Why is it important?
This research, other than discussing the effects of hardening treatment on the microstructure, phase composition and mechanical properties of as-sintered parts, investigates the relation between the microstructure and the mechanical properties of hardened 60NiTi parts containing different amounts of open porosity. In addition, the suitability of using these porous structures for general bone replacement applications, in terms of microstructural, mechanical and chemical properties, is discussed in this research.
Perspectives
As an outcome, biocompatible corrosion resistant solutionized 60NiTi parts with different amounts of open porosity were generated in this research. All these samples fulfilled the strength and stiffness prerequisites for biomedical applications. However, the samples did not show adequate fracture elongation. Further, only solutionized samples processed under one particular set of conditions considered in this work achieved the ∼30 vol% open porosity suitable for biomedical applications.
