It seems obviously due to: (1) coarsening of mean size of principal precipitate M_(23)C_(6), (2) precipitation of Laves phase MoFe_2, (3) decrease of solution Mo content in matrix and (4) recovery and recrystallization occurred. Key words:  20Cr11MoVNbNB Steel      Laves phase MoFe_2      aging      strength      hardness      Received:  18 June 1991      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/Y1991/V27/I6/33 1 Larson F R, Miller J.
