Abstract

A process for homogenizing zirconium alloys and minimizing metallurgical effects of certain alloy and impurity segregates, including tin-rich segregates. The zirconium alloys are heated to high temperatures for sufficient time to cause the tin-rich stringers or segregates to homogenize in the zirconium alloys. The temperature of treatment is above 1000 DEG C, and is related to the time of treatment by [Temperature in DEG C] >/= 1225-70 loge[Time in hours] An examplary composition by weight is:- Sn trace to 3% Fe trace to 0.3% Cr trace to 0.15% Ni trace to 0.1% C trace to 0.05% Si trace to 0.03% Zr Balance <IMAGE>
