摘要

研究了强脉冲磁场对LY12铝合金凝固组织及微观结构的影响。试验表明 :在强脉冲磁场作用下

LY12铝合金的凝固组织发生了显著变化

脉冲磁场处理使晶粒明显得到细化。另外

在磁场中凝固的试样与未经磁场处理的试样相比

X -射线衍射谱中的（111）、（2 0 0 ）、（3 11）以及（2 2 2 ）晶面的衍射峰得到显著增强

Abstract

The effects of strong pulsed magnetic field on the solidification microstructures of LY12 aluminum alloy were studied. It is showed that the solidification structures of LY12 aluminum alloy were changed remarkably and the strong pulsed magnetic treated grains in LY12 aluminum alloy were refined obviously. Otherwise

compared to un treated sample

the diffraction peaks of （111）

（200）

（311） and （222） crystal face in the X ray diffraction spectrum of magnetic treated sample were strengthened obviously.
