Intermetallics TiAl alloy is one of the most promising materials for new generation high tempera-ture structural application due to the properties of low-density and high temperature.The development, research status,effects of alloying elements and microstructure control technologies of TiAl alloys were reviewed.At present,the low room temperature ductility,insufficient high temperature strength and high cost of manufacture were the main problems.The practical method to improve the comprehensive mechani-cal properties was multi-component alloying and accurate microstructure control,which was also the impor-tant research field of TiAl alloys in the future.
