摘　　要：采用有限元DEFORM-3D软件对铝合金1100进行常温态和半固态下的挤压模拟,以探索1100合金材料的高温成型性能。结果显示,500℃时流动速度的最大值达到了49mm/s,而20℃时只有12.7mm/s;500℃时等效应变场的最大值达到了3.63,而20℃时只有5.01;500℃时等效应力场的最大值达到了12.3MPa,而20℃时只有42.9MPa。综上所述,半固态时铝合金1100的成型性能要比常温态好得多。Using finite element software DEFORM-3D,the extrusion forming of 1100 aluminum alloy was simulated in semi-solid state and room temperature to explore the high temperature forming performance of 1100 aluminum alloy.The results show that the maximum flow rate reaches 49 mm/s at 500 ℃,and only 12.7 mm/s at 20 ℃;the maximum equivalent strain reaches 3.63 at 500 ℃,and only 5.01 at 20 ℃;the maximum equivalent stress reaches 12.3 MPa at 500 ℃,and only 42.9 MPa at 20 ℃.The forming performance of 1100 aluminum alloy is much better in semi-solid state than in the normal temperature state.
