Manufacturing For Design of Titanium Alloys

This SBIR Phase I program proposes to exploit the tremendous benefits that could be offered by the development of a microstructural refinement and control technology for titanium alloys. A severe plastic deformation (SPD) technology based on hot die isothermal forging technologies will be explored in this work. The goal is to demonstrate a practical, production level manufacturing approach to producing bulk-sized titanium alloy components with refined and controllable microstructure-properties. Higher performance titanium alloys would be particularly advantageous for next generation airframe and engine structures and components seeking improved structural efficiency. The effect of different thermomechanical conditions to achieve the requisite microstructure-properties also needs to be understood in order to identify the optimum process. More »
