X-ray diffraction study shows that, during the metal-coating, an acid-base interaction between the ceramic components Si02, B203 and the oxides of Mo takes place. It is assumed that Si atoms can diffuse preserving their valence bonds; the diffusion is carried out by a tra.,isformation of these bonds between the atoms. To obtain a strong coating, Mo should be fired on in a slightly oxidizing medium where Mo is oxidized to a basic oxide at the ceramic boundary.

Rentgenograficheskiye issledovaniya struktury steatita) PERIODICAL: Izvestiya Vysshikh Uchebnykh Zavedeniy, Fizika, 1958, Nr 4, pp 135-139 (USSR) ABSTRACT: Paper presented at the Inter-University Conference on Dielectrics and Semiconductors, Tomsk, February,1958, In the past much attention has been paid to the physical and technological properties of the manufacture of steatite but too little attention has been given to the microscopic processes, i.e. to structural changes,in spite of the fact that these changes govern the observed changes in properties. The main aim of the here described work was to study the structure and structural changes of vacuum-tiGht ceramics. The process of forming was studied of the crystalline component of various steatite materials which were produced by pressing and also by Cardl/4 casting under pressure in the hot state. First,the structural studies are described of specimens produced by SOV/139- 56--d' -22/3C On the Polymorphism of Steatite Ceramics pressing. In studying the ceramic material VK-92 (B) the lines enumerated in Table 1, P 156, were selecte-a as being the most charact,eristic for each phase under consideration. The changes of the phase composition of this cergic is graphed in Fig.la; it can be seen that up to 350 C tale predominates, then, due to decomDositior of the tale, an intermediate product,hydroenstatite, forms which becomes transformed at more elevated temperatures into Drotoenstatite; the silica which separates out during the decomposition manifests 0itself in the X-ray patterns as christobalite from ~100 0 onwards. Specimens fired above 1250 to 1320 C show a partial transformation of protoenstatite into 0 clinoenstatite but even specimens fired at 1400 C co-.-. In magnesium metasilicate, predominantly in the form of protoenstatite. Magnesium oxide additions between 1 and 6% were tried and also barium oxide additions as well as additions of oxides of alkali metals (1% Na20 or K20). In Table 2 an enumeration is given of the bending strength of specimens from three types of Card2/4 materials produced by casting under pressure and, for On thePolymorphism of Steatite Ceramics SOV/139-58-4-22/30 comparison, the data for the same materials are given if produced by pressing. Some of the results obtained on specimens produced by casting under Dressure in the hot state are graphed in Fig.3 and it can be seen that generally the dependence of the phase composition on the temperature is comparable for all the tested ceramic materials. The determined higher mechanical strength of ceramic materials produced by casting under pressure is attributed to the absence of polymorphous transforma- tions of magnesium metasilicate,due to the stabilisation of protoenstatite and also to the saturation of the glass phase and possibly also of the crystal phase with silica which results in an improvement in the physico-chemical and mechanical properties of the glass phase, which in turn brings about a stabilisation of the protoenstatite. The results are summarised thus: 1) It was found that additions of magnesium oxide bring about a transformation of the protoenstatite into clinoenstatite, whilst BaO. Na 0 and K 0 brake such transformation. This is probibly due 2t0 the change in Card3/4 the composition of the glass phase resulting from the On the Polymorphisia, of Steatite Ceramics SOV/--, simultaneous transformation of the silica into the glasS phase. 2) During firing of cast specimens, a transformation of clinoenstatite into protoenstatite Was observed C), The formed protoenstatite has a higher stability to polymorphism and this can be due to either a partial dissolution of the christobalite into the glass phase, which brings about an increase in viscosity, or formation of a solid solution of silica in the protoenstatite which slows down the process of polymorphous transformation.

(Pribor dlya izmereniya elektroprovodnosti i postoyannoy kholla v ton1kikh sloyakh poluprovodniklov) PERIODICAL: Fribory i Tellchnilv.-a Eksperimenta, 1~57, .00-5, pp. 119-120 (USSR). ABSTRACT: The instrument (Fifr.!) cann be used for raid measurement of electrical conductivity and Hall's constant for --iven areas on thin specimens deposited on slides of rl-lass or other dielectric material. The slide 3 with the deposited samples 4 is kept in position by the cam 2 on a moveable table 1. The table moves on a lath along the guide 7. The fixer 5 kleeps the table and, consequently, also the sample in the require(f positions. A panel 8 on a moveable table has current, compensation and Hall electrodes 6 attached to JLt. This panel is kert in -Dlace by springs 13 and is moved by means of the lever ~ and -cam 10, perpendicularly to the Plane of the specimen, and keeps the direction of motion by means of the four rods 12. The elec- trodes can move freely along the bushes, pressed _i_nto the panel, under the action of bronze sDri-,)E-:s 11. The scheme Produces the uardl/3 -necessary control of contact pressure on the sPec-imen and the 120-5-31/35 An Instrument for the Measurement of Electrical (jonductivIty and Hall's Constant in Thin Semi-conducting Layers. U panel can be raised when the table 1 carrying the soecimen is moved. The simple constructior of the electrodes means that one can have a collection of electrodes eade from different materials and having contact surfaces of different form and size, and that one can deposit on their surface various coatings. When workinft-~ with very thin layers one can put end pieces of soft metal (e.g. indium or tin ) on the ends of the electrodes to protect the layer. The distance between the electrodes on the nanel can be varied deperading on the size of the sample. The samples were deposited an slides 23 x 80 mm in ar a, the surface area of the samnles themselves being 23 x 50 mm~ After the deposition, the latter surface i divided by means of a standard oattern into sections 23 x 4 mm with 6aps of 1 mm between them.- The device is sus- pended between the poles of an electromagnet on tuwo pivots 14, connecting the device with a platform placed on the windings of the electromagnet. Provision is r.,~ade for the control of the position of the device between the poles of the electromagnet. The device lies in a gap of 25 mm between the poles of the electromagnet. Brass was used for the metallic pTts and organic uard2/3glass for insulation. Measurements were carried out (Ref.1) of 120-5-31/35 An Instrument for the Leasurement of Electrical Conductivity and Hall's Constant in Thin Semi-conductinE Layers. the properties of thin layerr.-, of se~)aratue elements obtained by evaporation in a vacuum and also of thin layers of binary speci- mens obtained by Vekshinskiy's method (Ref.2) from elements of group III and V of the periodic table. By a comparison of the distribution of electrical properties along the length of P_ specimen, and the distribution function of concentration of the components calculated frOR! Vekshinskiy's formulae, Lt is possible to obtain the dependence of electric properties on composition in a wide range of concentrations of the binary alloy.

This task imposes the necessity of ensuring the possibility of repetition of -',-he measurements at definite intervals of time, n!aizitainiriL; Lhe a~ubient condiLions con--stant. The solution of these Droblems is oossible if r;echanicallv- strong and stable specimens of ohmic contacts are available. In this paper, a method is described of producinE such con- tacts for specimens which are then fittea into an ampule 200 mm .Long, 20 mr. diav,,,ith 6 external leads. The senuence of Uardl/3 the operations is illustrated by Fig.1, P-115~ It lls based on 12, C M(~~Ih()d of llivesLig~otinL-, the Eiectrical Properties of Thin Layers on an Insulated Base in a Vacuui_ri. cutting off a certain length of the glass ampule, salderiln~, on tile specimen at the bottom of the leads and then replacinC ti-le Cut-off part of the glass ampule which is joine(I to 1U1.e OUrier part of the ampule by applying heat. In t1-_,e case of ti,41'n layers, deposited on oure glass or on pare quartz, this method permits ob~ainin- mec~janically-strong and st-able contacts, To prevent destruction of the thin layer, no solderinj~; flux is used; the molten indium diffuses through the deposited layer and forms a strong bond with I.-he base. After soldering- of the specimen, the cut-off part of the ampule is replaced a~d. joined on by applying heat (Fig.1, d). The fact that the and the contacts are at a distance of 12 to 15 cm from the point of soldering on of the glass prevents their being heated. Following that, the ampule is evacuated and then sealed. The ampules also coritain two thermocouples and two platinum leads, This method was used for investigating the temperature dei~en- dence of the electric properties of thin layers of AlSb, !nSb and GaSb deposited by means of tLe method of S.A.

Function Generators Using Diodes 3 The author states that vacuum-tube or semiconductor diodes may be used in function generator circuits, for which case errors may be as high as 1 to 3 percent, or as low as one-tenth of a percent. When selenium or copper oxide rectifiers are used as diodes, errors will greatly increase. The author emphasizeaq the advantages of diode- equipped function generators ovdr electromechanical ones (potentiometers, rotatable transfo-.:Imers, etc.). These advan- tages consist primarily in the absence of mechanical parts Card 2/6 Computers (Cont.) SOV/1254 and, consequently, in low inertia.

It is pointed out that the ex- periment should be combined correctly with calculations, that physiological data of the operator should be taken into consideration, that human reactions should be expressed as mathematical functions, and that the functions should be introduced into the system equations. As a result of testing models, it is pointed out that tracking errors depend materially on the indicator sensitivity and on the multiplying factor of one revolution of the controller. Sensitivity of fine reading should be of such value that the fine-reading limit is not lower than Card 1/z 112-57-7-14984 Methods of Investigating Semiautomatic Tracking and Regulation Systems the coarse-reading error. Reduction of the one-revolution multiplier of the controller is limited by the permissible speed of flywheel rotation.

The Ural-4 was used to work out technological processes for creating parts identical to those from which it was made. Having obtained the program, the Ural-4 models the intellectilal activity of a highly qualified technologist. After about 1.5 minutes, the machine starts to deliver the projected technological diagram, which contains all the data for making the parts. The conn,uter reduced the time of preparing the technological documentation by 5-6 times and halved the cost. SUB CODE: 09 / SUBM DATE: none / ATD PRESS: 5113 Card 1/1 PRFSNYAKOV, A.

Shtraus operating with ten- zion velocities as high as 1.25; 4; 20; 78; ciOlt; and 960 mm/min. The tests were carried out at 20, 40, 65, 90, 115, 14o, 155, 1065 and 1300C. Maxi- mum indices of super-ductility attaining 425%; are obtained at 4 mm/min tension velocity. Elongation approaching this value takes place at 20 mm.1min. At all the other, higher or lovier, velocities, ductility indices do not exceed 2501%. At 90SO mm/min tension velocity, maximum elongation is not over 8552. The duc- tility maximum varies with temperature. At 1.25 mm/min tension velocity, i~ ts located at about 1750C.

PERIODICAL: "Metallovedenie i Obrabotka Metalloy" (MletallurE d Metal Treatment), 1957, Ro-5, PP-53-55 (U.S.S.R ~ an ABSTRACT: The influence of low melting point admixtures, for in.stance of lead, on0reducing the plasticity of certain alloys at 500 to 700 C and subsequent sharp increase at higher temperatures is not dealt with sufficiently in literature. The changes in the plasticity of brass was investigated in presence of Fb and Sb for brasses of the chemical compositions as enumerated in Table 1, P-53 (about 6W6 Cu, impurities of Fe, Pb and Sb, rest Zn). The plasticity was defined as the relative contraction of the cross section of the specimens during dynamic stretching. The obtained data as a function of the Pb and Sb contEnts valid for various temperatures between 20 and 850 C are silmmarised in Tables 2 and 3, P-53. It was found that durinE the shaping process contaminated L62 brass should not be allowed to cool down during the process of deformation to temperatures corresponding to the temperatures of brittleness formation, i.e. -that the shaping should be carried out at hiLter temperatures than for brass with- out any contaminations. 3 Tables, 8 Russian references. !t AUTHOR: -Presnyakov, A.A., Candidate of Technical Sciences.

The "coefficient of relative alloying", X, is taken as a characteristic of the chemical composition of solid solutions: X = 100 x C1/Csat. (C - concentration of the second component in the solid solution; Csat. - maximum concentration in the saturated solid solution), X being also a function of the temperature. The 6raph, Fig.1, gives date on the ductility of steels with various degrees of alloying as a function of the temperature on the basis of the data given by Zuyev,M.I. et alii (8); most of the alloys have high ductility indices at elevated temperatures and the higher the degree of alloying with carbon, the greater Is the drop in ductility at tempera- tures above 0.6 Tfus.abs.'

Fig.3 shows the change in ductility of copper- nickel alloys of various degrees of alloying on the basis of literary data and the results of the author himself and Fi6.4 shows the same relation for the ductility of certain nickel alloys. More complex (ternary, quaternary) alloys show lower ductility than binary ones.

The obtained results also provide an explanation for the formation of a zone of brittleness of brasses in the temperature range 400 to 700 C; this is attributed to the influence of certain distortions of the crystal lattice.

PERIODICAL: Zavodskaya Laboratoriya, 1957, Vol. 23, Nr 12, pp. 1515-1515 (USSR) ABSTRACT: In the introduction it is said that the results of measurements carried out -;rlth thermocouples often do not agree, which can mostly be explained by the fact that the sample and the thermocouple in the respective case do not possess the same optical properties. For reasons of the precise definiticn of a nwber of experimental data concerning aluminum- and zinc alloys, a uniform investigation of these materials was carried out. For this purpose a differential- nichrome constantan thermocouple, made of a veire of 0.30 mm thick- ness, and a round nichrome electric furnace was used. Between the sample and the heater a nickel screen %ms fitted in orier to attain uniform heating of the sample.

Experiments show that in the case of a heating lasting up to 20 minutes no definite equalization of temper- ature between the sairmle and the thennocouple could be attained, so that in aluminum alloys differences of 6-8% were observed in re- sults. A checking of data concerning zinc allo *- showed still higher results.

Receiveds 4 / 1957 Revieweds 5 / 1957 ABSTRACT: The diffusion of sulphur in nickel was investigated and data con- cerning the influence of deformation on the diffusion velocity of the element concerned were collected. The working method is de- scribed, for which purpose the depth of the layer d, which is affected by sulphur, served as a measure for diffusion velocity. The structure observed confirms the opinion of some authors concern- ing the solubility of sulphur in nickel. From the analysis carried out it may be concluded that with an increased amount of the previous cold deformation the diffusion ot sulphur in nickel can be suppressed. The experimental data obtained by the author are in contrumft&tion to the opinion expressed in published works con- cerning the rules governing "a considerable increase of diffusion velccity in bodies with a distorted lattice,,. The anthor is of the opinion that the distortion of the lattice exercises influence on the diffusion velocity, but that in some cases it may also slow down the diffusion process.

The rate of diffusion of sulphur into nickel was fSund to depend on temperature becoming appreciable at 500 C; the rate decreases witL increasing degree of preliminary deformation. A photomicrograph of deformed nickel with a sulphur-saturated surface layer is shown and graphs of thickness of sulphur- affected layer vs time and vs degree of deformation ai-e given.
