摘要

　采用楔形试样等温压缩

结合计算机模拟和现代冶金分析技术

研究了变形参数(变形温度、变形程度)对LD10铝合金微观组织及力学性能影响的规律.结果表明:在同一温度下

随着变形程度的增加

晶粒呈现细化的趋势

试样硬度逐渐增大;在(350～410)℃

形变强化起主导地位

硬度随温度的升高呈现下降的趋势;而在(410～470)℃范围内

逐渐出现固溶现象且有时效析出

试样硬度随温度升高逐渐增大.依据实验结果

可对LD10塑性加工时的微观组织及性能进行预测及控制

同时为实现铝合金组织控制变形提供了依据.

Abstract

Adopted isothermal compression of wedge specimen and combined numerical simulation with modern metallurgy technology

the effect of deformation parameters on microstructure and mechanical property of LD10 was studied. The result manifested that crystal grain becomes fine because of dynamic recrystallization and hardness increases as degree of deformation increases at the same temperature. At (350～410) ℃

hardness decreases gradually as deformation temperature increases by virtue of work hardening; however

at (410～470) ℃

hardness increases gradually as deformation temperature increases resulting from solution strengthening and age-hardening. It can provide theoretical basis for achievement structure control deformation of aluminium alloy.
