这个小型企业创新研究二期项目将开发高质量的制造程序，以经济高效地生产高性能氧化分散强化银（ODS-Ag）护套高温超导体（HTS）电线。我们已经在第一阶段的研究中成功证明，利用稀银合金前驱体的内部氧化制备的新型ODS-Ag材料是一种可行的用于高温超导导线的先进护套材料，可以提高所得复合材料的机械和电气性能。利用全面质量管理（TQM）原则，我们将在第一阶段成果的基础上，开发与稀银合金的鉴定和加工相关的质量制造程序。在我们的方法中，我们将解决与原材料采购、加工和质量保证相关的潜在技术和经济因素。我们二期项目的成功将导致稀释银合金鉴定程序的优化，以提高高性能ODS-Ag护套高温超导线的质量，最终导致产品的性价比逐步提高。成功开发具有成本效益的ODS-Ag护套高温超导线将大大加速并广泛实现高温超导的批量应用。改进后的电线强度和坚固性的提高将有利于电力传输电缆、电动机和发电机等机械要求苛刻的应用。同样，改进导线的交流性能将有利于变压器、电感器和故障限流器等用电要求高的应用。

DMI-9527558 Riley This Small Business Innovation Research Phase II project will result in the development of quality manufacturing procedures for the cost-effective production of high-performance Oxide Dispersion Strengthened Silver (ODS-Ag) sheathed High-Temperature Superconductor (HTS) wire. We have demonstrated in our successful Phase I Research that novel ODS-Ag materials fabricated using internal oxidation of a dilute Ag-alloy precursor are viable advanced sheathing materials for HTS wire that will enhance the mechanical and electrical properties of the resulting composite. Using Total Quality Management (TQM) principles, we will build on our Phase I achievements and develop quality manufacturing procedures associated with the qualification and processing of dilute Ag-alloys. In our approach, we will address the underlying technical and economic factors associated with raw material procurement, processing, and quality assurance. Success in our Phase II program will result in dilute Ag-alloy qualification procedures optimized for the quality manufacture of high-performance ODS-Ag sheathed HTS wire, ultimately leading to a product with an incrementally improved price to performance ratio. The successful development of cost-effective ODS-Ag sheathed HTS wire will significantly accelerate and broadly enable a multiplicity of HTS bulk applications. The increased strength and robustness of the improved wire will benefit such mechanically demanding applications as Power Transmission Cables, Motors, and Generators. Similarly, the improved alternating current performance of the improved wire will benefit such electrically demanding applications as Transformers, Inductors, and Fault Current Limiters.
