High-strength Ti Alloy Prepared via Promoting Interstitial-Carbon Diffusion

Abstract

Feasibility studies are performed to determine the suitability of a novel simple synthesis technique for fabricating a new Ti alloy with improved strength and ductility, while exhibiting lower cell toxicity. Through consolidating pure Ti powders under a C atmosphere at elevated temperatures, a bulk form of the Ti alloy, in which a quantifiable amount of C is dissolved, is synthesized. While the alloy is free from toxic elements such as Al and V, the strength and ductility of the developed alloy are comparable to, or better than, those of its commercial Ti-6A1-4V alloy counterpart. In this study, the method to design the alloy, its synthesis, and the resultant properties are reported.
