried out
with the same machines and attachments as the long term
(100 hours) tests. Fio- 2 shows the UTS in bending of
TiC-IIqbC-Co (10 to 15% NbC) alloys in relation to cobalt
content (1 - at 200C; 2 - at 16000C). Fig 3 s"hows the
Card 3/5 UTS in bending of TiC-NbC-Co (2501o Co) alloys in relation

to NbC content. Fig 4 shows the chanGe in UTS on straining
a TiC-NbC-Co alloy in relation to temperature.FiG 5 shows
the UTS in bending of TiC-WC-Co alloys containing 300/66 VIC
at 10 and 23yo Co, in relation to temperature (I - 10% Co;
2 - 23% Co). Fig 6 shows the change in UTS in tension
of a TiC-WC-Co alloy of the basic composition (65 : 35)
+ 1,CP/0' c0, in relation to temperature; Fit, 7 shows the
limiting long-term (100 hours) refractoriness of a
TiC-'WC-Co alloy of the original composition (1 - 950OC;
2 - 11000C). For the investigated cermets, the
relationship Ob/ abending := 1 - 2 (approximately 5C%) is
characteristic. The spec fic gravity of the TiC-NbC-Co
alloys is 5.9 to 6.2 g/cm~ and that of the TiC-WC-Co alloys
u
is 6.5 to 7 g/cm3. For the determination of the modulus
of elasticity of the experimental alloys, the angle of
bend under various loads was measured directly and from
that, the value of E was calculated by a well knoun
formula. The specimens were plates 0.3 to 0.5 mm thick,
made by compressing and sintering plates of 1 mm thickness
and subsequently grinding with boron carbide. The tests
Card 4/5 were carried out at room temperature in a device made

by B. I. Pribilov. The specimens were placed on
refractory supports and loaded gradually with loads of
50 to 1000 g. The degree of bending was measured with
a micrometer. For TiC-Nb~_Co alloys, E was found to
be 30 500 Go 31 500 kg4mm , and for TiC-WC-Co alloys,
38 000 to 40 000 kg/mm'. There are 7 figures and 3
referencas, 2 of which are Soviet and 1 German.
