摘要

将行波磁场作用于ZL205A合金凝固过程中

研究了不同励磁电流强度的行波磁场对ZL205A合金试样中Cu元素分布、凝固组织以及晶粒尺寸的影响。结果表明

对ZL205A合金凝固过程中施加行波磁场

合金中Cu元素分布更均匀

细化相颗粒形成的明显沉积层厚度减小

且随着励磁电流强度的增加沉积层厚度逐渐减小

直至消失。经分析

这是由于行波磁场促进细化相颗粒向试样其他位置移动

避免其在底部沉积

同时提高了试样上部的形核率

减小了试样上部的晶粒尺寸。

Abstract

Raveling magnetic field（TMF）was applied in the solidification of ZL205 Aalloy.The effects of different TMF current intensity on element distribution

microstructure and grain size of ZL205 Aalloy samples were investigated.The results show that distribution of Cu element is more uniform in the solidification of ZL205 Aalloy with TMF

and the grain size at the upper of the samples is refined.Due to the density difference

the deposited layer can be formed in the samples and thickness of the deposited layer is decreased with the increase of the intensity of excitation current and eventually disappear

which are attributed to the melt flow caused by TMF promoting the uniform distribution of solid phase and liquid phase.The element in the samples is more uniformly distribution and the deposition of the elements and phases can be avoided by TMF.
