Abstract
A nickel base superalloy, having either columnar or equiaxed grain structure, which has significantly improved resistance to hydrogen embrittlement, and to fatigue in air. The material is processed so as to be essentially free of script type carbides, .gamma./.gamma.' eutectic islands and porosity. The processing includes heat treating above the .gamma.' solvus temperature to solution the script type carbides and eutectic islands, followed by HIP to eliminate the porosity.
