摘要
镁合金是一种具有发展潜力的轻合金材料 ,但尚有待进一步的研究 .通过实验研究静磁场作用下镁合金AZ6 1的凝固过程及其组织 ,发现在施加静磁场后镁合金的组织发生明显变化 ,晶界减薄 ,溶质元素含量在晶内显著增加 ,而在晶界处略有下降 ,因此静磁场改善了镁合金的组织 。
Magnesium alloy is a light alloy material with potential applications, but many problems need to be studied for it.In the experiment the process of solidification and the microstructure of magnesium alloy under the effect of magnetostatic field was studied.Some phenomena were found that the microstructures of magliesium alloy were changed obviously:the thickness of grain boundary was reduced,the content of solute in the grain was increased apparently and reduced slightly in the grain boundary.The analysis showed that urlder the effect of magnetostatic field the microstructure of magnesium alloy was improved,and this has great significance to improve the propenies of magnesium alloy.
