项目摘要
This SBIR Phase II project will address the lack of high application temperature materials available for additive manufacturing. Additive manufacturing, often called 3D printing, provides increased design freedom and complex features such as part consolidation and conformal cooling channels. The performance and efficiency of gas turbines and other applications can be increased by combining design improvements enabled by additive manufacturing with a suitable high temperature material. Unfortunately, existing materials either do not have sufficient high temperature performance or are not compatible with high quality printing methods. This project will develop new nickel superalloy composite additive manufacturing materials for use with high temperature gas turbine components. Successful completion of this project will result in more efficient turbines to reduce energy costs, transportation costs, and carbon emissions. The manufacturing, power generation, and aerospace industries are expected to be impacted from this project. In addition, history has demonstrated that new materials and manufacturing technologies often lead to additional unexpected innovations. This project will help the country lead in the innovation of high performance materials technology to address the needs of the $86 billion gas turbine market and to grow advanced manufacturing jobs in the US.This project will utilize innovative reactive additive manufacturing materials technology to develop 3D printable advanced high temperature superalloys. During additive fabrication, high melting temperature product phases will be synthesized in-situ within a superalloy matrix to significantly improve high temperature performance and improve printability. This innovative reactive additive manufacturing technology has been shown to be applicable to a wide range of materials systems including nickel superalloys in an NSF Phase I project. Metal matrix composites produced using this technology have demonstrated greatly increased strength, wear resistance, and high temperature performance relative to comparable traditional alloys. In addition, this technology has demonstrated the ability to eliminate micro and macro cracking problems with alloys that had previously been considered unprintable. This project aims to further develop one or more high temperature superalloys compatible with laser powder bed fusion additive manufacturing for use in the hot sections of gas turbines. The scope of the project includes theoretical and experimental development and evaluation of novel material feedstocks, additive manufacturing processing conditions, and heat treatments. Evaluation of printed components will include measurement of density, hardness, standard and high temperature tensile properties, creep, and microstructure and phase analysis. Turbine components will be additively fabricated for pilot studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
SBIR二期项目将解决可用于增材制造的高温材料的缺乏问题。增材制造,通常被称为3D打印,提供了更高的设计自由度和复杂的功能,如零件固化和保形冷却通道。通过将增材制造的设计改进与合适的高温材料相结合,可以提高燃气轮机和其他应用的性能和效率。不幸的是,现有的材料要么没有足够的高温性能,要么与高质量的印刷方法不兼容。该项目将开发用于高温燃气轮机部件的新型镍高温合金复合增材制造材料。该项目的成功完成将带来更高效的涡轮机,以降低能源成本、运输成本和碳排放。预计制造业、发电业、航空航天业将受到影响。此外,历史已经证明,新的材料和制造技术往往会带来更多意想不到的创新。该项目将帮助美国引领高性能材料技术的创新,以满足价值860亿美元的燃气轮机市场的需求,并在美国增加先进制造业的就业机会。该项目将利用创新的反应性增材制造材料技术开发可3D打印的先进高温合金。在增材制造过程中,高温产物相将在高温合金基体中原位合成,以显著提高高温性能和可打印性。在NSF一期项目中,这种创新的反应性增材制造技术已被证明适用于广泛的材料系统,包括镍高温合金。与传统合金相比,使用该技术生产的金属基复合材料的强度、耐磨性和高温性能大大提高。此外,这项技术已经证明了消除合金微观和宏观开裂问题的能力,这些问题以前被认为是不可打印的。该项目旨在进一步开发一种或多种与激光粉末床熔融增材制造兼容的高温高温合金,用于燃气轮机的热段。该项目的范围包括理论和实验开发以及新材料原料,增材制造加工条件和热处理的评估。打印部件的评估将包括密度、硬度、标准和高温拉伸性能、蠕变、微观结构和相分析的测量。涡轮部件将被增材制造用于试点研究。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
