Ternary Ni-Al-Fe alloys with different Fe-additions have been synthesized by mechan ical alloying.The results show that 5 and 10 at% Fe-additions prolong the milling time prior to the explosive formation of NiAl(Fe) compound, 15 at.% Fe-addition results in the formation of an "amorphous-like" phase,20 at.% Fe-addition turns the final products to Ni(Al, Fe)supersaturated solid solution with fcc structure,and the increase of Fe-addition can speed up the formation of the solid solution.The addition of Fe improves the plastic deformation ability of the alloys.
