| Abstract Scope |
Metallic biomaterials, due to their excellent mechanical properties, are widely used to replace or support the failed hard tissues. Stainless steels and conventional CoCr alloys boast high strength, but their Young’s moduli are much greater than that of human bone, which is considered to result in bone atrophy due to the stress shielding effect. Whereas a low Young’s modulus can be found in the β-type Ti-based alloys, they come with a compromise of low wear resistance. In this poster, the recently developed CoCr-based Co-Cr-Al-Si (CCAS) alloys are introduced. The CCAS alloys exhibit a low Young’s modulus similar to that of human bone, and their wear resistance is also high. Further, these alloys show superelasticity with a huge recoverable strain up to 17%, which is twice larger than that of the conventional NiTi alloys. |
