| Abstract Scope |
The medical device industry places unique demands upon materials, such as high fatigue resistance and biocompatibility, grade 2 Titanium being a ubiquitous example. A promising new(er) material, Vitreloy 105 has several attractive properties including high strength, corrosion resistance, low density and near net shape molding. A variety of techniques were utilized to optimize the welding schedule, but the focus here is on an optimized weld pool that creates an opportunity to explore non-equilibrium, titanium containing, microstructures. Using micro-cantilever experiments in a mapped weld pools. Zirconium particle rich regions toughen the cantilevers, when compared to bulk Vitreloy 105. These same regions exhibit extremely high strengths.
