摘要
以铝合金作为实验材料,开展了行波磁场与振荡磁场对铸锭组织及成分的作用规律研究。结果表明:行波磁场和振荡磁场均能有效的细化晶粒组织。行波磁场得到的晶粒组织多为等轴状的枝晶组织,晶粒平均尺寸为251.67μm。振荡磁场得到的晶粒组织则多为不规则的球形组织,晶粒平均尺寸为239.37μm。无磁场条件下的元素最大含量偏差为1.03,行波磁场下的元素最大含量偏差为0.56,而振荡磁场下的元素最大含量偏差为0.31。
In this paper,the effect of traveling magnetic field and oscillating magnetic field on the microstructure and composition of aluminum alloy ingot was studied.The results show that both traveling wave magnetic field and oscillating magnetic field can refine grain structure effectively.The average grain size of traveling wave magnetic field is 251.67μm.The grain structure obtained by oscillating magnetic field is irregular spherical structure,and the average grain size is 239.37μm.The maximum deviation of element content of traveling wave magnetic field is 0.56,and that of oscillating magnetic field is 0.31.However,without magnetic field,the maximum deviation of element content is 1.03.
