Process-microstructural features for tailoring fatigue strength of wire arc additive manufactured functionally graded material of SS904L and Hastelloy C-276

[Display omitted] •WAAM process was successfully used to fabricate FGM of SS904L/Hastelloy C-276.•Heterogeneous microchemistry along the built-direction is attributed to the complex cyclic thermal history.•FGM tensile samples fractured with sufficient plastic deformation and tensile strength higher...
