A homogenization heat treatment minimizes the formation of Mu phase in nickel-base alloys of high combined percentages of chromium, e.g., 19 to 25% and molybdenum,. e.g., 12 to 18% particularly together with tungsten. Also described is an advantageous alloy composition containing less than 2.5% iron...
