Information × Registration Number 0206U005626, 0103U008380 , R & D reports Title The influence of high pressure-high temperature treatment on microstructure of RBCO ceramics (R=Y, Nd) and study of relationship between the microstructure, superconductive and mechanical properties popup.stage_title Head Prikhna Tatiana, Registration Date 12-04-2006 Organization V.Bakul Institute for Superhard Materials popup.description2 The MT-YBCO samples oxygenated under controlled oxygen pressure exhibited at 77 K the critical current density jc=85 kA/cm2 in zero field and more than 10 kA/cm2 up to 5 T field (when the external magnetic field was perpendicular to the ab-plane of Y123); the jc=23 kA/cm2 in zero field and jc close to 1 kA/cm2 in 10 T field (when magnetic field was perpendicular to the c-axis of Y123). The microstructure of these samples contained an unusually high density of twins (about 30 twins per 1 mm) as well as a lot of stacking faults around Y211 inclusions. High pressure - high temperature treatment causes an increase in the material density (up to near theoretical one), microhardness and fracture toughness.
