Abstract: Abstract Rapid melting and solidification cycles during laser-based additive manufacturing create non-equilibrium microstructures in stainless steels (SSs) including atomic segregation-mediated ultrafine δ-ferrite, in contrast to coarse δ-ferrite in typical casting-produced SSs. The formation of metastable… read more here.
