| Abstract Scope |
Although the powder metallurgy (PM) of Ti has shown promise to be a low cost approach, it has not gained significant market acceptance because the performance-to-cost ratio of PM Ti cannot compete with that of wrought Ti. In order to compete, the cost of Ti powder must be drastically reduced and the mechanical properties of PM Ti must be drastically improved. This presentation introduces both a low cost powder production process and a sintering technology that can produce Ti-6Al-4V with wrought-like microstructure and mechanical properties. This talk will present elaborate the design of the hydrogen assisted Mg reduction (HAMR) process and the results that demonstrate HAMR process can produce low oxygen Ti powders. The second part of this presentation introduces the hydrogen sintering and phase transformation (HSPT) process which designed to produce Ti-6Al-4V alloy with wrought-like microstructure and mechanical properties via simple press-&-sintering and heat treatment. |
