摘要

以8011合金为对象

研究了其精炼、除气、变质、铸轧、热处理后的组织变化及力学性能。结果表明

铝液中杂质在二次精炼后几乎完全消失;变质后晶粒更加均匀;冷轧后板带出现加工硬化

伸长率降低;再结晶热处理后

晶粒得到细化

加工硬化得以消除。

Abstract

Effects of refining process

degassing

modification

roll-casting and heat treatment on microstructure and tensile properties of 8011 alloy were analyzed.It is found that after secondary refinery

the impurities are almost removed.Grains are refined with more homogenization after modification.Cold rolling strips are strengthened with decrease of elongation.Recrystallization treatment can improve the grain size and eliminate the working hardening effects.
