Description
なお、これまでに開発された超合金(Ni基超合金含む)全般に関する、力学特性、合金組成、組織形態などに関する基礎的な技術については、C.T.Simsによって知られている(C.T. Sims and W.C. Hagel, The superalloys, John wiley and sons, Toronto, 1972.)。また、超合金の中でも、特にFCCをベースとしD0 22 構造を有するNi3Nb(γ''相)を強化相とした、Inconel 718系合金に関する技術が知られている(Superalloys 718, 625, 706 and various derivatives : proceedings of the International Symposium on Superalloys 718, 625, 706 andVarious Derivatives, held June 26-29, 1994 / edited by Edward A. Loria)。
