Abstract

Porous TiNi bodies were produced by Self-propagating High-temperature Synthesis (SHS) method from a powder mixture of Ti and Ni. Porosity, pore size and structure, mechanical property, and transformation temperature of TiNi product were investigated. The average porosity and pore size of produced porous TiNi body are 63% and 216mutextrmm, respectively. XRD analysis showed that the major phase of produced TiNi body is B2 phase. Its average fracture strength and elastic modulus measured under dry condition were 22pm2 MPa and 0.18pm0.01GPa, respectively. It could be strained up to 7.3 %. The transformation temperatures determined by DSC showed the M_s temperature of 67°C and A_f temperature of 99°C.
