摘要

对体积分数为5%的SiC颗粒增强的A356复合材料和A356合金分别进行吸铸试验

测量熔体充型与凝固过程中铸件和铸型的温度

讨论了SiCp/A356复合材料与A356合金的铸件和铸型的温度变化规律。结果表明

SiCp的加入使SiCp/A356复合材料凝固前温度下降速度增大

凝固后的温度下降速度减小;同时由于潜热不同

SiCp/A356复合材料结晶温度低于A356合金。

Abstract

Suction casting SiCp/A356 metal matrix composites（MMCs）with 5% reinforced particles and A356 alloy were carried out

respectively.Temperature of castings and mould during filling and solidification process was measured to discuss the temperature variation of SiCp/A356 composites and A356 alloy castings and their moulds.The results show that SiCp addition can increase the temperature-decrement rate of SiCp/A356 composites before solidification and decrease the temperature-decrement rate after solidification.In addition

due to the difference of latent heat between the composites and the matrix alloy

the solidification transformation temperature of SiCp/A356 composites is lower than that of A356 alloy.
