Abstract
ABSTRACTThe effects of internal hydrogen on the mechanical properties of Ti Code 12 were studied by gas phase charging smooth bar tensile samples. Tensile tests showed no change in yield strength with increasing hydrogen concentration. A slight decrease in ductility and fracture stress at hydrogen concentrations above 200 wppm accompanied by secondary cracking along grain boundaries indicated embrittlement. At hydrogen concentrations near and above 400 wppm, cleavage fracture associated with strain-induced hydrides was also observed.
