“…The metallurgical bond between Q345 and the WM is satisfactory in comparison, as shown in Figure 2b. This finding has been confirmed by several previous studies [18,28]. The tensile test results of Li et al [18] showed that the fracture occurred at the TC4/WM interface, while the steel/WM interface exhibited superior metallurgical bonding.…”

Additionally, at the Q345/WM interface, the fracture appears as a dimple rather than a brittle cleavage pattern [28].…”

Due to the notable disparities in the physical and chemical characteristics between titanium and steel, the direct fusion of titanium/steel bimetallic sheets results in a considerable formation of fragile intermetallic compounds, making it difficult to achieve excellent metallurgical welded joints. In this study, a multi-principal powder of CoCrNiMn was designed and utilized as a filler material in the welding of the TA1/Q345 bimetallic sheet. It was expected that the in situ formation of Fex(CoCrNiMn)Tiy high-entropy alloys would be achieved using the filler powders, combined with the Ti and Fe elements from the melting of the TA1 and Q345 so as to restrain the generation of Fe-Ti IMCs and obtain the promising welded joints of the TA1/Q345 bimetallic sheet. An interesting finding is that high-entropy alloys were successfully obtained in the weld metal. The Fe-Ti intermetallic compounds at the welding interface were significantly reduced. The tensile strength was ~293 MPa, accounting for 60% of the strength of the base metal. Dimples were observed at the fracture of the welded joint.
