Abstract: NixTi(100-x) (x=10～70) alloys have been prepared by mechanical alloying of clemental titanium and nickel powders. X-ray diffraction, SEM and TEM were used to characterize structural changes of Ni₅₀Ti₅₀ milled powders. The crystallite size, microstrain and lattice parameter of nickel crystals were measured as a function of milling time, and DSC was used to examine the thermal properties of Ni₅₀Ti₅₀ milled powders. It is found that NixTi_100-x can be amorphized with 40≤x≤60.
