在研究和分析了多种快速冷凝制粉装置的工作原理后,提出了金属熔体的多级快速凝固过程的成粉理论,并以此理论为基础研制出一系列制取微细金属粉末的新型快速冷凝装置。这类装置能够生产多种非晶、准晶、微晶和微细金属粉末,制粉装置的冷凝速度为105~106k/s,粉末平均粒度最细可达5~l5μm,生产量为2~5kg/mjn,可连续生产,生产成本和普通气体雾化方法相当。对装置的工作特性进行了详细介绍,其结果表明,由著者发明的多级快速凝固装置既是制取非晶、准晶、和微晶粉末的理想装置,又是制取微细金属粉末的高效装置。

The synthesis of elevated-temperature intermetallic powders was carried out using a novel solid–liquid reaction milling technique. Asopposed to the conventional mechanical milling, the direct formation of nanometer-sized elevated-temperature intermetallic powders such as Fe1.3Sn and Fe3Sn2, at relatively low temperatures and an enhanced solid solubility extension of iron in lead were realized.

【期刊论文】Solid atomization technology and process of molten metal and alloy

A novel solid atomization technology has been developed with a high-velocity gas jet stream containing solid salt particles as the atomization medium. Metal and alloy powders with a finer particle size, a narrower size distribution and a higher cooling rate than those of the conventional gas atomization technology have been produced by this technology. The affecting factors of the particle size of as-prepared metallic powders have been analyzed, especially the influence of the state of NaCl particles.
