Abstract: Based on the previous work on the mechanical alloying of Ni-Al-Ti compounds. the mechanically alloyed Ni-Al-Ti compounds was characterized. The results show that with the increase of Ti content. the microhardness of the final products decrease apparently. The thermal behavior of the resultant Ni-Al-Ti compounds shows significant difference, the as-milled powders with different Ti content transform into different products after healing.So the microstructure of the milled alloys could be determined through adequate control of composition and heat treatments.

Key words: mechanical alloying. Ni-Al-Ti, properties
