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.
