When the Guinier-Preston zones combine with the surrounding matrix, a mixing of atoms occurs in the matrix which..can be re- presented as an elastic shift in the [3_103.planes in the [1101 direction. These shifts- produce I'monoclinic" changes in the initial cubic lattice. A metastable phase occurs .in the alloys when the time lag increases or the hardening temperature rises to 3000C (for Cu-Be) and 5000C (for Ni-Be) due to an extension of the Guinier-Preston zone. The sti7u~qtural relationship between the metastable phase and the solid solution is similar io_.thatbetween ordered and unordered phases in the ordering of an AuCu alloy. The -N ACc - NR,... AR601366 !1motoclinic" changes in the matrix with the aging of Ni-Be and Cu-Be alloys are do,- to the character of the stress state in submicrovolumes of the alloy and to the ani- sotropy of -the elastic constants of the cubic matrix. Large elastic distortions (stresses) with the aging of Ni-Be and Cu-Be alloys do not considerable increase the hardness. The hardness increases only at the stage at which these stresses begin a turn in the blocks of the matrix solid solution. 30 references. I. Tulupova.

After a five-hour tempering period at 200C single cry- stals of Cu-2% Be specimens were submitted to X-ray analysis. Length.and arrangement of diffusion rods along the planes and the region of anomalous scattering were investigated. Some rods were not centrosymmetrical.

At a later stap of aging, the dislocation of atomic planes Lioij towards U011by means of 'r causes the transformation of the cubic lattice into a "monoolinic" lattice. The value of the dislocation is equal i to a minimum of �50 which corresponds to r- 0.1. In aging Al-Cu specimens Guinier-Preston zones are also identified. However, mono-: clinic distortions were not observed. charac-1 The difference in the ter of the matrix distortion in Al-Cu, Cu-Be and Ni-Be specimens was due to different elastic properties of the solid solution.

TITLE: Comparison of X-ray and electron-diffractlon data on the size of crystal blocks in deformed stainless steel And nickel PERIODICAL: Fizika metallov i metallovedeniye, v.14, no.1, 1962, 85-91 TEXT: In X-ray diffraction determinations of the size of crystal blocks with the aid of analysis of the width or form of interference lines the size referred to is that of "regions of coherent L;catterlngff. The question arises as to whether this characterises a dimension of the crystal structuxle or is associated with an optical effect. To solve this problem the authors have compared X-ray results with those of electron microdiffraction from thin foils of the test samples, simultaneous electron-microscopic investigation of these foils being carried out. The samples studied were of an 18-8 type stainless steel and pure nickel, subjecte*d to cold-rolling with 96% reduction combined with heat treatment and, where appropriate, electrolytic thinning. Some Card 1/2 Comparison of X-ray and .electron- S/126/62/ol4/001/007/ol8 Elll/E135 electron micros-copic pictures (generally at 15000 magnification) were also obtained. The authors conclude that, allowing for svstematic errors, the block-size determinations by electron- and X-ray diffraction give practically the same values.. The greatest difference is with nickel, probably because the foil thickness could not be determined with sufficient accuracy. Thus, for deformed stainless steel and pure nickel the dimensions of coherent-scattering regions found from measurements of X-ray interference-line width determination correspond to dimensions of real crystal blocks having a relatively correct internal structure and disorientated relative to each other.

TITLE- Study of the changes in crystal structure of nickel- beryllium alloys in the early stages of ageing PERIODICAL: Kristallograf iya, 1961, voi. 6, No. 4, PP - 560-567 + 3 Plates TEXT: Single crystals of Ni-Be alloys containing 2.2% Be were quenc~hed from 11000C and aged at 425 or 5000C. The change in hardness (Rockwell B) with the total soaking time during tempering (in minutes and hours) is shown in Fig.l. The alloys were studied by X-ray analysis to elucidate the changes in structure. In the early stages of ageing (30 min to 2 hours at 4259C) the formation of Guinier-Preston zones considerably enriched in beryllium occurs. They are in a plate-form of 1 to 2 atomic layers thick and parallel to the (100) planes in the matrix. At the same time all the solid solution is less-rich in beryllium and approaches to the equilibrium state. The depleted matrix divides Into separate blocks which at first have different orientations one from another. The blocks are elastically distorted. There are cracks with thickness of the order of 20 to 30 A in the matrix Card 1/3 25892 S/07o/6i/oo6/oo4/oo4/o07 Study of the changes in crystal ... E02l/E4o6 along the (110) planes. At 500*C, the G.P. zones increase in size, regions with structure close to P phase appear and orientated rotation of the blocks occurs around one axis of the CILOO] type. This rotation reaches 8 to 100 after 32 hours at 5000C. The high hardness values of aged Ni-Be alloys is connected not with elastic distortion in the matrix but, in the main, with the division of the matrix into blocks and with their rotation relative to one another. All the observed changes result from the large difference in atomic volumes of the matrix and the precipitating phase (NiBe) which reaches 20%.

Thus, the tetragonal structure was not caused by metastable Ni 3Ti compound, as has been proposed (Refs. 3; 7), When the precipitate of the hexagonal q-phase Ni 3Ti first appears, the regions of bcth types became tetragonal with the above axial ratios, The c-axes of all the regions were in the same direction so that the initial monocrystal as a whole appeared to be tetragonal, As precipitation of' the hexagonal phase occurred, recrystallisation of the ,gions poor in titanium also o1ccurred, which resulted in part or the whole of the monocrystal becoming Ca.id 2/4 67W S/07o/60/005/oo6/oo3/ooq E021/E306 Additional Structural Data on the Decomposition of Super- saturated Solid Solutions of Titanium in Nickel and Nichrome polycrystalline.

MGU, 1949, No 3). The use of a balanced method for the measurement of the elec,2. tric quantities made it possible to bring the accuracy of measurement of X to 3%,. and that of x to 1%. Alloys of Card 1/3 USSR/Statistical Physics - Heat D-4 Abs Jour Ref Zhur - Fizika, No 5, 1957, 11455 22 different concentrations were investigated at temperqtu- res to 2420. The alloys with a lead concentration up to 33.67% have (at various temperature ranges for various con- centrations) a positive temperature coefficient at a value of ;,Lless than that of pure bismuth. These phenomena are explained by the presence of a solid solution of lead in the bismuth, and obviously, by the presence of an o,% phase. The dependence of N on the temperature differs from the dependence of ~C on the temperature, this being explained by the heat transfer not only the electrons, but also by the lattice. Assuming that for the electronic portion of the conduction the Wiedemann-Franz law is valid, the au- thors have subdivided the obtained values of ;~ into A ell vhich in pure metals diminishes, and increases in alloys, an0lat, 'which always diminishes with increasing tempera- ture. However, this separation leads to the conclusions that A lat predominates over A ell and consequently Card 2/3 USSR/Statistical Physics - Heat D-4 Abs Jour Ref Zhur - Fizika, No 5, J-957, 11455 doubt is expressed concerning the applicability of the Wiedemann-Franz law for this system. The experimental values of are in good agreement with the equation >-%IC - A � B/T, where A and B are constants, C is the atomic heat capacity, T the absolute temperature. C was measured by the method of cooling in a Torovskiy-Bartenev type setup. A slow increase in C of lead and bismuth with increasing temperature was obtained. The isotherm of C has a minimum at 4.82% and a maximum at 65.70~ lead. This can be explained by the influence of the V~, phase for small concentrations of lead and of the P phase for large concentrations of lead (C of the ck, phase is smaller than C of lead and bismuth, and that of the F phase is greater.)

The present investi- gation was aimed at determining the influence of the.compensating impurity on the ionization energy of the impurity conductivi-kity of the upper acceptor level (for non- hydrogenlike centers). To this end, temperature measurements were made of the car- rier density and the electric conductivity in the temperature faterval 300 - 55K. The procedure far obtaining the samples and of the temperature measurements was de- scribed in the earlier paper. The results show that for most samples the carrier density depends exponentially on the reciprocal temperature. The ionization energy. of these samples at higher temperatures is calculated and the values are listed in a table. An ana3.ysis of the temperature dependence of the Hall mobility has shown I that-,at-low.temperatures scattering of the carriers by charge centers predominates. .Card- ACC NRt AP6036999 The densities of the beryllium and of the phosphorus calculated from there data are also listed. In spite of the fact that the ionization energies were obtained for samples with different acceptor densities, the dependence of the ionization energy of the impurity conductivity on the concentration of the donor impurity agrees well with the standard theoretical formula. It is proposed on this basis that. the change of the ionization energy occurring with increasing donor density is due to the action of the negatively sing2y-charged acceptors. At higher temperatures~ the ionization energy is a'function,of the temperature, this being due,-to a reduction in the screen- ing of the acceptors. The author thanks V. S. Vavilov,.N. A.

The compensating im- :purity was phosphorus. The plates were cut from the ingot perpen- " '4 tdicular to the (1111 crystal growth axis. The measurements were ~mZe in a double metallic cryostat. A null method was used with a C., d .1/4 ACCESSION NR: AP4041733 'high-resistance potentiometer. The magnetic field reached 4600 Oe. -Eight samples from four ingots were tested. The results show that in all samples the carrier density is exponential in the reciprocal temperature.

As Li in Ge has a diffusion coef- ficient of D=1.10 cm2 /sec at 5000C, diffusion of Li into Ge at elevated temperature is the best method of introducing lithium. The germanium specimens were ground, etched, purified, and annealed in vauo at 4900C for 4-8 hrs, depending on the size of the specimen. The annealing was done with an Li-Fb alloy, from which Li diffused into Ge. Starting materials were p-type and n-type germanium having a resistivity of Card 1/3 A 87916 Electrical Conductivity of Lithium-doped 3/181/60/002/012/010'/018 Germanium at Low Temperatures B006/BO63 -50 ohm.cm. The specimens were cut perpendicularly to the growth ax's 11113 , and had a size of 3-4-15 mm. After the diffusion, the specimens were ground anew and etched with boiline H202' Lj-Pb spots were left. a3 contacts. Lithium concentration varied from 2.3-1014 and 2.9-1015 cm-3i resistivity at 3000K from 6.5 to 0.58 ohm.cm, and ionization energy from 9.3 to 9.4 kev. The Hall constant (R) and the variation of resi3tivity under the action of a magnetic field were measured as well. This was done in liquid helium; the temperature of the specimens was determined from the saturation pressure. The measurements in the magnetic field were made a+ 1200 oe; the electric field inside the specimens did not exceed 0.2 -.,/CM and thus remained within the range of validity of Ohm's law. Th,~ curves 9 = f(I/t) and R = f(I/T) are reproduced here. They show that only specimens with 6.5 and 4.45 ohm.cm and lithium ecncentrationo of (2.3-3.9).1014CM-3 have regular (exponential) functio!Ls, wh~-reas specimens with higher lithium concentrations und resi=" + an anzmalous temperature dependence of ? and R, R(1/T) curves, for -xample, have peaks.

The kinetics of interaction of the oxidized silicon surfdCCS with fluo- rine and hydrogen fluoride was studied atr M temperature using the microbalance fi technique.41The object of the work was t fi7l the gap in the pertinent literature. 4e 'Samples of silicon n-type single crystal here cut out along the 111-plane, polished, ei-ched with a IINCV-HF mixture, and washed with double distIlled water. 3- The surface of the silicon samples was oxidized either by treatment with dry oxygen Card 1/2 UDC: 541.124/.128 L 36440-66 ACC NR: AP6018070 CD ,at 11000C (oxide layer thickness 0.15-0.20 v) or treatment with steam in argon at ;,12000C (oxide layer thickness 1-2 p). Fluorine pressures varied from 11 to 44 mm Hg and the EF pressure was less than 100 mm Hg. In the range up to 0.5 g, the accuracy iof the microbalance measurements were approximately 1.8-2xlO-6 g. Prior to treat- ment with Hr, samples of oxidized silicon were treated with fluorine. The depend- ence of the removal of the oxide layer from the silic6n surface upon the duration of ithe HF treatments is graphed. In the case of surface oxidation with dry oxygen, with fluorine had very small effect on the rate of oxide removal by pretreatment treatment with HF. In the case of surface oxidized with steam in argon, :the average rate of oxide removal was 0.04.10-6 g/CM2imin in the case of pretreat- ,ment with fluorine and 12.10-6 g/cm-min without such pretreatment. The effect of ,the. pretreatment with fluorine is traced to the removal of moisture from the oxide .layer.

TITLEs The Composition and Y!"eTa'of XyloleA a By-Product of the Coal Carbonization Process PERIODICALt Koks i khimiya, 1960, No.8, PP-41-44 TEXT: The composition of technical xylole, a by-product of the coal carbonization process, was little investigated, mainly due to lack of reliable methods and the lack of demand for the individual isomers. In the paper, the yield and composition of xylole produced on 9 coking works was investigated using mean dynamic samples for the fourth quarter of 1957. In addition to xylole fraction a part of xylole remains in heavy benzole and solvent naphtha; it was therefore necessary to determine the content of xylole in the above two products (Table 1). The determination of the xylole content was done by careful rectificationusing a column equivalent to 30 theoretical plates at reflux ratio of 5-6. whereupon the fraction boiling at 135.0 to 144-5*C was considered as xylole. The distribution of xylole between the individual products was found to be as followst 78.8% pure xylole fraction Card 1/3 S/068-x/60/000/008/001/003 E071/E435 The Composition and Yield of Xylole, a By-Product of the Coal Carbonization Process (GOST io465-39), 13.1% solvent naphtha (GOST 1923-50) and 8.1% heavy benzole. The content of the individual isomers in technical xylole as well as in xylole separated from solvent naphtha and heavy benzole was determined by the spectrophotometric method. In addition, paraxylole was determined cryostopically and wethaxylole was determined by the usual method through trinitromethaxylole. Non-aromatic admixtures (paraffins and naphthenes) were determined spectrophotometrically (the difference between 100 and the sum of determined aromatics) and by the usual method; sulphonation with 98% sulphuric acid (at 200 for 20 min). The zontent of toluol was determined by rectification. The composition of xyloles from the individual works was found to be similar and is given in Table 2. on the averagc-, the composition of technical xylole was as follows, in % a ethylbenzene 4.8; paraxylene 21.1; methaxylene 58.0; orthoxylene 13.5; t-oluene 1.1~1; non-aromatic and other admixtures 1.3. The composition of xyloles separated from solvent naphtha and heavy benzole was, on average, as follows~. 3.6% ethylben-zenei Card 2/3 S/O68-.v/6O/0OO/Oo8/ool/O03 E071/E435 The ComposItion and Yield of Xylole, a By-Product of the Coal Carbonization Pr cess 16-5% paraxylene; 48.5% methaxylene; 28.5% orthoxylene; 2.9% unsaturated and other admixtures (for individual work see Table 3). The average overall composition of xylole was: 4-5% ethylbenzene; 20.1% paraxylene; 56% methaxylene; 17% orthoxylene; 2.4% unsaturated and other admixtures; it differs from the equilibrium composition (given in Table 4).

An investigation was carried out in order to study the process of purification of benzole-toluole fracti L up to the limits required for the benzole synthesis I and to develop the optimum scheme for the production of such benzole. The investigation of the appropriate fractions from Zaporozhe T and Bagleysk Coke Oven 470 rks (Table 1) under laboratory conditions was carried out. At first 7 a direct Tuiashing of the whole fractions was tested (Table 2); the results obtained indicated that this method of purification is unprofitable. Therefore, the following investigations were carried out: 1) Separation of BTX (mixed) fraction into a narrow benzole fraction and a toluole-xylole fraction with their subsequent treatment to a --equired purity; 2) The usual washing of mixed fraction to limits required to obtain pure products Uardl/2 68-58-2-10/21 Production of High-qual-ity Benzole for Organic Synthesis (bromine numbers benzoleAKO.6- toluole
