Change of tin atoms state in Zr alloys in the process of heat treatment

摘要

By means of Mossbauer spectroscopy, the data on tin atoms states in zirconium Zr-1.21Fe-1.31Sn and Zr-0.69Fe-1,35Sn-0,88Nb alloys quenched from beta-region and subsequently annealed at 350 deg C have been obtained. After annealing, beta-Sn precipitates are found in specimens of the ternary alloy, and formations of Nb_3Sn compound is probably in the specimens of fourcomponents alloy. During annealing, tin atoms pass in a solid solution of alpha-Zr.
