Direct laser deposition of Cu-Mo functionally graded layers for dissimilar joining titanium alloys and steels
Source abstract
Abstract
Abstract The dissimilar joining of titanium alloys and steel is more challenging due to the formation of brittle Ti-Fe intermetallic compounds (IMCs). The use of Cu-Mo interlayer successfully prevented the mixing of Ti and Fe to avoid the formation of FexTiy brittle phases. Near Ti-(Cu + Mo) interlayer boundary typical CuTi2, CuTi and Cu3Ti2 phases are formed. Intermetallic stoichiometry, morphology are discussed. The tensile strength of the Grade1/316 L joints with the Cu-Mo interlayer is 175 MPa, and the joints exhibited the ductile–brittle fracture. The fracture region formed at the interlayer along the molybdenum particles.
