利用强迫振动扭摆方法对Zn Al二元合金熔化过程的低频内耗进行了研究 .结果表明 ,Zn Al二元合金熔化过程的内耗峰与其固态相变内耗峰的特征有较大差异 .结合该合金熔化过程的微观结构变化 ,初步分析了内耗峰的形成机理 .
The results show that the internal friction peak of Zn Al binary alloy melts with the characteristic of the internal friction peak of the solid phase transformation is quite different. Combined with the melting of the alloy Process microstructure changes, preliminary analysis of the internal friction peak formation mechanism.
