    摘要:

    采用传统铸造方法制备Mg-Zn-Y合金,基于典型的含二十面体准晶相的Mg93Zn6Y1合金,研究了铸态Mg-Zn-Y合金的枝晶形貌与其阻尼性能的关系。通过控制浇注温度,搅拌速度和搅拌时间,获得不同参数下的合金的枝晶形貌。结果表明,铸态Mg93Zn6Y1的显微组织主要由α-Mg树枝状晶体和二十面体准晶相组成。搅拌后,初始α-Mg树枝状晶体逐渐具有分形特征,且其尺寸变化,从而影响合金的阻尼能力。本文详细讨论了这一机制。

    Abstract:

    Conventional casting method was adopted to fabricate the alloys of Mg-Zn-Y, in which the dendritic morphology and its relation to the damping properties of as-cast Mg-Zn-Y alloy were studied based on the typical Mg93Zn6Y1 alloy containing icosahedral quasicrystal phase. By controlling the pouring temperature, the stirring speed and stirring time, the dendritic morphology with different parameters was obtained. The results show that the microstructure of the as-cast Mg93Zn6Y1 mainly consists of α-Mg dendritic crystal and icosahedral quasicrystal phase. After stirring, the primary α-Mg dendritic gradually have fractal characteristics in faith, and its size changes, affecting the damping capacity. The mechanism was discussed in detail.
