摘要：
PM 2024Al-3Fe-5Ni alloy has been fabricated by an air atomization technique followed by extrusion at 623 K and warm rolling at 523 K. After the warm rolling, this alloy exhibited ultrafine grained structure. Strain rate sensitivity indexes, m, larger than 0.3 and superplastic elongations higher than 250% were observed in the fine grained alloy at the strain rates higher than 2x10(-1) s(-1) and at the temperature of about 773 K, which is very close to the solidus temperature of this matrix alloy.
