| Abstract: | The current status of research work on intermetallic compound dispersoid in rapidly solidified elevated temperature aluminum alloys is reviewed.The dispersoid existing in common elevated temperature aluminum alloys, effect of rapid solidification processing on the formation of dispersoid and their thermal stability are discribed. The relationship between the volume fraction, distribution, shape of dispersoid and the normal, elevated temperature mechanical properties of aluminum alloys is outlined briefly in this paper. |
