Abstract
Microstructure and mechanical properties of friction welded and vacuum brazed Ti/AISI
321 stainless steel have been evaluated with various welding conditions. Maximum tensile strength
of friction welded joints was approximately 420 MPa with the conditions of 400 MPa of upset
pressure (P2) and friction time (t1) within 2.0 s. Maximum tensile strength of brazed joints was
acquired under the condition of 900 °C brazing temperature and 5 min. brazing time and showed
approximately 275MPa which was about 80% of that of the Ti base metal. Friction welded Ti/AISI
321 joints showed the superior tensile strength than that of brazed Ti/AISI 321 due to thinner
intermetallic compound layer.
