The results show that by addition of Cr and Ni, c/a ratio in Fe-Mn-Si alloy has been increased from 1.620 to 1.656 and this is favourable to the formation of fec deformation twin. The penetration process of ε martensites on different {111}plane can be avoided through the formation of ε martensite in fcc twin, which is responsible for the better shape memory effect in Fe-Mn-Si-Cr-Ni alloy. Key words:  shape memory alloy      ε martensite      deformation twin      stress concentration      Received:  18 September 1995      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/Y1995/V31/I9/399 1OtsukaH,YamadaH,MuruyamaT,TanahashiH,MatsudaS,MurakamiM,ISIJInternational,1990;30:6742OtsukaHYamadaH,HanashiT,MaruyamaT．MaterSciForum,1990;56-58:6553GuQ,VanHumbeeckJ,DelaeyL．ScriptaMetetMat,1994;30:15874YangJH,WaymanCM．MetallTrans,1992;23A:14455YinFX,ZhangJX,GuMJ,ShimizuK．JMaterSciTechnol,1994:10:2636SatoA,ChishimaE,YamajiY,MoriT,ActaMetall,1984;32:5397WangXX,ZhaoLC,ScriptaMetetMat,1992,26:3038FederzoniL,GueninG,ScriptaMetetMat,1994;31:259RongLJ,LiYY,ShiCX．ScriptaMetetMat,tobepublished10SatoA,YamajiY,MoriT．ActaMetall1986;34:28711OtsukaH,KajiwaraS．MeiallTrans,1994;25A:63 [1] YANG Chao, LU Haizhou, MA Hongwei, CAI Weisi.
