摘要
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 low-frequency internal friction in Zn-Al binary alloy during the melting process is measured via forced vibration torsional pendulum. It is shown that the internal friction accompanied with the melting process of the alloy is far from that accompanied with the eutectoid transition in this alloy. According to the structure variation during the melting process, the mechanism to form the internal friction peak is discussed.
