摘要

采用旋转浇注法制备AZ91D合金半固态浆料

获得了符合金属半固态加工要求的细小、近球状的非枝晶组织。研究表明

适当降低浇注温度、提高旋转管转动速度或采用合适的倾角

半固态组织的初生相颗粒会变得细小、均匀和圆整。在本试验条件下得到的优化工艺参数:浇注温度为630℃

旋转管转速为75r/min

旋转管倾角为25°。

Abstract

The semi-solid slurry with fine near-spheroidal structure of AZ91D alloy was prepared bya rotary pouring method.The results reveal that the primary phase particles with distributed fine spheroidal in semi-solid structure can be presented with decreasing the pouring temperature and increasing rotating velocity of the duct as well as choosing proper declined angular.The desirable semi-solid microstructure can be obtained with pouring at 630 ℃ and rotating at 75 r/min as well as declined angle of 25°.
