Abstract：The temperature dependence of fracture toughness of materials seems to haveanalogy to that of yield strength.This similarity for low-carbon steel has beenapproached on the basis of the plastic work loss at the crack tip.Both obey theexponential law and are in agreement with experiment.The availability to enquirefor the temperature dependence of fracture toughness for certain materials otherthan low-carbon steel from that of yield strength has been also discussed. 收稿日期: 1985-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 龙期威 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I1/69 1 Hahn,G.T.;Hoagland,R.G.;Rosenfield,A.R.,Metall.Trans.,2(1971) ,537． 2 龙期威;何青;周敬,物理学报,21(1965) ,1264． 3 Zwiesele,S.;Diehl,J.,Strength of Metals and Alloys,Proc.of the 5th Int.Conf.Aachen,Federal Republic of Germany,Aug.1979,Eds.Haasen,P.;Gerold,V.;Kostorz,G.,Vol.3,Pergamon Press,1980,p.59． 4 周敬;何青;邹本三;龙期威,科学通报,17(1966) ,497． 5 Petch,N.J.,Philos.Mag.,3(1958) ,1089． 6 #12 7 中村素;内木虎藏;冈林久喜,日本金属学会志,36(1972) ,82． 8 龙期威;高桦,金属学报,19(1983) ,A225． 9 何青;熊良钺;龙期威,科学通报,17(1966) ,500． 10 Hutchison,M.M.,Philos.Mag.,8(1963) ,121． 11 中国科学院金属研究所,东北电力局技术改进局金属室,阜新发电厂金属室,机械工程学报,17(1981) ,62 No related articles found!
