(Translated from Reforativn)-y Zhurnal Khimiya, No 4, Moscow, 1972, Abstract No 4L245 from the resume). Translation: A device is patented for distribution of amalgam in scrubber separators, consisting of a perforated grid with a circular tip, separating the upper plane of the grid into central and peripheral zones with apertures for distribution oil the amalgam and output of hydrogen., differing in that in order to improve the flow of amalgam,~eliminate wear of the fitting and prevent hydraulic shock, the apertures in the peripheral zone are made in the form of slits covered with a screen, while the apertures for passage of amalgam are located at the points of intersection of slots made on the lower plane of the grid and forming projections, preventing blockage of the aper- tures with granules of the packing.

"Incubation Period of kydrogen Corrosion of Carbon Steel" Moscow, Zashchita Metallov, Vol 6, No 6, Nov-Dec 70, pp 735-737 Abstract: This article contains the results of a study of the incubation period of hydrogen corrosion of carbon steel. From the data on the variation of the density of steel 45 as a function of the time under the effect of hydrogen and also the distribution of the relative carbon content in~UlOA steel after holding in hydrogen for 6, 10, caid lit hours it is; concluded that the,time before the beginning of hydrogen corrosion is' llt-21 hours, which agrees satisfactorily irith the results calculated by the earlier derived empiricaLequation. The mechzdsm of the extremal nature of the change in density 4pas a,function of the holding time in hydrogen is discussed. During a 14-hour period the processes of shrink- age and swelling of the steel develop predominately in the thin surface layer. Ho-wever, 'wilea holding for 21 hours the swelling not only greatly exceeds the contraction but it also extends to a significant depth.' It is concluded that the incubation period of lVdrogen corrosion can be subdivided into two steps. In the first step there is surface decarburization 1/2 USSR ALFXSE-M, V. I., et al., Zashchita Metallov, Vol 6, No 6, Nov-Dec 70, PP 735-737 and accirmullation of net'fiane Ln the micropores of the st.eel to pressures leading to small, probably elastic deformation of the matrix. The plastic properties of the steel practically do not change. On i~eaching the critical pressure, intense growth of the pores begins, controlled, probably, by the laws of elasticity and plasticity and also by the rate of methane accumulation in the micropores. The plastic properties of the steel become worse, and this is considered the second step.-of the incubation period. As a result of,grow-th:and merging of the micro- pores, microcracks are formed, increasing the hydrogen~penetrability of the steel and its contact surface with the hydrogen atmosphere, leading to sharply intensi- fied dscarburization. Thus, the swelling of steel h5 after holding in hydrogen at 500 and 100 technicaJ. atmospheres up to 1h hours is but holding it for 21 hours leads to a significant decrease in 'density and plasticity. This can be related to reaching the critical methane preaswe in the pores during this tine, leading to accelerated crack development and.decarburization. 2/2 k,l UNCLASSIFIED PROCESSING DATE--230CT70 /2 024 ROGEN WITH STEEL KH18'iqlOT AT INTERACT ION OF HYG INCREASED ~!,:':.--TEMPERATURES AND PRESSURES -U- ,:.:AUTHOR-(02)-ARCHAKOV, YU.I., ZARETSKAYA, L.V.

A method i-q described for study- ing fusible heat indicators which allows the temperature and temperature in- terval of melting of the temperature indicators to be determined as a func- tion of pressure and heating rate. The rate of sublimation of the tempera - ture indicators is determined at various pressures. The use of this method has allowed the All-Union Scientific Re5earch Institute of" Luminoplio-i-s and high-purity substances to develop fusible temperature indicators suitable for investigation of heat transfer to flight vehicle models.

DETERMINATION Of: THE ACTIVATION .&NERGY IN THE SINTERING PROCESS OF POROUS PREFORMS OF TITANIUM POWDER WITH PARTICLE 01MENSIONS OF ABOUT 10 MICRONS. IT IS FOUND THAT THE SINTERING PROCESS PROCEEDS IN Two DISTINCT STAGES: (1) UNSTEAOY STAGE WITH A'HIGH COMPACTION RATE AND.(2) STEADY STATE STAGE URfNG WHICH COMPACTION RATE IS DEPENDENT ON THE VOLUME DIFFUSION. LOW VALUES OF THE ACTIVATION ENERGY DURING THE FIRST COMPACTION STAGE ARE SUGGESTED To BE DUE TO THE SOLUTION OF OX!(3ES INTHE SURFACE LAYER OF TITANIUM PARTICLES. UNCLASSIFIED
