为了研究非平衡凝固条件下(Fe83Ga17)100-xMx(x=0、0.5、1、1.5;M=C、B)合金的相组成及其磁致伸缩性能,采用吹铸的方式制备了(Fe83Ga17)100-xMx,(x=0、0.5、1、1.5;M=C、B)合金,结果表明,合金保持了A2(bcc-Fe(Ga))相结构.C、B元素对合金微观组织产生了很大影响,C完全固溶于bcc-Fe中,B于晶界处大量富集,晶粒形状呈区域定向排列.添加C、B均对Fe83Ga17合金的磁致伸缩性能产生了抑制作用.添加C增大了弹性模量,当x=1时磁致伸缩值最大;添加B对合金组织产生了巨大影响,随着B含量的增加形成了明显的铸造织构,并且生成了富含Fe2B的相,x=1.5时磁致伸缩值最大.
