英文摘要	An ingenious thermo-mechanical treatment process was utilized on a Fe-5.95Mn-1.55Si-1.0Al-0.055C medium-Mn steel to investigate the effect of fibrous 3-ferrites on mechani-cal properties. With a large enough cold-rolling reduction ratio (~70%), the morphology of coarsened fibrous 3-ferrites is tailored into homogeneous distributed fragments, which provides a precondition to launch the present study. Direct experimental evidence has been obtained that fibrous 3-ferrites are a double-edged sword for mechanical properties: it improves ductility (by 3.5% +/- 1.1%) but decreases tensile strength (by 65 +/- 11.5 MPa). This can be related to the accommodation effect of dislocations within coarsened fibrous 3-ferrite grains as soft phase, which decreases the degree of dislocation pile-ups in martensitic matrix, resulting in the limited strengthening effect of dislocations. Addi-tionally, despite significant directionality along rolling direction, the fibrous 3-ferrite grains do not result in anisotropic properties.(c) 2022 The Authors. Published by Elsevier B.V.
