Joining of melt-textured YBCO using Tm 123 powder as a solder

Model experiments on joining of melt-textured YBa2Cu3O7-*d (MT-YBCO) using rings cut from bulk single domain give the strong proof that the critical current density through the soldered seam obtained using a Tm 123 powder as a solder is at the same level as that through the MT-YBCO (34 kA/cm2 at 77...

Description
Summary:Model experiments on joining of melt-textured YBa2Cu3O7-*d (MT-YBCO) using rings cut from bulk single domain give the strong proof that the critical current density through the soldered seam obtained using a Tm 123 powder as a solder is at the same level as that through the MT-YBCO (34 kA/cm2 at 77 K in the 0 T field) and that the proposed comparatively short soldering process allows us to obtain soldered bulk with the even higher jc (up to 2.5 T fields at 77 K) than that of the initial unbroken one. The seam structure (including the twinned one) slaved the structure of the jointed MT-YBCO.
