| Abstract | The tensile and fatigue behavior of a dispersoid strengthened, powder metallurgy AI-Fe-V-Si alloy at ambient and elevated temperatures was investigated. The results show that the strength and ductility of the alloy decrease significantly with increasing temperature and decreasing strain rate. Micro-structural examinations reveal that this change in mechanical behavior with increasing temperature is related to the mode of deformation of the alloy. Further observations show that localized shear deformation is responsible for the losses in both strength and ductility of the alloy at elevated temperature.; The tensile and fatigue behavior of a dispersoid strengthened, powder metallurgy AI-Fe-V-Si alloy at ambient and elevated temperatures was investigated.
