The crack growth rate in weld metal and HAZ of steel 36Z fatigued at low frequency may be 3-5 and 4-10 times that at high frequency respectively. The crack growth rate for steel 36Z may fairly match that of A537. The crack growth model and fracture feature of weld metal in corrosive medium were also discussed. Key words:  weld metal      corrosion fatigue      crack growth      Received:  18 May 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/I5/95 1 Gerbrich W W, Katz Y.
