摘要
通过试验的方法在不同变形程度等条件下对 2A50合金进行性能测试和金相分析 ,结果表明经过挤压变形后 ,2A50合金晶粒被细化 ,纵向组织被拉长 ,铸造缺陷改善 。
The microstructure and mechanical properties of 2A50 al loy under different extrusion ratios were investigated. The results showed that the grain of the alloy was refined, microstructure in longitudinal direction was elongated, the casting defects were eliminated and the mechanical properties we re ascended with increase in extrusion ratio.
