Abstract

Additive manufacturing is an effective route for processing Ti alloys and producing materials with functional gradients. An interesting system for obtaining orthopedic biomaterials refers to Ti-Nb-Fe-Sn. In this system, Nb promotes the beta phase stabilization, Fe allows an increase in mechanical strength and Sn reduces the omega phase precipitation. This work aims to evaluate the effect of Sn addition on the microstructure and properties of Ti-Nb-Fe alloys prepared by additive manufacturing, aiming at the production of materials with functional gradients. It is also intended to verify the effect of aging heat treatment parameters on the microstructure and mechanical properties of Ti-Nb-Fe-Sn alloys. (AU)
