브레이징을 이용한 Ti/SUS321L 접합체의 기계적 특성과 미세조직의 변화

Variations of micro-structures and mechanical properties of Ti/SUS321L joint using brazing method

This study is investigated in variations of micro-structures and mechanical properties of Ti/SUS321L joint with bonding temperature and time using brazing method. According to increasing bonding temperature and time, it was observed the thickness of their reaction layer increased. In tensile test, it was examined that the tensile strength had maximum value at the bonding time of 5min and decreased after bonding time over 5min because of increasing their oxides and intermetallic compounds.
