摘要

在2024铝合金的凝固过程中施加低压脉冲磁场处理

研究了低压脉冲磁场作用下2024铝合金凝固组织的变化

考察了浇注温度和放电电压对2024铝合金凝固组织中α-Al相形貌和尺寸的影响。结果表明

在低压脉冲磁场的作用下

2024铝合金凝固组织中的初生α-Al相和共晶组织均显著细化。浇注温度越接近液相线温度

初生α-Al的平均晶粒尺寸越小。随着放电电压的升高

初生α-Al的平均晶粒尺寸逐渐减小

当放电电压为250V时

平均晶粒尺寸达到最小值。

Abstract

Effects of the low voltage pulsed magnetic field（LVPMF）on solidification structure of 2024 wrought aluminum alloy were investigated

and the effects of pouring temperature and discharging voltage on morphology and size of α-Al phase in 2024 wrought aluminum alloy were observed.The results show that primary and eutectic phase in the alloy can be refined obviously by LVPMF.With the pouring temperature near to liquidus temperature increasingly

the average grain size is refined gradually.With the increase of discharging voltage

average grain size of primary α-Al particles is decreased.With discharging voltage of 250V

average grain size of primary α-Al particles reaches minimum values.
