The results show that the microtwinning plane is(111) and microtwin results from the movement of (1/6)[112] Shockley partials. The microtwinning can moved across the twin-related interface of lamellar TiAl phase without changing the twinsystem. These results indicate that the twin-related interface of TiAl can not hinder the microtwinning effectively. The effects of microtwinning on the deformation of PST crystal have been discussed. Key words:  PST crystal      TiAl      intermetallic      twin.      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/I9/393 1KimYW,JOM,1989;41:242TsujimotoT,HashimotoK．In:LiuCT,TaubAI,StoloffNS,KochCC,eds．HighTemperatureOrderedIntermetallicAlloysⅢ,MRSSympProc,Pittsburgh,PA:MRSSociety,1989;133:3913HuangSC,HallEJ．ActaMetallMater,1991;39:10534ZhaoLR,TangriK．PhitosMagA,1992;65:10655MorrisMA．PhilosMagA,1993;68:2376FujiwarwT,NakamuraA,HosomiM,nishitauiSR,ShiraiY,YamaguchiM．PhilosMagA,1990;60:5917YamaguchiM,UmakoshiY,ProgrinMaterSci．1990;34:658TunstallWJ,GoodhewPJ．PhitosMag．1966;13:12599ShechtmanD,BlackburnMJ,LipsittHA．MetallTrans．1974;5:137310LipsittHA,ShechtmanD,SchafrikRE．MetallTrans,1975;6:199111HugG,LoiseauA,LasalmonieA．PhijosMagA,1986;54:47 [1] LI Fulin, FU Rui, BAI Yunrui, MENG Lingchao, TAN Haibing, ZHONG Yan, TIAN Wei, DU Jinhui, TIAN Zhiling.
