摘要

研究了不同的脉冲电压、频率及模具预热温度对SiCP/AZ91D复合材料凝固组织的影响。结果表明

通过控制脉冲磁场参数和模具预热温度

可以有效改变SiC颗粒在合金凝固组织中的分布;在0

00V范围内

随着脉冲电压的增加

SiC颗粒逐渐分散均匀

但是当电压升高到250V时

SiC颗粒有团聚的趋势;在0

Hz范围内

随着脉冲频率的增加

SiC颗粒分布逐渐均匀;在室温到600℃范围内

在磁场处理条件下

随着模具温度的升高

SiC颗粒分布逐渐均匀。

Abstract

Effects of different pulse voltage

frequency and mold preheating temperature on solidification microstructure of SiCP/AZ91 Dcomposites were investigated.The results show that the distribution of SiC particle in solidification structures of alloy can be improved effectively by controlling parameters of pulsed magnetic field and mold temperature.With the increase of pulse voltage in the range of 0

00V

SiC particles are uniformly distributed increasingly

however

the voltage reaches 250 V

SiC particles exhibits agglomeration tendency.With the increase of pulse frequency in the range of 0

SiC particles is uniformly distributes gradually.With the increase of mold temperature in the range of room temperature

00 ℃

SiC particles are evenly distributed gradually under the conditions of magnetic field treatment.
