Diffusion in Heat-Resisting Alloys of Cobalt Base(Diffuziya v Zharoprochnykh Splavakh na Kobavakh na Kobal'tovoi Oshove)

摘要

The diffusion of radioactive Co, Cr, and W into a variety of alloys (containing principally Ni, Cr, Co, W, Mo, and minor amounts of C, Si, Mn, Fe, S, P, and Al) were measured in the temperature range of 850 to 1250C. Gruzin's method of measuring residual activity was the experimental technique used. Arrhenius plots are presented and the parameters of the diffusion equations listed. The role of carbide growth occurring in these alloys is discussed. The effect of various alloying elements (C and Mo) on the diffusion constants was also studied.
