Effects of process parameters on interfacial characterization and mechanical properties of 316L/CuCrZr functionally graded material by selective laser melting

•The 316L/CuCrZr FGM is successfully fabricated by SLM.•Effects of laser power and scanning speed on the CuCrZr track stability on 316L substrates are discussed.•Relationship between the cracks on 316L region and the process parameter is investigated.•The UTS of the vertically and horizontally integrated 316L/CuCrZr FGM are 318.2 ± 7.2 MPa and 519.8 ± 6.2 MPa, respectively
