Abstract

The effect of hydrogen charging on the electrochemical behavior, surface properties, and the cracking processes of Ti-6Al-3Nb-2Zr-1Mo (Ti80) alloy base metal and welded joint is investigated. Hydrogen promotes the deterioration of the Ti80 including the destruction of the passive film, formation of the hydrides, initiation of the cracks, and decrease of the mechanical properties. The weld metal show much higher susceptibility to hydrogen because of the finer grains with lamellar structure. Hydrogen embrittlement mechanism differs from the hydrogen introducing approach. The hydrides, internal hydrogen, and hydrogen-stress interaction play different roles in the hydrogen damage process of the Ti80 alloy.
