A sensitivity analysis of the columnar-to-equiaxed transition for Ni-based superalloys in electron beam additive manufacturing

[Display omitted] •Alloy design is not an effective approach for grain structure control in SEBM.•Liquidus slope has a moderate role in effecting the columnar to equaixed transition.•Nucleation density has the largest effect on grain structure in SEBM.•Processes parameters play a large role in shapi...
