摘　　要：根据3003铝合金热压缩试验数据,采用动态材料模型构建了铝合金的热加工图,研究了铝合金的微观组织演变并建立了热变形机制图。结果表明,3003铝合金在低温高速区域发生加工失稳;在中温高速区域,发生动态再结晶,并且此区域为热加工的最佳区域。The thermal processing map of the aluminum alloy 3003 was established by the dynamic material model according to the experimental data of the thermal Compression, and the microstrueture evolution of the aluminum alloy was investigated and the thermal deformation mechanism map was established. The results show that the processing instability occurs in low-temperature high-speed region. While the dynamic recrystallization appears in middle-temperature high-speed region, which is optimal region for the thermal processing.
