Abstract
The present study investigated the mechanical performance of Ti–8Nb–8Zr–8Cu (at.-%) alloys containing different porosity levels. Metallographic examination and phase analysis of samples was performed by scanning electron microscope (SEM), optical microscopy (OM), energy dispersive spectrometry (EDS) and X-ray diffraction (XRD) measurements. The mechanical properties were detected by uniaxial compression test, micro and macro hardness measurements. The wear behaviour was determined by a dry wear test on the bulk sample. The ultimate compressive strength decreased from 1077.30 to 344.65 MPa with 50% porosity and the modulus of elasticity from 15.6 to 9.5 GPa. These values show that it may be suitable for bone replacement considering the stress shield effect.
