| 摘 要： | 国内外学者对掺杂元素对Al-Si共晶合金的影响进行了大量的研究,这些研究大都侧重于研究变质后的结果,如变质后的晶体结构形态以及掺杂元素对结构形态的影响,再根据变质结果反过来推测可能的变质机理,但对掺杂元素对Al-Si合金凝固过程本身的影响的研究却很少.本文拟采用差热分析法(DTA)和步冷曲线热分析法研究Na、Sr元素对Al-Si共晶合金凝固过程的影响,以探讨Al-Si共晶合金的成核机理。

| Abstract: | The influence of added elements on the solidification process of Al-Si alloys was systematially investigated by DTA and thermal analysis. It was obtained that Na.Sr in the melt can raise the temperature of eutectic solidification. Our work indicatesthat the traditional retard nucleation theory of modification may have someshortcomings. |
