Abstract

The design of a precipitation-strengthened, superelastic, biomedical alloy for the application of endovascular stenting demonstrates the effectiveness of models for aluminide precipitation-strengthening, transformation temperature, interphase misfit, and radiopacity. While earlier research focused on the role of zirconium in these alloys, current research quantifies the role of palladium. A newly designed Ni20Pd30Ti46Al4 (at.%) alloy that is superelastic at body temperature demonstrates greatly enhanced thermal and mechanical cyclic stability over binary TiNi.
