【摘要】 研究了6063合金中的微量Si、Mg元素对Al-Ti-C中间合金细化效果的影响,并探讨了其影响机理。结果表明:微量的Si、Mg元素均能促进Al-Ti-C中间合金对6063铝合金的细化作用,一般Si的含量在0.5%时,Al-Ti-C的细化效果最佳。在细化温度相同的情况下,Mg的促进作用更明显一些并且不存在"温度效应"。试验表明,当6063铝合金中同时存在微量的Si、Mg元素时,Al-Ti-C的细化效果会更加显著。更多还原

【Abstract】 The influence of small amount of elements magnesium and silicon in the 6063 alloy on the grain refining effect of Al-Ti-C master alloy was studied.The results show that the grain refining effect of Al-Ti-C master alloy can be promoted by them.The grain refining effect is best when the amount of silicon is 0.5%. At the same temperature,the refining effect of magnesium is appreciable and " temperature action is not found.The study indicates the grain refining effect of Al-Ti-C master alloy is remarkable when the elements magnesium and silicon exist in the 6063 alloy at the same time.更多还原
