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 NixTi100-x can be amorphized with 40≤x≤60.
Key words: mechanical alloying Ni-Ti alloys amorphization
