Y-TZP/TiNi composites were successfully fabricated by reductive sintering process. Mechanical properties of Y-TZP / TiNi composites were much higher than those of Y-TZP monolith. XRD analysis revealed that TiNi-base intermetallic compounds such as Ni4Ti3, NiTi, Ni3Ti had been formed. Moreover, the electrical resistivity characteristics indicated that Y-TZP/TiNi composites were a good conductor of the electricity.
