Abstract
Silver powder in developing sintered YBa2Cu3O7−x (YBCO)-metal composites since applications require further improvement in mechanical properties of the bulk superconducting material. In this study the volume ratio of silver (Ag) powder-to-YBCO was varied up to 38%. Monolithic and composite beam specimens were manufactured by uniaxial compaction. Effect of Ag powder on the sintered density of the composite has been quantified using a nonlinear relationship. Stress-strain-critical current properties of bulk YBCO/Ag composites were investigated in three-point bending at 77 K. Addition of Ag powder resulted in a greater volume change after sintering and also showed higher strength compared to the monolithic. Improvements in strength resulting from Ag addition are compared to several other published data. Effect of Ag powder addition on volume change and strength of the bulk superconducting material has been quantified.
