Abstract:

With the steady development of science, technology and economy, application of single structural material cannot meet the demanding requirement for lightweight, multifunction, and integrity in extreme service conditions. This has become an ever-increasing challenge facing technology-intensive industries including aerospace, aviation and nuclear power.  Application of welded structures of novel materials and/or dissimilar materials could maximize the respective materials performance advantages, and therefore has been of great significance to the manufacturing industry. In the past twenty years, the Harbin Institute of Technology research team has conducted extensive research in the field of brazing and special joining. This report has provided a comprehensive summary of the team’s significant research progresses and achievements, including: 1) In-situ strengthening and stress relief of ceramic/metal joints, 2) Design and Application of Green Low-melting Glass Brazed Joint, 3) Low temperature bonding and high temperature application of advanced ceramics, 4) Joining techno logy of dissimilar metal, 5) Ultrasonic Additive Manufacturing (UAM) technology of laminated metal composite.
