Abstract：
The preparation of Al-Ti-B intermediate alloys by step melting preparation,reaction temperature and reaction time were studied,and the effects of reaction temperature and reaction time on the number,size and distribution of TiAl3 and TiB2 phases in al TiB intermediate alloys were studied by means of metallography,SEM and XRD.The results show that the Al-Ti-B intermediate alloy prepared by step melting method at 800℃has fine effect,TiAl3 phase is dispersed in(Al)matrix,while TiB2 phase is small in number and size,so it is difficult to find specific particles.The preparation of Al-Ti-B intermediate alloy by this method needs to further improve the temperature of the reaction,which can be used as a reference for further research on the preparation process.
