摘　　要：对比研究了硼对电解低钛铝合金组织细化效果衰退行为的影响。结果表明,通过熔配加入微量硼可显著提高电解加钛的晶粒细化能力,并可有效抑制电解低钛铝合金微观晶粒的粗化,提高了电解加钛晶粒细化的抗衰退能力。The fading behaviors of the structure refinement effect of electrolytic low-titanium aluminum alloys containing boron were investigated. The results show that addition of trace boron can improve greatly the grain refinement ability of titanium added by electrolysis and resist the grains of electrolytic low-titanium aluminum alloys becoming larger. So, the resisting fading ability of titanium added by electrolysis is increased.
