SCIENTIFIC PRINCIPLES OF THERMAL HYDROGEN TREATMENT OF TITANIUM-ALLOYS

The scientific principles of thermal hydrogen treatment of titanium al loys have been presented. The basic technological processes have been described based on controlling the phase formation in hydrogen alloyed materials. Thermal hydrogen treatment has been shown to affect the st ructure and mechanical properties of as-cast and strained semi-product s and weld joints of different titanium alloys. The most promising app lication fields of the hydrogen technology of titanium alloys have bee n considered.
