TEXT.- The conductivity variations of n-Ge irradiated by a flux of 14.2 MeV
neutrons-was investigated. The initial conductivity of the specimens was 0.2837
ohm-l-em 1. In order to reduce the effect of the t 'emperature variations of the
surrounding medium, the specimens were placed In a thermostat (temperature
30 + 0.050C). The cond ctivity variation of the specimens after 15 hour-irradia-
tio-n by a flux of 5.1N neutron/see was as low as - 0.75%. In the specimens which
werp not placed'in the thermostat even that small variation was not noticed. The
rate of removal of the carriers was 'determined as equal to 25 carriers per neu-
tron. A possibility was obtained to detect the dependence previously assumed
(RZh Fiz, 1960, no. 9; 23850) of the carrier removal rate on the initial carrier

TITLEt Influence of Lithium, Zinc, and Magnesium Upon the State of the
Crystal Lattice of Aluminum (Vliyaniye litiya, tsinka i. magnJAya

ABSTRACTi This is an investigation of the influence of alloying elemen~.s
upon the state of the crystal lattice of aluminum. For this
purpose the alloy was investigated in its original state, in
which the atoms of the alloying element are homogeneously
distributed in the solid solution. The experiments were carriei
out at room and at elevated temperatuxes with pure AVOOO aiuminm
and with binary alloys of aluminum. The experiments showed that
the introduction of lithium and zinc into alumiro;n (to a limit
of 2%) leads to a weakening of the interatomic bonds. At
elevated temperatures the lattice dimensions of the solid
solutions of zinc increase less than those of lithium solutiollB.
This can to a certain extent be explained by a gradual transition
of the lithium ions into the atomic state at elevated temperatires,
Card 1/2 This explanation can be offered if reasoning is conducted

Influence of Lithium, Zinc, and Magnesium Upon the S0111163-59-1-36150
State of the Crystal Lattice of Alu=inu=
according to the viewpoint of Zamotorin (Ref 7). The
experiments showed that the presence of consi4erable dynamic
distortions in the crystal lattice of the sruce Al-Li alloys
does not lead to an increase in strength. So do only static
distortions of the alloy lattice- An increased stability of
the lattice of Al-Mg alloys at elevated temperatures was found
in the course of the experiments, This is explained by the
strengthening of the interatomic bonds.. Apart from tha factors
enumerated in the papers (Refs 3, 5. and 9) the increase of the
linkage forces represents the main causa for the increase
of the recrystallization temperature and of the energy required
for the acceleration of the diffusion of magnesium in solid
Al-Mg solutions. There are 4 figures and 9 references. 8 of
which are Soviet.

No. 4, pp. 131-136
TM; V.I. Danilova and M.A. Levashevich (Ref. 1), Hofmann and Falkenhagen
(Ref. 2) and Hahnemann and Schrade (Ref. 3) studied the effect of high-speed cooling
on the strength of Al-base alloys. The authors investigated this effect on the
struetura and properties of binary Al-Gr and Al-Mn alloys, A crystallization rate
of 50,000 degrees/see was attained by catapulting the liquid melt (at 9000C) on a
cold copper support. The crystallization rate was determined by an oscillograph.
High-speed cooling makes it possible to obtain a number of solid Al-base solutions
from the liquid state with a wider concentration range of some components than
provided by the structural phase diagram. At a cooling rate of 50,000 degrees/see
the chromium content in +,he solid solution attains 5.7 weight %. At the same rate
the maximum amount of manganese in the solid solution exceeds 10 weight %. High-
speed cooled alloys, prepared in the form of thin plates, were tested on a special
device built at the University laboratory. It was established that Al-base alloys

The Effect of High-Speed Cooling on the Structure and Properties of Aluminum Alloys
crystallizing during high-speed cooling acquired a high ultimate strength without
any considerable loss in their ductility.. The ultimate strength of an Al-alloy
with 5.7% Cr was as high as 60 kg/mm2. The phase composition of the alloys was
investigated using the method of determining the paramagnetic susceptibility
(described in Reference 4 by F.S. Smirnov). It was found that a homogeneous solid
solution was formed in Al-Mn alloys containing 5% Mn. If the Mn content increased
up to 10%, a low amount of a metastable A144n phase was revealed. In Al-Cr alloys
a homogeneous solid solution was formed at a Cr content up to 1.8%. A further
increase in the Cr content entailed the formation of a metastable A14Cr phase and
the solid solution was supersaturated up to 5.7% Cr. The Al-base solid solution,
oversaturated with Cr, began to disintegrate within a range of 450-5500C (depending
on the Cr content). A solid solution saturated to the limit point underwent a
two-phase disintegration. There are 5 graphs and 4 references- 2 Soviet and 2
German.

ABSTRACT: The aim of the work described in this paper was to
investigate the influence of plastic deformation of
cast and hot-pressed specimens on the changes in the
mechanical prop~-,rties; and in the sub-microstructurelyof a
now alloy _9L8__UY6__ontaining 11.5% Mg, 0.14% Be, 0.1% Ti,
0.194, Zr, rest Grade WOO aluminium. Ingots of this
alloy were produced in a 120 mm dia metal mould, applying
by means of a piston a specific pressure of 1300 kg/cm 2
during the process of crystallisation. The thus-produced
ingots were heat-treated (soaked at 435 0C for 20 hours
and subsequently quenched in hot water). One batch of
the specimens were investigated in the cast and heat-treated
state. A part of another batch was subjected to cold-
Cardl/3 working to the extent of 25, 50 and 755'; a second gart
of this batch was subjected to hot pre:sing at 420 C q,,-

and some of these specimens of the pressed and heat-
treated alloy were also subjected to subsequent cold-
working to the extent of 25 and 50%. The results of
testing the mechanical properties of specimens after
various types of deformation are given in Table 1. The
average results of the mechanical tests (at -60, 120, +150
and +200 0C) of hot-pressed specimens are entered in
Table 2. Results of hardness tests of type-II stresses
of the dependence of the block dimensions on the degree
of deformation and other results are entered in graphs.
The results of extensive tests have shown that this new
Al-Mg alloy containing Mg and very small additions
of Be, Zr and Ti is suitable for producing semis by hot
pressing. Components from this new alloy can be manu-
factured directly from hot-pressed rods and also from
cold-worked material. The alloy AL8-U was originally
proposed by N.N. Beloumov, A.A. Dodonov, V.A. Yegorov.

ABSTRACT. Aa-Mn, Al-Cr and Al-Mg alloys, pro duced by rapid cooling from a liquid
state, were subjected to x-ray, metallographic and.electrio conductivity studies. The
alloys, with up to 11% Mn, 5. 7% Cr and 11% Mg,were cooled at a rate of 50, 0001/sec by
catapulting the liquid melt at 800-890 C onto a cold copper plate; this yielded 0. 1-0. 3-mm
films. Rapid cooling was found to affect the density of the lattice electron cloud and to
produce dendritic formations in the microstructure of alloys with up to 1% Mn, while

alloys with a higher percentage of Mn produced ffitracrystalline liquation. The micro-
hardness of the films showed a steady and sharp Increase up to 9% Mn In the solid solution
and a microhardndss ma)dmum. of 94,j-.,,/mm2 w"'attained for alloys with 5.7% Cr in th
super saturated solid solution. A study 61 the relative paramagnetic susceptibility, used
to determine the homogeneity of the soludons, Indicated that a homogeneous solid solution,
with, less than 6% Mn and 2% Cr, crystallizos with'k rapid cooling of the AI-Mn andkl-
Cr solutions, respectively. In a test with an alloy'of AI-Mg (11%), Be (0. 12%),
Zr (0. 17%), and Ti (0. 09%), to which 0. 42, 0.80 ahd 1. 32% Mn was added, Mn was found
to inhibit,,the diffualon processes in the alloys markedly when its content was approxi-

ABSTRACT: The power station, which comm need operation in 1948,

three-drum Steinmuller boilers evaporate 100 t/h and have been
reconstructed to burn anthracite duff. The other arrange-
ments are described in detail.
The reliability of the equipment is described. Theie were
several emergency stops of the turbine from full load because
the thrust blocks were inadequate, the high pressure glands
were also unsatisfactory. 'The emergency stops caused damage
to the boilers, particularly to the primary radiation; super-
heaters and both primary and secondary superheaters were dam-
aged during lighting up of the boilers. The water economisers

The proceduie for starting up is described from lighting
up of the boilers. When the pressure at the turbine stop
valve has reached 55 dtm. the turbine is started and it runs
up to speed as the boiler pressure rises. The total t-.*Lme
required from commencement of firing to connection of the set
is 5 - 6 hours and full load is taken up after ? -8 hours.
However, high speed starting trials have shown that full load
can be taken three hours after starting up.
Major overhauls are carried out on an entire set at once
and take 5?0 hours for the two boilers, employing 120 - 200 men.
Overhaul of the turbo-generators occupies 36 - 38 men for 540
hours. The utilisation factor of the equipment at the start
of operation in 1949 was 70.4c.in the boiler house and 55-7 in
the machine room. In 1954 the corresponding figures wen

The Dractice of running up the turbine whilst pressure is
building up in the boilers is fully justified. The operation
of boilers working in block systems should be made more relia-
ble by preventing slag formation on the heatin6 surfaces and by
providing an effective method of cleaninG the convective super-
heaters and using gas flow speed in 'the tail end of the
boiler not greater than 8 m/sec; the makers should provide
protection against wear.

ABSTRACT: At the present time, large, new high pressure power
stations are being built on the boiler/turbine block
system with reheat. The existing procedure for start-
ing such equipment from the cold consists of a number
of successive operations; lighting the boiler, raising
pressure, heatin pipework.,.heating and loading the
"guld take up to 48 hours and it was
turbine. This c
necessary to develop new methods of starting up block
installations.
A method of simultaneous firing the boiler and
starting the turbine for block sets without reheat was
developed by two of the present authors. The -,presence
Card 1/8 of reheat complicates the procedure because thi inter-
mediate superheater must be cooled by steam and only
later connected into operation on the turbine already

working. In order to avoid damage to the tubes befoie
connecting the reheater into circuit it is usual to
cease firing the boiler for a time. Complicated arrang-
ements are required to reconnect the pipework during
the operation.
The Nesvetay regional power station was selected for
tests on the block starting of seta with reheat and a
great deal of work was done there in 1956 to accelerate
the starting procedure.
The block consists of a turbo-set of 50 MW operat-
ing on steam at 115 atm., 485 C, with reheat to 440 C
at 38 atm. using two boilers with an output of 120 t/h,
one continually operating turbijie driven feed pump and
two electrically driven pumps. A schematic circuit
diagram is given in Fig. 1.
The original barring gear was not self-disconnecting.
It was found that the steam pressure required to accel-
erate the turbine could be much reduced by increasing
the barring speed. A mome povierful barring motor was
Card 2/8 installed and arrangements were made to disconnect it

set. A number of thermocouples were installed at
various positions in the boilers and turbine and their
locations are given in Figs. 2 and 3- Expansion of
the turbine cylinders and rotors was measured.
The first block start of the turbine and one boiler
was made on-February 20, 1957. The pieparatory measures
an described in detail. Before the start a table of
starting conditions (Table 1) was drawn up based on the
results of block starts on a tuibine BK-100-2. The
starting procedure is described and graphs are plotted
in Fig. 4 of the changes in steam conditions and con-
sumption, speed, power and expansion of the hiol pre--s-
ure cylinder of 'the turbine as a function of tine
during this first start. The start was completed in
just over 4 1/4 hours. The unusual rate of startin-
and the absence of data about conditions for heatinE;
the turbine made it necessary to run up to speed slowly
so that the turbine operated for a long time without
Card 3/8 load. As was to 0be expected this caused some over-
heating (to 140 C) of the lower pressure sections of
the turbine. After the turbine had been loaded up to

Block starting of 50 MW set with reh
pat. (Cont

5-8 MIV0the temperature of the exhaust steam was reduced
to 2? C which corresponded to the pressure in the
condenser. The temperatures of the front vralls of the
superheater tubes cooled by low pressure steam are
given in Fig. 5 and 6. During the entire operation of
starting these temperatures were much lower than durinc,
norm 1 operation and did not limit the rate of raisj-n;];
pressure. The turbine operated at full load for 6
hours and -was then unloaded to 25 MW- One boiler was
extinguished and the pressure in the remaining boiler
.vas gradually reduced until after four hours the set
was completely unloaded.
On February 22, 195?, after the set had stood for
30 hours a sucond block start was made with both boil-
ers being lit together and both connected to the tur-
bine from the start. During the first start it was
found th# in all parts of the steam line the steam
temperati(re was from the beginning above the saturation
card 4/8 piessurd. Therefore, the second start was made with
fully closed drainage cocks on all steam lines which
facilitated the application of vacuum and caused no

difficulties.
The changes in steam conditions and the general
operating conditions of the set durinC the second
block start are plotted in Fig. ?. The start was cora-
plete in just over 3 3/4 hours and the general proced-
ure is described. Graphs illustrating the opei-ation
of the turbine driven feed pump are giveri in Fir-. 3.
Simultaneous firin6 of two boilurs gave rise to no
difficulties. Tests results relating to the tvo starz
and the figuit-s relating to heating of the turbines
and boilers are given in Table., 2, temperature- cuxves
for the turbine are given in Fig. 9. There is roa-~on
to suppose that in future the time required for a
block start can if necessary be reduced to 2 1/2 hou--,,s.
It is concltided that the practicability of bloc'.11
starting sets with reheat is fully demonstratod. This
method of starting reduces the starting time, red~ace.-
the temoerature differences and is mach more e-f-l'icien-c
Card 5/8 because steam is no' exhausted to atmosphere. The.
u
boiler firin- conditions are gov~.,rned b-j the conditions

necessary to investigate the conditions of heatin.- and
loading the turbine with reduced steam conditions and
to work out the starting conditions from this.
During the start the greatest temperature differences
in the metal of the set occur at low temperatures ana
proasures, which is whon tho strength of the metal i.,,,
much higher than the design value. Moreover, the
temperature stresses are not then superimposed on
mechanical stresses due to steam pressure. Therefore,
large temperature differences can be permitted in the
early stages of the start. The low thermal stresses
in the furnace and the high rate of steam flow prevent
overheating of the tubes of the main and intermediate
(reheat) radiation superheaters. The set is started
by controlling the firing conditions of the boiler
and this can easily be made automatic. If block

card 6/8 simplified. Therufore, in block uots w% drum type

For re&ular shut-do= of blocks it is advisable
gradually to reduce the intensity of combustion in the

PERIODICAL: Teploenergetika, 1959, Nr 10, pp 49-54 (USSR)
ABSTRACT: Previous articles in Teploenergetika Nr 122, 1957, and
Nr 1, 1958, described the use of shot-blasting to clean
boilers type TP-230-2 at the Omsk Heat and Electric Power
Station when burning fuel oil of high ash, and high
sulphur content. Subsequently the design of the equipment
was improved and it was tried out at a number of power
stations burning anthracite dustq including the NesvetayGREES
(power station)on the Rostov Powez system. When
anthracite dust is burned, heating surfa,:-.es quick.'1y

In the Nesvetay station shot-blasting equipment was
installed on boilers of 110 tons er hour operating at,
steam conditions of 122 ats. and &85 OC. The boilers are

of the convection duct increased by more than 100 mm water
and the outgoing flue gas temperature rose by 25-30 OC.
Typical CUTves showing the increase in re*istance and flue
gas tomperature during a month's operation are given in
Fig 1. The shot-blasting installation was generally
similar to that previously described, but various changes
were made and are described in some detail. Outline
drawings of the modified shot-blasting installation are
given in Fig 2. To reduce losses of shot to atmosphere,
the shot traps were reconstructed, to the form illustrated
in Fig 3. It was found necessary to fit pieces of wire
I mm diameter on the conical shutters at the bottom of the
shot traps so that a certain amount of air could leak
round the shutter and equalise the pressure above it.
The results of pressure measurements using the modified
shutter are plotted in Fig 5. Minor modifications were
Card 2A made to the ash bunkers to prevent loss of shot tvo them,
The shot bunkers were made of conical se(,tion instead of

The resistance to flow was maintained constant throughout
this period and variations in flue gas temperature
.resulted only from variations in feed-water temperatures.
After 45 days' operation with shot-blasting, the
e,.,onomiser and water heater remained clean and ash
depo3its were found only in places not reaohed by the
shot. The loss of shot was about 0.6% of the total
quantity passed and this could be further reduced by
minor design changes. The equipment is reliable and the
main parts may be used for the design of similar

noticeably the n3m-enial properties of the solid solutions. At a frequency of
50 cps) Epsilon Increases with increasing field by more than 200 times, and it
may reach 100,000 at a field E equals 0.6 kv/cm, with the increase of Epsilon
being accompanied by an increase of tg Delta, which goes through a maximum at
approximtely 1 kv/cm with increasing E, eXter which it decreases and reached
0.2. In the region of weak fields, the coefficient of reversible nomeniality of
the single crystals of Ba (Ti Hf) 0 sub 3 is much higher than in solid solutions
Ba (Ti Sn) 0 sub 3. The hysteresis loops of these single crystals are
rectangular and 37each saturation even at fields of 5 kv/cm. An anomaly is
observed in the temperature variation of Sig= for most crystals near the Curie

separates into component parts. The melts solidify in the form of glass.
The major part of the system is occupied by the crystallization surface of
lead metaniobate. Two more phases of the side system PbO -Nb 205 (A and B)

ABSTRACT: Chemically pure (Ba, Pb)TiO 3 solid solutions were prepared from water-
soluble reagents by coprecipitation from titanium tetrachloride, barium chloride, and
lead nitrate solution, and by the exchange reaction between potassium titanyl oxalate
and lead and barium nitrates. The chemical procedures are discussed in some detail
and the properties of the solid solutions are described briefly. Lead titanyl oxalate

tures of lead and barium titanyl oxalates. Zt was not possible so to adjust the PH
as to eliminate this contamination. Lead chloride also precipitated when the synthesis
was performed at 800C by the method of W.S.Clabaugh, E.U.Swiggard, and R.Gilchrist
(J. Res. Natl. Bur. Standards, 56, No. 5, 289 (1956)) and could only be removed
(together with some of the titanyl oxalates) by prolonged washing with hot water.
X-ray studies of the coprecipitated materials clearly showed the formation of tetra-
gonal solid solutions after heating to 8000. The degree of tetragonality decreased
regularly from lead to barium. The resulting chemically pure solid solutions sintered
poorly and it was not possible to obtain dense ter oelectrle navumlwi by Intoring in
0
air at 1100 to 1300 . The Curie point of a ceramic of the composition~14
(Boo.95# Pbo 05)T'03, derived from the temperature dependence of the dielectric
constant at i megacycle/sec, was 1530. This is considerably higher than the approxi-
mately 1400 Curie point usually obtained for ceramics of this composition prepared
from technical grade materials. The increase of the Curie temperature is ascribed to
the purity of the material. The dielectric constant itself was lower than is usually
obtained for ceramics of this composition, owing to the large porosity due to poor
sintering. Orig. art. has: I figure and 3 tables.

ABSTRACT: The paper describes experimentation which revealed a significant
anomaly of the rate of growth on faces (110)'and (001) of crystals of triglycinsulfate
(TGS) in the vicinity of the Curie temperature (T). 'ihe process reported was
studied as a functibn of the supercooling of solutions, the saturation T of which lies
within the 30-600C interval. The Curie T, that is, the T of seigne tte- electrical
phase transformation of TGS lies in the 47-500 interval. The TGS was synthesized
from glycol and concentrated I-12,SO4. The substance obtained was recrystallized 4
times in distilled,water, The test equipment used was'similar to that employed by
G. Bliznakov and Ye. Kirkova (Zeitschr. f. Phys. Chemie, no. 3/4, 1957). The equip-,--
ment consists basically of a saturator in which the solution was saturated-through

the dissolution of small crystals placed on a glass filter*and was then bro(ight into
another vessel in which circulating cold water supersaturated the solution. Crys-
tallization began on a sm.all crystal, 3-4 mm in size, with clearly defined faces,
.which had been fastened on*a holder in such a way that the test face was at the level
of a microscope sighting tube, parallel to the visual ray, and was oriented suitably
relative to the flow lines of the supe'
rsaturated solution (usually parallel thereto).
Micrometric readings were made eyery 4-5 hrs at low degrees of supersaturation
(SS))every 4540 min at elevated degrees of SS'. The rate of change of translation
(RC) of the face (001) as a function of T for various degrees of supercooling grows
up to T close to the Curie T. In the vicinity of that T (in the 35-450 range) the RC
decreases. Above 450 it grows again sharply. The RC of the (110) face behaves
differently: It increases with increasing T up to 46-470, drops slightly in the 47-
500 interval, and then grows again. With more elevated 'degrees of supercooling
the RC anomaly near the Curie T decreases and vanishes completely for a super-
cooling of 1.40C. Orig. art. has 4.figs.

ABSTRACT: The paper describes an experimental investigation of the change in
heat conductivity (HC) and the linear expansion coefficient (LEC) of tri%lycinsulfate
(TGS) along the axes (100 ] , (010] , and (001 ] between 20 and 60 C, a tem-
perature (T) range that comprises the s eigne tte -electrical transformation segment
,Of TGS (47-500C). . Measurements of the HC were performed as follows: Two half-
crystals were fitted together closely along the (001).plane, and a heater wire and a
thermocouple were clamped between them at a distance of 6-7 mm from one
another. HC along the 1100 ) axis was determined by orienting the heater wire

and the thermocouple along the axis [0101 HC along the axis 0 101 was
[100 A j
measured by orienting the two wires along the axis heat pulse was im-
parted by 9nergizing the heater wire, and the change in T, the time required to at-
tain the T maximum, and the maximum-T value were measured. The HC curve vs.
T in the direction [ 100 ] shows a nearly linear decrease up to the Curie point;
above the Curie T,- the decrease continues linearly, but at a smaller slope. The
HC-vs.-T curve in the 'direction [ 0 10] is nearly linear from ZOOG to the Curie
point, rises.to a hump at 50-510, -and then continues with the same slope ~as the
initial segment. These anomalies are attributed to a change in the character of the
.thermal motions of the ions. The measurements of the LEC were performed with
a quartz dilatometer. T steps of 5 to 60 were reduced to 0.4-0.50 in the vicinity of
the Curie T. Hold: ZO-30 min. Specimens were cut from a TGS single crystal in
the form of parallelepipeda 3x3 mm in cross section, 18-Z5 mim long. Specimens
cut along the axes [ 1001 and [0 10 1 exhibit a nonlinp-Ar--decrease- in-length--up t6-
the Curie point and a linear in6reas~ beyond it. The exact opposite occurs with
specimen's cut along the a-$is [001 ) . The results obtained concur with those of
the X-ray tests )y Z. 1. Yozhkiva, et al. (Kris tallografiya, y.1, rio.1, 1956).
Wherever differences are not~_d, such as those in the character of the change of the
LEC along the [ 010 1 axis and some of the differences in the absolute values of
the,LEC, the present testing method is regarded to be more accurate than the

X-ray method. The tensor surfaces of the LEC at 300, 400 and 50'C are drawn
both in cross section and inisometric representation. The isometric images of the
tensor surfaces below and above the Curie point show that at the Curie point there
is not only a rotation of'the surfaces, but also a deformation, as a result of which
increased internal stresses arise in the TGS crystal. Orig. art. has 6 figs.

A13STRACT: The intensity of a number of x-ray rof lections from triglycino. suff ate
was measured at temperatures from 00 to qo0C. Copper M radiation was employed. Af-
ter it was ground to a powder, the sample vias annealed for 24 hours at 700C. The
temperature was held constant to within �0.30Q during mensurement. Thc intensity of
the reflections was determined from the number of counts recorded by i mechanical
counter during the exposure, and n1so from the area under the curie traced by a re-
cording galvanometer. The intensity of some reflections (including (024).and (344))
decreased monoton1cally with Iincreasing temperature over the full range investigabyl.

ACCESSION NR: AP4030640
As regards these reflections, the Curio point was marked only by.an increase in the
scatter of the experimental points. The intensity of other reflections (including
(040) and (031)) reached a pronounced maximum at the Curie point. The different be-
havior of the different lines is ascribed to effects of crystal structure, and par-
ticularly to those of the system of hydrogen bonds. The behavior of the x-ray re-
flections indicates that the atomic vibrations are strongly anisotropic at' the Cur-
io point. This agrees with earlier findings based on measurements of the linear ex-
pansion coefficients and the elastic moduli (N.N.Sirota and V.M.Varilt sh,Sb.Xri t
