长周期堆垛相对Mg-Zn-Y合金的阻尼性能影响
Effect of long period stacking ordered phase on damping capacities of as-cast Mg-Zn-Y alloys
摘要
Abstract
The mierostructure and damping capacities of MgZnx Y1.33x (x=1-4 at.％) alloys were discussed and researched.The main phase composition of the alloys consists of a-Mg and long-period stacking ordered (LPSO) phase.Due to increased LPSO phase,grain size was refined.LPSO phase was advantageous to the damping properties of the Mg-Zn-Y alloys.Mg-7％ Zn-12.8％Y has the highest damping capacity up to 0.04.Due to stacking fault probability,the LPSO phase in the Mg-Zn-Y alloys could be new damping source to dissipate energy so as to contribute to the improvement of damping capacities.关键词
