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。
The finite element DEFORM-3D software was used to simulate the extrusion of aluminum alloy 1100 at normal temperature and semi-solid state to explore the high temperature forming properties of 1100 alloy. The results show that the maximum flow velocity reaches 49mm / s at 500 ℃ and only 12.7mm / s at 20 ℃. The maximum equivalent strain field reaches 3.63 at 500 ℃ and only 5.01 at 500 ℃ When the maximum value of the equivalent stress field reached 12.3MPa, while only 42.9MPa at 20 ℃. In summary, the semi-solid aluminum 1100 when the forming performance is much better than normal temperature.
