Abstract Scope |
Using appropriate alloy design strategies and thermodynamic calculations, medium and high entropy alloys were developed with BCC structures and attractive combinations of biocompatibility, corrosion resistance, low elastic modulus, high mechanical strength and ductility. Novel non-equimolar alloys were produced by arc melt- casting in an Ar inert atmosphere from simple to more complex compositions starting on the known refractory system TiZrNbTaMo. This work focuses on the relations between chemistry, structure and properties of the developed MEAs and HEAs. Further surface modifications can be carried out to bioactivate the alloys surfaces for improved interactions between the metallic bio-materials and the human tissue. The achieved combinations of bio-compatibility, electrochemical and mechanical properties indicate that Bio-HEAs are very promising for applications as implant materials. The enormous space for further development and optimization offered by the high entropy alloying strategies cannot be underestimated.
