| Abstract Scope |
Titanium alloys, such as Ti-6Al-4V, propose substantial benefits for cold spray applications by producing high strength parts and coatings at a reduced manufacturing cost; however, the alloy’s high yield strength challenges its ability to plastically deform and obtain high deposition efficiency. This work explores a matrix of thermal feedstock powder treatments to soften the microstructure of Ti-6Al-4V powder, directly improving its ability to cold spray effectively, while maintaining optimal mechanical properties. Virgin Ti-6Al-4V powder was heat treated to directly improve the deposition efficiency and mechanical properties of the cold sprayed specimens. Results indicate that heat treating virgin Ti-6Al-4V powders prior to deposition can achieve reduced strength, thus enhancing cold spray performance verified by an observed phase change and improved mechanical properties. The results of this work pave the way for future research into the optimization of titanium heat treating to achieve a superior microstructure that is advantageous for cold spray. |
