摘要:

通过6013铝合金的热压缩模拟实验，研究了其在530~575℃、应变速率为0.001~0.1 s^-1条件下的热变形行为。基于电子背散射衍射技术分析了这种合金微观组织的演变及其动态软化机制，并用Zener-Hollomon (Z)参数表征变形温度和应变速率的综合影响。结果表明，这种合金的流变应力随着lnZ的增大而增大，在稳态条件下其变形激活能为217.3 kJ/mol。随着lnZ的增大，这种合金的再结晶面积分数和亚晶粒尺寸总体上呈线性降低的趋势。在23.91 ≤ lnZ < 29.55条件下动态再结晶是其主要的软化机制，其中几何动态再结晶占主导；而在29.55 < lnZ ≤ 30.24条件下，动态回复是其主要的软化机制。

Abstract：

The hot deformation behavior of 6013 Al-alloy at 530~575^oC and strain rate of 0.001~0.1 s^-1 was studied by hot compression simulation test. Based on the electron backscatter diffraction technique, the microstructure evolution and dynamic softening mechanism were discussed, while the so called Zener-Hollomon (Z) parameter was adopted to represent the combined effect of deformation temperature and strain rate. The results show that the flow stress of the alloy increases with the increase of ln Z, and the deformation activation energy of the alloy under steady state condition is 217.3 kJ/mol. With the increase of lnZ, the recrystallization area fraction and sub-grain size tend to decrease linearly. For 23.91 ≤ lnZ < 29.55, dynamic recrystallization is the main softening mechanism, in which geometric dynamic recrystallization is dominant. For 29.55 < lnZ ≤ 30.24, dynamic recovery is the main softening mechanism.
