| 摘 要： | 基于合金枝晶凝固微观偏析统一模型,导出一种新的描述三元合金单相凝固路径的解析模型.该模型具有统一性,不仅可涵盖平衡、非平衡和准平衡3种极限凝固路径模式,而且可考虑任意凝固相的反扩散、冷速和枝晶几何形貌等因素的影响.通过对Al-1.0Cu-6.3Mg,Al-1.49Si-0.64Mg和Al-1.49Si-2.90Mg(质...

| Abstract: | Accurate prediction for the solidification path of a multicomponent alloy and the amounts of the secondary phases presented under a given solidification condition is critical in understanding and controlling the performances of the solidified alloy materials/parts.The degree of freedom of a single-phase solidification in multicomponent alloys is at least more than one,whilch brings some difficulty in accurate predicting of the solidification path.A new analytical model for predicting a single-phase solidifi... |
