Metastable x-phase, characterized by (1/2) <001> and (1/8) <210> superlattice diffraction spots,was newly discovered. It is confirmed by the combination of SAD and reduced cell program analyses that x-phase belongs to monoclinic crystal system. Its lattice parameters were determined to be:a=0.669 nm, b= 0.603 nm, c= 0.951 nm and β=95°.Correspondent:ZHAO Hingzhong, lecturer, Faculty of Metallic Materials, Department of Materials Science and Engineering, Huazhong University of Science and Technology, Wuhan 430074 Key words:  TiNi      shape memory alloy      superlattice diffraction spot      metastable x-phase      Received:  18 July 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/I7/302 1GooE,SinclairR,ActaMetall,1985;33:17172MichalGM,MoineP,SinclairR．ActaMetall．1982;30:1253WuSK,WaymanCM．ActaMetall,1988;36:10054ZhaoXZ,WuXF,KoT．ActaMetall,1989;37:17835GooE,DuerigT,MeltonKN,SinclairR．ActaMetall．1985;33:17256TadakiT,NakataY,ShimizuK,OtsukaK．TransJpnInstMet,1986;27:731 [1] YANG Chao, LU Haizhou, MA Hongwei, CAI Weisi.
