摘要：
The weldability and mechanical properties of IC10 single crystal and GH3039 superalloy dissimilar laser beam welded joint was investigated. The results showed that the dissimilar materials joint was obtained by laser beam welding. The crack sensitivity was reduced in dissimilar weldment. The tensile strength of the dissimilar welded joint is 602 MPa.
