G, Af-anaslyeva). The specimen was heated non-uniformly along the length so that the maximum temperature was reached in the middle where the hot Joint of the thermocouple was welded on. The points analysed by spectrum analysis were spaced at 2.5 mm. beginning from the middle of the specimen. The spectral determination was repoated three times at points of equal distance from the coatre of the specimen and,,according to calibration temperature curves I 4'he temperiture was determined which was maintained in the specimen at the level of each of the analysed points. This enabled determining the dependence of the residual concentration of the analysed elements as a function of the heatin temperature for a 9 givenheating duration. On the basis of the resultsl which are described, graphed and discussed, the following Card 2/6 conclusions.are arrived at:l)heating in vacuum of multi- SOV/126-6-1-21/3 13 -On the Selective Ii,-,rap oration of Certain Metals fro= a -Surf ace- During-Heating -in-- Vacwjm- component metallic alloys, and particularly of alloy ,steel, is accompanied by selective evaporation of metals, as a result of vi enitial composition of the surface layer of the metal changes appreciably. 2) Of the five elements under consideration (Mn, Or, Fe> Nt5 rilo) Mn hao the highent iricAination to OVAPOMI;Q,~Jft t1v) tom 0 wj~j'.Vo Uro rumro 700-1200 0 at 0.

The change in the composition of the surface layer of alloy steel as a result of evaporation is accompanied by appreciable changes in its properties, particularly, by intensive changes in the resistance to corrosion; the effect of these changes is determined by the volatility of the alloying elements and their influence on the respective properties of the steel. 6. Data on the change of the composition of the surface of the steel during the process of evaporation enablea establishing the composition of the vapour which separates out from the steel surface,provided that the system contains at least one element which does not part ic ipa-' te in the evaporation or an element for whidh the degree of evaporation is known. 7. Application of numerous vacuum instruments for investigating the structure and the proparties of metDIs at elevated temperatures is inadmissible without taking 1-ion of into consideration the variability of the composit Card 4/6- the surface of-the metal-during the tests. In the case SOV/126-6-1-21/33 On the Selective Evaporation of Certain Metals from a Steel Surface During Heating in Vacuum of multi-component systems, application of such instruments should be strictly limited as regards the permissible temperatures and for short durations so as to ensure relative constancy of the composition and the properties of the metallic surface. In absence of such limitations, utilisation of results of anisometric, dilatometric, durometrie, magnetic and electric measure- ments, and particularly of micro-structural observations, at elevated temperatures under high vacuum involves greater or lesser errors due to the fact that the results of the measurements will no longer apply to an alloy of' the initial compositioa.

The vapor pressure at various temperatures was determined by the loss-of-weight method during an48 hours' heating. At 200 C the vapor pressure amounts to 2.10 mia of mercurj colama. A protracted degassing of polymerized resins leads to a cessation of gas separation (the loss of-weight was not determined). After the resin had been degaqsed at 1500 C a mass spectrogram was recorded at 1000 C. No peaks distinctive of the resin ware found in this connection. The maes-spootrographioal measurements ware carried out by Ya.A. Yukhvidin. In the course of the in7eatigations it was substantiated that epoxide resins after polymerization are vacuum resistant-materials. The ezoallant adhesion properties of the resins make possible a production of high-vacuum joints with glass and with various other materials.

This idea has been taken up by B. Ya. Moyzhes and G. Ye. Pikus, who have developed a theory of gaseous semiconductors. For a verification of this theory, the author of the paper under consideration has conducted tests whose 'Pre- liminary results are published here. The author worked out a device with a cylindrical cathode and a molybdenum anode; the cathode was heated by electron bombardment, the temperature being measured by an optical pyro- meter. The anode temperature did not exceed 8000K, while that of the cathode ranged between 1100 and 22001K-, Cesium vapor was introduced in the Interelectrode spacing.
