| Abstract Scope |
The Hydrogen Sintering and Phase Transformation (HSPT) process has been proven capable of producing fully dense Ti-6Al-4V with a range of application-tailored, wrought-like microstructures and mechanical properties using a simple press and sinter powder metallurgy (PM) process. This is achieved by utilizing a dynamically controlled hydrogen partial pressure during sintering, which both aids densification and allows for microstructural engineering through hydrogen-enabled phase transformations. HSPT has been previously shown to produce strength over 1 GPa with 22 %EL ductility and fatigue endurance limits consistently around 60% UTS (~600 MPa). Recent research has focused on the optimization of the HSPT process and subsequent heat treatments for further improvement of mechanical properties. Furthermore, combining of this process with other near-net-shape production techniques, such as additive manufacturing, has been explored. The results from these recent efforts will be discussed. |
