In this study Ni and Ti with 50 at. % Ni powders were milled and the cylindrical performs obtained by uniaxial cold compaction under 150 MPa pressure. Porous Ni/Ti specimens were synthesized by thermal explosion (TE) at different preheating temperatures (350 °C, 400 °C, 500 °C and 600 °C) and milling times (0.5, 1 and 2h). The effect of preh­­­eating temperatures and milling times on microstructure of final products were investigated by X-ray diffraction analysis (XRD), optical microscopy and scanning electron microscopy (SEM). NiTi shape memory alloy with other secondary intermetallic compounds and elemental powders were observed in the final products. Results showed the dominant phase was NiTi in the sample that milled for 1h and preheated at 400 °C.
