等温热处理对az61稀土镁合金半固态组织的影响
Keywords: 金属材料,az61稀土镁合金,等温热处理,半固态,显微组织
Abstract:
？研究了等温热处理对az61稀土镁合金半固态组织的影响,结果表明:随着等温热处理温度的升高,铸态合金中的初始枝晶组织演变成了半固态非枝晶组织,经过了粗化、组织分离和球化三个过程。在等温热处理过程中,稀土la的加入阻碍了原子向固相粒子的聚集和固相粒子的合并,抑制了固相粒子的进一步长大,使半固态非枝晶组织更加细小。经过不同保温时间后,不规则的大块状组织开始球化,形成大量的近球形颗粒。但是,随着保温时间的进一步延长,球化的颗粒开始粗化长大且在颗粒内形成了大量的液岛。枝晶组织的球化过程,包括二次枝晶壁消失和ostwald熟化。
