中文摘要：

本项目系统研究了多相金属熔体微观反应与结构演变机制，从团簇演变角度研究了铝熔体中Al-P原子团簇的演变规律与AlP晶体生长机制，提出了初晶Si和Mg2Si相异质生核与生长新机制；揭示了铝熔体中TiCx结构演变的原子空位迁移机制，提出了B/N掺杂碳空位抑制TiCx结构演变与激励生核机制，并研制出B/N掺杂碳化钛型Al-Ti-C-B-N中间合金。基于多相金属熔体微观反应机制和难溶合金的合成原理，发明了具有重要应用价值的Si-P和Al-P系中间合金。Al-P系合金使Al-Si磷细化过程环境友好, 并实现磷定量加入；Si-P系合金解决了高硅铝和Mg-Si细化难题，为其应用开辟了广阔前景。Si-P和Al-P系合金已在全国十八个省获推广应用，并出口韩国、日本和东南亚各国。现已销售上述中间合金5000余吨，实现了规模化工业应用。该项研究的科学意义主要体现在Al-P和Si-P系合金为该合金系实验相图提供了重要素材；生核新机制的提出为传统金属材料改性提供了新思路；B/N掺杂抑制TiCx演变与激励生核机制为生核剂的研究提供了理论依据；提出的合金制备新技术为其它新材料研发开辟了新途径。
