Title: Highly corrosion-resistant zirconium alloy
Inventor: HIGASHINAKAGAHA EMIKO
IPC: C22C16/00
Filed: 1986-10-17
Abstract: PURPOSE:To improve nodular corrosion resistance by limiting respective amounts of Zr as a precipitate in a grain boundary and in a grain and Sn in an intermetallic compound as an additive element in a zirconium-base alloy in which amounts of Sn and Fe are specified. CONSTITUTION:The zirconium-based alloy containing, by weight, 0.5-3.0% Sn and 0.07-0.6% Fe and also containing, besides the above, at least one kind among <=0.5% Ni, <=0.2% Cr, and <=2.0% Nb, where the amount of Zr as a precipitate dispersed or existing in chain condition in a grain boundary and in a grain and the amount of Sn in an intermetallic compound as an additive element are regulated to <4.0%, respectively, is refined. Subsequently, this alloy is passed through the stages of hot forging, solution heat treatment, hot rolling, cold rolling, annealing, etc., so as to be formed into the desired shape. This highly corrosion-resistant zirconium alloy is improved in nodular corrosion resistance since Sn is not concentrated in the precipitate existing in the grain boundary and in the grain.
