Procedures for Avoiding Heat-Treat Cracking in Nickel-Base Superalloy Weldments. Part 2

Abstract

The program concerned the development of procedures for avoiding post-weld heat-treat cracking in nickel-base superalloy weldments. Crack- susceptibility data were obtained for a number of studies including the effects of varying preweld solutioning treatments, effects of pre-weld cold work, effects of oxidation damage due to inadequate shielding during welding, evaluation of Rene' 41 powder metallurgy sheet material, procedure verifications, and the evaluation of varying pre-weld base metal heat treatments for avoiding heat-treat cracking in Astroloy.
