| 英文摘要 | Friction stir processing (FSP) was applied to extruded Al-4Mg-1Zr to produce fine-grained microstructure with grains sized 0.7-1.6 μ m. Low temperature deformation behavior was investigated at 175° C and initial strain rates of 5 x 10(-5)-3 x 10(-3) s(-1). Low temperature superplasticity was observed in ultrafine-grained material. A maximum superplastic elongation of 240 % was obtained in ultrafine-grained (0.7 μ m) ESP sample at an initial strain rate of 1 X 10(-4) s(-1) where a maximum strain rate sensitivity of 0.34 was observed. © 2005 Acta Materialia Inc.
