【摘要】 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更多还原

【Abstract】 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 with the LSW type volume diffusion control-led process. In addition, the calculated particle / matrix interfacial energies are 0. l85, 0.245J. mw-2at 427 and 482℃, respectively, which proves the experimental result of the incoherent precipitate / matrix interfacial re-lationship.更多还原
