In this paper, the diffusion coefficients of the ~(14)C in austenite of armco iron specimens vari-ously cold deformed were investigated by using the radioisotope technique, and it was autora-diographed on the carburization surface layer.

• 采用放射性同位素技术测定了在渗~(14)C过程中~(14)C在不同量室温形变工业纯铁奥氏体中的扩散系数,并对渗层进行自射线照相。
