Research Abstract

High reliable bonding process in aluminum alloy/steel dissimilar joining based on analysis of interfacial nanostructure and its characteristic evaluation has established, and the application of the obtained knowledge to the conventional bonding method for automobile was performed. The formation mechanism of interfacial reaction layers has clarified and the improved method has established by controlling alloying elements. Joint property in micrometer scale was evaluated and its deformation behavior was basically identified using nanoindentation measurement and micro-tensile test. The application of the obtained results to the conventional bonding method has given the suitable interface which fracture occurs in aluminum matrix.
