为了研究工业纯铝的可加工性，并建立最优的热加工工艺参数，通过 Gleeble?1500热模拟压缩机，研究在温度为523~823 K，应变速率为0.005~10 s?1范围内纯铝的热变形行为。同时研究应变、应变速率和温度等加工参数对纯铝流动应力的影响。优化了由材料参数构成的九个分析因素和其相应的权重系数。建立了多级串联、多级并联和多级串并联规则的本构方程，其相关性系数 R 分别是0.992、0.988和0.990，平均绝对相对误差分别是6.77%、8.70%和7.63%，这证明串联本构方程能很好地预测纯铝的流动应力。
In order to study the work-ability and establish the optimum hot formation processing parameters for industrial 1060 pure aluminum, the compressive deformation behavior of pure aluminum was investigated at temperatures of 523?823 K and strain rates of 0.005?10 s?1 on a Gleeble?1500 thermo-simulation machine. The influence rule of processing parameters (strain, strain rate and temperature) on flow stress of pure aluminum was investigated. Nine analysis factors consisting of material parameters and according weights were optimized. Then, the constitutive equations of multilevel series rules, multilevel parallel rules and multilevel series ¶llel rules were established. The correlation coefficients (R) are 0.992, 0.988 and 0.990, respectively, and the average absolute relative errors (AAREs) are 6.77%, 8.70% and 7.63%, respectively, which proves that the constitutive equations of multilevel series rules can predict the flow stress of pure aluminum with good correlation and precision.
