Abstract Scope |
Owing to the ageing of the population, the need for medical implants in orthopaedic and dental interventions has been significantly increasing in recent years. Traditionally metallic implants and devices may present various limitations such as adverse corrosion, wear and fatigue behaviour, manufacturing challenges, toxicity of alloying elements and high elastic modulus causing the undesirable stress shielding effect. Multi-principal element alloys provide an excellent opportunity to develop the next generation of biocompatible alloys. Using appropriate alloy design strategies and thermodynamic calculations, medium and high entropy alloys were developed with attractive combinations of low elastic modulus, biocompatibility, corrosion resistance, mechanical strength and ductility. Here we focus on the relations between chemistry, structure and mechanical properties of a series of bio-MEAs and bio-HEAs and we present an overview of challenges and future opportunities. |
