Abstract

TiNi bodies were produced from (Ti+Ni) powder mixture by spark-plasma sintering process. The sintering behavior was investigated through the measurement of change in density, densification rate, phase analysis and microstructure. Irrespective of heating rate, sintered bodies with above 97% relative density could be obtained. TiNi with B2 structure was confirmed as the major phase and Ti2Ni, TiNi3, unreacted Ti, Ni as the second phase. Increase in heating rate suppressed a formation of intermediate phase during sintering process. Increase in holding time at sintering temperature led to a compositional homogenization.
