This Small Business Innovation Research Phase I project will focus on the development a new family of nanoengineered low-alloy steels that surpass the state-of-the-art in coupling high strength (2,000 MPa tensile strength) with high elongation (20%). The outcome of this project will be the creation of a domestically-designed and produced, and lower cost advanced high strength steel (AHSS), based on a low alloy chemistry and lower energy intensity manufacturing process. The commercialization of a non-commodity fourth-generation AHSS family of structural materials with ultrahigh strength, and toughness without sacrificing elongation will provide significant value for the U.S. steel makers. These cost-effective low-alloy steels could displace current AHSSs and other exotic materials, such as aluminum, metal or ceramic matrix composites, and fiber reinforced composites to be used in a variety of applications in the Defense, Off-Highway, and Automotive industries. Furthermore, the proposed manufacturing technique can be easily retrofitted to current steel plate and sheet production lines with minimal new equipment. The U.S. market for AHSS is in excess of $5 billion and is expected to double within the next five years. Current advanced high strength steels (AHSSs) employ high alloy content, increasing their cost, and feature trade-offs between strength and ductility. A new steel manufacturing process will be developed, combining a patented ultra-high strength steel austempering process with grain deformation, nanostructuring the steel to deliver high elongation. The nanoengineering deformation and heat treatment processes for the proposed fourth-generation steel have been proven in the laboratory and have greatly improved structural performance. Other industrial steel grain nanostructuring means have shown improvements in tensile strength, but have exhibited low elongation, and their manufacturing methods have not been easily translated to sheet production. It is anticipated that the proposed manufacturing process can be used to make plate, sheet, and net-shape steel products. Completion of this effort will result in a technical model to optimize steel properties, a series of prototype steels, and the design of a prototype manufacturing line which can be scaled in Phase II to penetrate the multi-billion dollar AHSS market.

这个小型企业创新研究第一阶段项目将专注于开发一种新的纳米工程低合金钢系列，这种钢在结合高强度(2,000兆帕拉伸强度)和高伸长率(20%)方面超过了最先进的水平。该项目的成果将是创造一种国内设计和生产的、基于低合金化学和低能源强度制造工艺的低成本先进高强度钢(AHSS)。非商品化的第四代AHSS系列结构材料具有超高的强度和韧性，而不牺牲延伸率，这将为美国钢铁制造商提供重大价值。这些具有成本效益的低合金钢可以取代当前的AHSS和其他外来材料，如铝、金属或陶瓷基复合材料，以及纤维增强复合材料，将在国防、非公路和汽车行业的各种应用中使用。此外，建议的制造技术可以很容易地改造到现有的钢板和薄板生产线，而只需最少的新设备。美国的AHSS市场规模超过50亿美元，预计在未来五年内将翻一番。目前先进的高强度钢(AHSS)使用高合金含量，增加了成本，并在强度和塑性之间进行了权衡。将开发一种新的钢铁制造工艺，将获得专利的超高强度钢等温淬火工艺与晶粒变形相结合，使钢具有纳米结构以提供高延伸率。提出的第四代钢的纳米工程变形和热处理工艺已在实验室得到验证，并极大地改善了结构性能。其他工业钢颗粒纳米结构方法在抗拉强度方面有所改善，但伸长率较低，其制造方法不易转化为板材生产。预计所提出的制造工艺可用于制造板材、薄板和净型钢产品。这项工作的完成将产生一个优化钢材性能的技术模型，一系列原型钢，以及一条原型生产线的设计，该生产线可以在第二阶段进行规模扩大，以渗透数十亿美元的AHSS市场。
