This alloy showed superplasticity in the temperature range of 750℃ to 900℃ under a strain rate of 1 × 10~(-3)/ s and maintained superplastic it at 850℃ in a relatively wide range of strain rate. The highest m value may exceed 500%. At 850℃ . m value changes from 0.22 to 0.41 under different strain rates. Optical and TEM observations revealed that a dynamic recrystallization process took place with the deformation process and this in turn resulted in the superplasticity in this alloy with large grains Correspondent: LIN Dongliang,professor , Department of Materials Science, Shanghai Jiaotong University,Shanghai 200030 Key words:  Fe_3Al      intermetallics      large grains      superplasticity      Service E-mail this article Add to citation manager E-mail Alert RSS Collect articles（） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I13/35 1McKameyCG,DeVanJH,TortorelliPF,SikkaVK．JMaterRes,1991;16:17792LiuCT,LeeEH,McKameyCG．ScrMetall,1989;23:8753LiuCT,McKameyCG,LeeEH,ScrMetallMater,1990;24:3854SikkaVK．ProceedingofStructuralIntermetallicsTMSSymposium．19935StoloffNS．ActaMetall,1964:12:4736MendirattaMG,LipsittHA．MetallTrans,1987;18A:2837DiehmRS,MikkolaD．E,In:LiuCTetal．eds．HighTemperatureOrderedIntermetallicAlloys,Vol．8l,Pittsburgh:MaterialsResearchSociety,1987;3298NiehTG,MayoMJ,KobayashM,WadsworthJ．Superplasiicity,inMetals,CeramicandIntermetallics,Pittsburgh:MaterialsResearchSociety．196:1899OchiaiS,KobayashM,MichimnraK,MayoMJ,KobayashM,WadsworthJ．SuperplasticityinMetals,CeramicandIntermetallics,Pittsburgh,MaterialsResearchSociety,196:20110BackofenWA,TurnerIR．AveryDH．TransASM,1964;57:98011GriffithP,HammondC．ActaMetall,1972;20:93512GhoshAK．AyresRA,MetallTrans,1976;7A:1589d [1] WANG Huiyuan, XIA Nan, BU Ruyu, WANG Cheng, ZHA Min, YANG Zhizheng.
