Korrosionsbeständige Nickel-Chrom-Molybdän-Legierungen

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...

More Information
Summary: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, low carbon and a titanium to carbon ratio greater than 1 which is particularly adapted to be effectively treated by the homogenization heat treatment. The single or two staged homogenization takes place from 1141 DEG C to 1316 DEG C for a period of at least 5 hours.
