Grain refinement and crack inhibition of hard-to-weld Inconel 738 alloy by altering the scanning strategy during selective laser melting

Additive manufacturing of hard-to-weld nickel-based superalloys leads to the formation of elongated columnar grain structures and hot cracks along the build direction. Changing the scanning strategy during selective laser melting (SLM) without changing alloy composition is a promising method for the...
