【Abstract】 Al-Fe-V-Si heat resistant alloys prepared by rapid solidification exhibit excellent thermal stability which can be ascribed to the obtained second phase particles of fine dispersoids and with low diffusibility.This paper reviewed the development history of Al-Fe-V-Si alloys.The preparation processes,microstructural control and strengthening measures were especially introduced.The problems met in the development of the alloys were analyzed emphatically and the future development should be focused on the optimization of process and the improvement of thermal stability.更多还原
