摘要 在Gleeble-1500热/力模拟机上对2026合金进行了热压缩试验,研究了其在温度300~450℃和应变速率0.01~10 s-1条件下的热变形行为。结果表明:热变形过程中的流变应力可以很好用双曲正弦本构关系来描述,通过优化α值,可以更精确地得到该合金的表观激活能为230.51kJ/mol。根据材料动态模型,计算并分析了2026合金的加工图。利用加工图确定了热变形的流变失稳区,合金在热加工温度450℃,应变速率为0.01 s-1时可加工性最优。 Gleeble-1500 thermal/mechanical simulator 2026 alloy on the hot compression tests were studied in the temperature 300~450 ℃ and strain rate of 0.01~10 s-1 under the conditions of hot deformation behavior.The results show that:during the hot deformation,the flow stress can be well described by the hyperbolic sine constitutive,by optimizing the value of α,it can be obtained more accurately the apparent activation energy of the alloy which is 230.51 kJ/mol.According to the dynamic materials model,it calculated and analyzed the processing of alloy 2026 figure with the use of hot deformation processing maps,it identified areas of flow instability,and the alloy in the thermal processing temperature 450 ℃,strain rate of 0.01 s-1 had the optimal processing ability.
