摘要

利用商业软件Flow-3D

模拟了A356合金半固态触变压铸和普通压铸的充型流动过程。模拟结果表明:相同模具结构中的半固态压铸和普通压铸充型过程

半固态流动平稳

普通压铸由于湍流流动

因而容易出现气孔、卷气夹杂等缺陷。半固态触变压铸和普通压铸具有相同的流动通道。

Abstract

Filling process of A356 alloy in semi-solid thixo-forming die casting and in conventional die casting has been simulated based on a Flow-3D system. Simulated results indicate that filling process in semi-solid thixo-forming die casting is smooth

while it is turbulent so gas-hole

gas-entrapped etc.

were easily generated in conventional die casting through with the two kinds of die casting in the same mould structures. However

there exists the same flow channel in both semi-solid thixo-forming die casting and conventional die casting.
