摘要: 

深过冷液态金属(合金)凝固时伴随有显著的温度再辉,初生固相因此不可避免地部分被重熔,从而影响到最终凝固组织形态。近年来,过冷熔体中晶体生长理论模型不断完善,使得定量分析初生固相重熔程度随过冷度的变化规律成为可能,本文即对这方面的研究工作进展进行综述,并结合某些合金在不同过冷度下晶体生长行为及其凝固组织的实验结果,对典型非平衡凝固组织的形成机制进行阐述。

Abstract

Solidification of deeply undercooled alloy melts proceeds with obvious temperature recalescence, during which part of primary solid is inevitably remelted, and the microstructural morphology is inevitably changed. During past decades, great improvement was achieved in modelling crystal growth in undercooled alloy melts, making it possible to quantitatively evaluate the remelting degree of primary solid at different undercoolings. In this paper, the progress in modelling the remelting of primary solid was introduced, and the variation of remelted fraction of primary solid as a function of the alloy feature and undercooling was presented. In combination with experimental results of crystal growth pattern and solidification structure in selected alloys, the mechanisms for grain refinement in undercooled single-phase alloys and anomalous eutectic formation in undercooled eutectic alloys were then discussed.
