Heat treatment for superalloy |
摘要 |
A cobalt-free nickel-base superalloy composed of in weight % 15 Cr-5 Mo-3.5 Ti-4 Al-0.07 (max) C-remainder Ni is given a modified heat treatment. With this heat treatment the cobalt-free alloy achieves certain of the mechanical properties of the corresponding cobalt-containing nickel-base superalloy at 1200 DEG F. (650 DEG C.). Thus strategic cobalt can be replaced with nickel in the superalloy.
