Abstract
Although high hydrogen levels in metals can have a devastating effect on mechanical properties, many positive effects can also be derived from high solubility. The use of hydrogen as an energy storage device and as a means of detecting overheating/fires in jet engines are two positive effects. Thermochemical processing (TCP) (use of hydrogen as a temporary alloying element) can also strongly enhance processing behavior and final component characteristics of titanium based alloys. This paper reviews processing using TCP, including wrought product, powder metallurgy (PM) materials, and superplastic forming. The refinement of the microstructure and improvement in mechanical properties achievable using TCP is presented for wrought product, PM material and castings; the latter product form offering the largest improvement compared to conventional material. The state of our knowledge of the mechanism(s) by which TCP enhances processing and final mechanical properties is reviewed.
