With increasing aging time,Ni3Mo and Ni3Ti particles coalesce significantly and may be partly resolved into the matrix, and simultaneously the Fe2Mo particles precipitate and the reversed austenite can be found.Correspondent:YIN Zhongda,pro fessor,Campus Post Box 433,Harbin institute of Technology, Harbin 150001 Key words:  18Ni maraging steel      aging process      spinodal decomposition      intermetallics.reversed austenite      Received:  18 January 1995      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/Y1995/V31/I1/7 1铃木朝夫．铁钢,1973;59:8222VasudevanVK,KimSJ,WaymanCM．MetallTrans,1990;21A:26553江伯鸿,WagnerR．金属学报,1986;22:A5004张美华,江伯鸿、徐祖耀．材料科学进展,1991;5:1065ShaW,CerezoA、SmithGDW,SurfSci,1991:246:2786MurakamiM,KawanoO,MurakamiY,MorinagaM．ActaMetall,1969,17:15177RackHJ,KalishD．MetallTrans,1971;2:30118SpoonerS,RackHJ,KalishD．MelallTrans,1971;2:23069MarcusHL,FineME,SchwartzLN．J Applphys,1967;38:475010朱静,李荣,张丽萍．金属学报,1986;22:A304 [1] XIANG Zhaolong, ZHANG Lin, XIN Yan, AN Bailing, NIU Rongmei, LU Jun, MARDANI Masoud, HAN Ke, WANG Engang.
