Abstract Scope |
The MoNbTaTiZr high entropy alloys are promising for biomedical applications because of the excellent biocompatibility of constituting elements. In this work, MoNbTaTiZr medium and high entropy alloys with varying amount of Mo and Ta have been examined systematically. Whereas an increase in the yield strength is observed as a function of Mo and Ta content, however, their addition more than a critical value causes brittleness. This study accomplishes an optimum alloy system for biomedical applications, and then it was analyzed using cell culture and in-vivo biocompatibility evaluation in thigh muscles of mice. The alloy has shown strong osseointegration to osteoblasts and non-toxic response to muscular tissues. |
