摘要

通过高能超声稀释原位反应烧结块

制备锌铝合金基复合材料。试验表明

复合材料组织分布均匀

强度较基体有大幅度提高

增强机制为Orowan强化理论。高能超声均匀稀释增强相是声空化与声流效应协同作用的结果。

Abstract

The Zn-Al alloy matrix composites were prepared by high-intensity ultrasonic dilution of XD denoted in situ composites. The experiment showed that the tensile strength of the composites with particles of homogeneous distribution in the matrix was much higher than that of the matrix. The strengthening mechanism was attributed to Orowan theory. The evenly diluted strengthening phase of XD composites by high-intensity ultrasonic resulted from the cavitation in association with acoustic stream.
