| 中文摘要 | Friction stir processing was used to produce ultrafine-grained Al-Zn-Mg-Cu alloy. Low-temperature superplasticity of 350-540% was achieved at 200-350 degrees C. Increasing the temperature resulted in an increased optimum strain rate for maximum elongation. At 350 degrees C, the optimum strain rate shifted to a high strain rate of 1 x 10(-2) s(-1). A strain rate sensitivity of 0.33-0.42 was observed for maximum elongation at the investigated temperatures. Grain boundary sliding was observed even at 200 degrees C. (C) 2007 Acta Materialia Inc.
