采用等通道转角挤压（ECAP）工艺对高强度超细晶低碳钢进行不同道次的挤压，并对其进行热处理，使其抗拉强度达到1400- 1500 MPa。系统地研究了其显微组织和力学性能，特别是疲劳性能。结果表明，单道次ECAP可以同时提高材料的抗拉强度和延伸率，两道次ECAP可以获得最佳的疲劳强度460 MPa，但进一步增加ECAP道次会使材料的疲劳性能变差。因此，结合热处理效果和疲劳损伤机理，提出低碳钢在ECAP变形过程中，只需较少道次即可获得最佳的疲劳性能，为ECAP的工程应用提供了一种简便、经济、高效的方法。
High-strength ultrafine-grained low-carbon steel was processed by equal channel angular pressing (ECAP) for different passes and then heat-treated to achieve the tensile strength in the range of 1400–1500MPa. Then its microstructure and mechanical properties, especially fatigue properties were systemically investigated. It is found that the simultaneous enhancement of tensile strength and elongation can be obtained by only one ECAP pass; the optimum fatigue strength of 460MPa can be gained by two ECAP passes; while further increasing the number of ECAP passes made the fatigue properties worse. Therefore, combing with the effects of heat treatment and fatigue damage mechanism, it is suggested that few number of ECAP passes is enough to achieve the optimum fatigue properties for low carbon steel, which makes it easy, economical and efficient for the engineering application of ECAP.
