The results show that the resistance of the alloy with rapidly as－cast structure to erosion－corrosion is superior to aged one, although its hardness may be raised by aging treatment. The main reason why the rapid solidification of the alloy improves the erosion－corrosion resistance was also been discussed.WEI Xiangyun, associate professor,(Institute of Corrosion and Protection of Metals, The Chinese Academy of Sciences, Shenyang 110015 Key words:  cast alloy      Cr30Nil7Mo2Cu      solidification      microstructure      element distribution      erosion-corrosion      Received:  18 February 1994      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/Y1994/V30/I2/91 1郑玉贵,姚治铭,龙康,李生春,柯伟．腐蚀科学与防护技术,1993;5:2862PittCH,ChangYM．Corrosion,1986;42:3123MadsenBW．Wear,1988;123:1274YueZ,ZhouP,ShiJ．In:LudemaKCed．,WearofMaterials1987,ProcIntConfonWearofMaterials,NewYork:ASME,1987:635姜晓霞,李诗卓．化工机械,1991,18:150 [1] ZHANG Leilei, CHEN Jingyang, TANG Xin, XIAO Chengbo, ZHANG Mingjun, YANG Qing.
