The morphology of associated precipitation and compactmorphology of γ′+γ″ were obtained by modifying the contents of Al, Ti and Nb. Experimen-tal results show that the compact morphology of γ′+γ″ has the best thermal structure stability.Instead of γ″ transformation in Inconel 718 the dissolution of strengthening phases in modi-fied alloy leads material degradation. Key words:  Inconel 718      thermal structure stability      associated precipitate      compact morphology      Received:  18 June 1993      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1993/V29/I6/28 1 Sundararaman M.
