超高碳钢 (UHCS) 是含碳量 1-2.1% 的低合金普碳钢。这些钢在经过加工以获得具有细小球状碳化物的细铁素体晶粒时具有显着的结构性能。它们可以在中间温度下制成超塑性。此外，它们可以在环境温度下变得坚硬且具有压缩韧性并且坚固且具有良好的拉伸延展性。与传统观点相反，UHCS 是目前使用的高碳（0.5-1% 碳）钢的理想替代品，因为它们具有相当的延展性，但强度和硬度更高。在本文中，举例说明了由细晶粒球化 UHCS 形成的结构部件的示例，并回顾了其他潜在的结构应用。这些钢可以与其他金属基材料层压，以实现超塑性、高抗冲击性、极高的拉伸延展性和改善的疲劳行为。
Ultrahigh-carbon steels (UHCSs)are low-alloyed plain carbon steels containing 1-2.1 % carbon. These steels have remarkable structural properties when processed to achieve fine ferrite grains with fine spheroidized carbides. They can be made superplastic at intermediate temperatures. Further, they can be made hard with compression toughness and strong with good tensile ductility at ambient temperatures. Contrary to conventional wisdom, UHCSs are ideal replacements for currently used high-carbon (0.5-1 % carbon) steels because they have comparable ductility but higher strength and hardness. In this article, examples of structural components formed from fine-grained spheroidized UHCSs are illustrated, and other potential structural applications are reviewed. These steels can be laminated with other metal-based materials to achieve superplasticity, high impact resistance, exceptionally high tensile ductility, and improved fatigue behavior.
