Abstract
Titanium and its alloys are extensively used as biomedical implant materials because their good mechanical properties are accompanied by an excellent biocompatibility and corrosion resistance. However, the most widely used Ti alloy for medical implants, Ti–6Al–4V, does not satisfy a major requirements about non-toxicity and low elastic modulus close to that of cortical bone. Therefore, alternative titanium-based biomedical alloys with other alloying elements are currently the subject of intensive study. This work was conducted to develop new as-cast Ti-based alloys with biocompatible elements, i.e. chromium and niobium addition and low elastic modulus. For this purpose six Ti–Cr–Nb alloys were prepared and their properties were evaluated. The obtained results indicated that experimental alloys have α/β microstructure. Among them, alloys Ti 70Cr 10Nb 20, Ti 70Cr 20Nb 10 and Ti 60Cr 20Nb 20 have very low elastic modulus (17–50 GPa), high strength (1580–1700 MPa) and plasticity (75.0–83.5%) as well as an excellent corrosion resistance. According to the obtained results it could be considered that new biomedical alloys with adequate properties for biomedical applications were developed.
