undercooled melt

基本解释

The influence on the growth morphology of the spherical crystal in the undercooled melt imposed by the far field flow is studied by the asymptotic method.
利用渐近分析方法研究了远场来流引起的对流对过冷熔体中球状晶体的生长形态的影响。
The affecting law of structure fluctuation and energy fluctuation on dendrite growth in pure undercooled melt was studied by simulation of a phase-field method.
采用捕获液态界面改进的相场方法，系统地研究了结构起伏、能量起伏对过冷纯金属熔体中树枝晶生长的影响规律。
The grain refinement mechanisms of undercooled DZ125 superalloy melt were systematically investigated by the method of molten salt purification combined with cycled superheating.

过冷熔体
Experience shows that when a eutectic alloy melt is undercooled below its liquidus, metastableliquid phase separation takes place. Basically, undercooled melt separates into two differentregions from one homogeneous liquid.
在对金属的晶粒细化研究中发现,过冷熔体会发生亚稳液相分离现象,即从一个成份均匀的液相分离为两个成分不同的液相。
