Microstructural development during consolidation of rapidly solidified Al-Fe-V-Si powder by VHP, extrusion and rolling

The rapid solidification of powder results in a high cooling rate which leads to microstructural refinement and extended solid solubility of alloying elements and thereby precipitation of fine dispersive phases during powder solidification and consolidation. During the last decade considerable research work has been done in the development of high temperature powder metallurgy aluminum alloys capable of competing with titanium alloys on a specific strength basis with the use of rapid solidification processes. The Al-Fe-V-Si family of alloys are one of the most promising on a basis of elevated temperature strength, stiffness and thermal stability. In previous studies, the Al-Fe-V-Si alloys were usually produced by melt spinning (both jet casting and planar flow casting) followed by consolidation of the resulting ribbons. The aim of the present study was to investigate the microstructural development of atomized Al-Fe-V-Si alloy powder during consolidation by vacuum hot pressing (VHP), extrusion and rolling.
