IMPROVEMENTS IN OR RELATING TO THE HEAT TREATMENT OF ZIRCONIUM ALLOYS
Patent
·
OSTI ID:4257172
A heat treatment to improve creep resistance of Zr alloys by decomposing the 6 wt.% Ru-U all phase is offered. Alloys of Zr with either 7.5 wt.% Mo, or 10 wt.% Nb, or 6.7 wt. % Sn, or 1.5 wt.% Al are homogenized in a vacuum furnace at 1100 C and, after cold-working, aged at 600 C 300 hours. Improvement in creep resistance is noted for the Mo and Nb alloys. (T.R.H.)
