By measuring the length of the cracks near impression the toughness and the fracture strength were evaluated to be about 1.0 MPa·and 450 MPa,respectively.No obvious change of microhardness or toughness was found after 850℃, 36 h annealing.But the fracture strength rised to 550 MPa.MENG Xiangmin,(Institute of Metal Research,The Chinese Academy of Sciences,Shenyang 110015) Key words:  Quasicrystal      mechanical property      AlCuCo alloy      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/I2/61 1ShinkaiN,BradtRC,RindoneGE．JAmCeramSoc,1982;65:1232SainfortP,DubostB．In:JanotC,DuboisJMeds．,QuasicrystallineMaterials,Singapore:WorldScienctific,1988:3613TakeuchiS,IwanagaH,ShibuyaT．JpnJApplPhys,1991;30:5614SongSengkang,DuboisJM．PhilosMag,1991;66A:1515HeLX．WuYK,KuoKH．JMaterSciLett,1988;7:12846LinSY,WangXM．LuL,ZhangDL,HeLX,KuoKH．PhysRev,1990;B41:96257JinZZ,MaJR,LuZW．ProcIntSymponAPCS,1986 [1] ZHANG Leilei, CHEN Jingyang, TANG Xin, XIAO Chengbo, ZHANG Mingjun, YANG Qing.
