خلاصه مقاله:
In this work the possibility of synthesis of amorphous phase in Ni-Ti binary system by mechanical alloying (MA) was investigated. Also, formation of B2-NiTiparent phase by crystallization of amorphous phase, and finally production of the nanostructured or fine grain parts during sintering stepwere examined.Phase transformation and amorphization were investigated by X-Ray diffraction, differential scanning calorimetry and scanning electron microscopy. Nanocrystaline B2- NiTi phase is formed in the early stage of the sintering due to crystallization of amorphous phase. However byincreasing of the sintering temperature, the amount of B2-NiTi was decreased and almost replaced by Ni3Ti and Ti2Ni. So the reasons of this phase transformation were investigated
