Methods for directionally recrystallizing additively-manufactured metallic articles by heat treatment with a gradient furnace

A method for manufacturing a metallic article includes providing or obtaining a metallic material in powder form, using an additive manufacturing process, building the metallic article from the powder-form metallic material, layer-by-layer, in a build direction, wherein as a result of the additive m...
