SBIR Phase I: Novel Deformation Processing of Bismuth-Based High Temperature Superconductor Composites

这个小型企业创新研究第一阶段项目将使用基本方法和简单的概念框架来说明材料和工艺硬化对Bi2223复合带材的超导性能和微观结构的相对和绝对重要性。商业上可行的高温超导(HTS)线材必须具有高JC性能和低成本。该项目将开发一种新的变形处理方案。如果成功，该公司将生产一种创新的变形工艺，在保持轧制成本优势的同时，提供压制的好处。该项目的成功完成将对所有高温超导导体的应用产生广泛的影响，特别是那些需要长而连续的长度和高JC性能的应用。HTS应用在发电、配电、运输、机械、储能和其他军用和商用系统中不可或缺的产品方面具有数十亿美元的市场潜力。特定的HTS系统和组件包括输电电缆、电机、发电机、故障限流器和变压器。

This Small Business Innovation Research Phase I project will illustrate the relative and absolute importance of materials and process hardening on the superconducting performance and microstructure of Bi-2223 composite tape using a fundamental approach and a simple conceptual framework. Commercially viable high-temperature superconductor (HTS) wire must have high Jc performance and low cost. This project will develop a novel deformation processing scheme. If successful, this firm will produce an innovative deformation process that provides the benefits of pressing while maintaining the cost advantages of rolling. Successful completion of this project will have broad impact on all HTS conductor applications, and especially those that require long and continuous lengths with high Jc performance. HTS applications have a multi-billion dollar market potential in products integral to electric power generation, distribution, transportation, machinery, energy storage and other uses for both military and commercial systems. Specific HTS systems and components include power transmission cables, motors, generators, fault current limiters, and transformers.
