| 英文摘要 | A hybrid nanostructured surface layer has been produced on interstitial-free steel by means of surface mechanical rolling treatment and subsequent chromizing treatment. The near-surface layer consists of Cr-enriched grain boundary zones enclosing ultra-fine grains (GBZ-UFG structure), and the subsurface layer consists of nanograins with increasing size along depth (gradient structure). Uniaxial tension measurements revealed that the yield strength is doubled while the uniform elongation increases similar to 24.5 % in hybrid nanostructured samples compared with in coarse-grained counterparts. Investigations on microstructure and straining mechanisms demonstrated that the unique GBZ-UFG structure enhances the deformation hardening capability and ductility in the near- surface layer, contributing to the significantly enhanced strength-ductility synergy together with the enhancement by the gradient structured subsurface layer. This work developed a novel grain boundary engineering strategy to manipulate mechanical properties of metals. |
