Physicomechanical properties of porous titanium nickelide

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The insufficiently high degree of perfection of interparticle contacts at high homologous sintering temperatures of titanium nickelide is related to specifics of its superelastic behavior and is explained by rupture of the contact bonds formed in pressing during preparation of the material.

In the 30–50% porosity range, which is most important for providing a high level of reversible deformation, the quality of interparticle contacts has the prevailing influence on porosity.

The unsteady (with a maximum) character of the relationship of deformation until fracture to porosity is related both to nonuniformity of deformation of porous titanium nickelide and to specifics of deformation according to the martensite transformation mechanism.
