The rapid solidification of an AL-10wt%Si-Sc alloy

合金凝固是与铸造和表面处理相关的许多现代实验技术和工业技术中出现的一种复杂现象。不同的凝固条件(如过冷或冷却速度)的变化使控制晶体结构的形态和尺寸成为可能，这对合金的物理和化学性能有很大的影响。特别是，合金的深度过冷低于平衡液相线和共晶会导致快速凝固，并产生具有更好的机械、磁和电性能的材料。拟议的3年项目是Equisphes和大学之间的合作项目。艾伯塔省。我们将使用脉冲雾化(IA)-一种单流体快速凝固技术来产生粉末样品。将产生Al-Si(Sc)合金。由于过冷，后者有望在阿尔法矩阵中过饱和。固化的样品将被

Solidification of alloys is a complex phenomenon arising in many modern experimental techniques and industrial technologies related to casting and surfaces processing. The variation of different conditions of solidification (such as undercooling or cooling rate) gives a possibility to control the morphology and size of crystal structure, which substantially influence physical and chemical properties of alloys. In particular, deep undercooling of alloys below equilibrium liquidus, and eutectics results in rapid solidification and yields materials with improved mechanical, magnetic and electrical properties. The proposed 3 year project is a collaboration between Equispheres and the Univ. of Alberta. We will generate powder samples using Impulse Atomization (IA) - a single fluid rapid solidification technique. Al-Si (Sc) alloys will be generated. The latter is expected to be supersaturated in the alpha matrix due to undercooling. The solidified samples will be
