摘要

验证了铝合金中微量Zr及Mn对Al-Ti-B中间合金细化效果的影响。发现Mn对Al-Ti-B中间合金的细化效果无中毒作用

而Zr在一定浓度范围内显著降低其细化效果;而且提高熔炼温度会加剧Zr对Al-Ti-B中间合金的中毒作用。研究还发现

微量Al-Ti-B及Al-Ti中间合金也会使Zr对铝的细化效果产生中毒作用。

Abstract

The effects of minor Zr and Mn in aluminum alloy on grain refinement of pure aluminum with Al-Ti-B master alloy have been validated. The results reveal that Mn can not affect the refining efficiency

however

the Zr can result in seriously poisoning the Al-Ti-B master alloy. Furthermore

the poisoning effects of Zr become more serious with increasing the molten temperature. In addition

minor Al-Ti-B and Al-Ti master alloy can affect the refinement efficiency of Zr on the pure aluminum. The poisoning mechanism of Zr element has been approached also.
