Porous TiZr alloys by dealloying of Ti20Zr20Cu60 precursor in Mg melt for biomedical applications

This research aims to develop porous titanium–zirconium alloy for implant applications by the liquid metal dealloying method. The results indicated the formation of a homogeneous three-dimensional porous morphology with a density of 3 ± 0.3 g/cm 3 . The XRD analysis shows that the porous titanium–zirconium alloy is a single-phase hcp solid solution. The unique porous scaffold can be introduced as a promising candidate for dental implants owing to bone-like elastic modulus of 3.5 GPa and compressive strength of 550 MPa. The Ashby-type diagram confirms the achievement of new biomaterial with a good combination of high strength and low stiffness.
