A nanocrystalline layer was synthesized on the surface of TWIP steel samples by surface mechanical attrition treatment (SMAT) under varying durations. Microhardness variation was examined along the depth of the deformation layer. Microstructural characteristics of the surface at the TWIP steel SMATe...

采用真空熔炼法制备了Fe-20Mn-XCu-1.3C系高强度高塑性合金钢。通过单向拉伸试验和OM观察，研究了铜含量的变化对该合金微观组织和力学性能的影响。结果表明：Fe-20Mn-XCu-1.3C系合金拉伸变形前后均为单相奥氏体组织。随着铜含量的增加，合金的屈服强度和伸长率提高，而抗拉强度降低，Fe...
