摘　　要：研究了不同单一微量高熔点Mn、Ti、Nb元素对工业纯铝组织的影响,不同微量高熔点Mn、Ti、Nb元素及Al-Ti-B细化剂复合加入对工业纯铝组织的影响。研究表明:不同微量高熔点合金元素单一加入对工业纯铝组织细化效果明显;不同微量高熔点元素复合加入纯铝中要比单一加入对组织细化效果更好。The effects of different single trace elements with high melting point （Mn, Ti and Nb） on the microstructure of industrial pure aluminum were studied, and the effect of compound addition of the different trace elements and AI-Ti-B refiner on the microstructure of industrial pure aluminum was also studied. The results show that the refinement effect of different single trace elements with high melting point alloy on industrial pure aluminum is obvious, and the effect of compound addition on microstructure refinement of pure aluminum is better than that of only one single trace element.
