摘要

通过改变机械振动频率、振幅和振动角度

考察了不同机械振动参数对A356合金的组织与力学性能的影响。结果表明

当振动频率为20

0Hz、振幅为0.3

.6mm

机械振动角度为0°时

A356合金中的初生α-Al相和二次枝晶细小

A356合金可以取得理想的强度和塑性结合。

Abstract

The effects of different mechanical vibrating parameters

such as vibration frequency

amplitude and vibrating angle

on the mechanical properties and microstructure of A356 alloy were investigated by tensile testing and microstructural observation.The results show that primary Al phase and secondary dendrite in A356 alloy exhibit fine with desirable strength and elongation with frequency of 20

0Hz

amplitude of 0.3

.6mm as well as vibration angle of zero.
