Abstract Scope |
Prudent materials selection is vital in the success of a bioimplant. Biocompatibility, degradation in bio-media, and osteopenia are all important considerations in the design of biomaterials fit for function. By combining the existing alloy design strategies based on bond order and d-orbital electron theory with additional considerations such as cytotoxicity, we designed a complex concentrated alloy. The issue of microstructural heterogeneity was addressed by severe plastic deformation processing. The designed alloy MoNbTaTiZr exhibits superior biocorrosion and mechanical property profile for use in orthopedic implant applications as compared to available bio-inert metallic alternatives such as surgical stainless steel (SS316L) and Titanium (Ti-6Al-4V) alloys. By exploring the design space of high entropy alloys and addressing primary concern of elemental segregation, this work provides a new avenue for the facile design and development of similar alloys for structural implant applications. |
