Abstract

An investigation has been made of the mechanical behavior of adispersoid strengthened,powder metallurgy Al-Fe-V-Si alloy at ambient tempera-lure and 250℃,The results show that the tensile ductility and fatigue life ofthe alloy decrease with the increase of temperature from room temperatureto 250℃,Observations by SEM indicate that the change of the mechanicalbehavior with temperature is related to the transformation of the fracture modefrom transgranular to intergranular,which is assumed to be due to differe...
