摘要
在Zwick/Roell Z020万能材料试验机上实施高温压缩试验,研究铝合金6061在变形温度范围为360～480℃,应变速率在0.001～1s-1时的热变形行为。基于动态材料模型理论,利用matlab进行三次样条插值,获取足够的数据利用origin软件绘制铝合金6061的功率耗散图。利用功率耗散图分析确定了试验参数范围内热变形过程的最佳工艺参数。在加工温度为360～440℃,应变速率为0.001～0.01s-1之间,功率耗散率的最大值为0.39,是该合金的最佳成形区域。
The deformation behavior of 6061 aluminum alloy was investigated by hot-compression test on Zwick/Roell Z020 Universal test machine. The test was performed in the temperature range between 360 ℃ to 480 ℃ and strain rate between 0. 001 s 1 to 1 s^-1. By cubic spline interpolation in matlab, the processing map was calculated and analyzed according to dynamic materials mode（DMM）. The optimum processing parameters of hot deformation in the range of this experiment could also be obtained by the map. Temperature between 360℃ to 440℃ and strain rate between 0. 001 s-1 to 0.01 s-1 is the most suitable area for processing, and the power dissipation factor is up to 0.39 in this area.
