摘要

The effect of carbon content on the precipitation and distribution of intermetallic compounds in titanium to decarbonized carbon steel brazed joint was studied. In this work, decarbonization treatment was employed to change the carbon content in the low carbon steel surface and thus influence the diffusion behavior of Ti and Fe elements in the joint. The microstructure, fracture surface and bonding strength of joints were detected by SEM/EDS, XRD and shear strength test. As a result, rich-carbon state in the steel surface profited the bonding of dissimilar joint to some extent during brazing process. TiC generated near carbon steel side can improve the bonding strength of joints by hindering the precipitation of FeTi and Fe2Ti. Precipitation and distribution of TiC, FeTi and Fe2Ti intermetallic compounds in joints were investigated.
