Material Optimization and Manufacturing Development of Reduced Cost Powder Metal Titanium Alloy Components for Gas Turbine Engine Application, Phase 2.

摘要

This Small Business Innovation Research (SBIR) program has demonstrated the economic benefits of the cold-hot isostatic pressing (CHIP) powder metallurgy (P/M) materials and manufacturing technology to produce lightweight titanium alloy components. Tooling was developed and a turbine engine bearing housing preform and a tank track pin were produced. The study also established a data base of the static and dynamic mechanical properties as a function of the chloride impurity level of the commercially available elemental titanium powders and their associated costs.
