用XRD、TEM和EDX分析确认:快凝Al-8.47Fe-1.26V-1.67Si合金在高温时效后,显微组织由.ffcα-Al和bccα-Al13(F3,V)3Si弥散纳米粒子组成.后者的粗化动力学规律符合体扩散控制的LSW机制.在427和482℃高温状态下的界面能分别为0.185和0.245J·m-2,即α粒子与基体间存在非共格关系
It was showed that the microstructure was composed of α-Al and α-Al13(Fe, V)3 Si phases af ter high-temperature annealing treatment for RS Al-Fe-V-Si Alloy by means of XRD, TEM and EDX analysis. The coarsening kinetics of the particles is in agreement wit
