铝基复合材料中,增强体的加入使金属凝固过程的形核、晶体生长、溶质分配和流体流动行为发生改变,特别是在不同压力和冷却条件下的非平衡凝固状态下。从而对基体组织的形态、二相析出、溶质偏聚、界面反应性、凝固缺陷等产生重要影响,最终影响复合材料的性能。基于此,综述了凝固过程对铝基复合材料组织与性能的作用规律。 In aluminum matrix composites, the addition of reinforcements changes the nucleation, crystal growth, solute distribution and fluid flow behavior during the solidification process, especially under the conditions of non-equilibrium solidification under different pressures and cooling conditions. Thus affecting the morphology of the matrix, the precipitation of two phases, the solute segregation, interface reactivity, and solidification defects, which ultimately affect the properties of the composites. Based on this, the effects of solidification process on the microstructure and properties of aluminum matrix composites were reviewed.
