Silver-sheathed YBa{sub 2}Cu{sub 3}O{sub x} (YBCO) powder was thermomechanically processed by rolling wire into flat tapes from sealed 6.3 mm diameter, 76 mm long billets. Transport J{sub c} values at 77 K in zero applied magnetic filed reached about 600 A/cm{sup 2}. Mechanical processing of powder-in-tube specimens involves fracture, densification, and sliding of powder particles as well as deformation and work hardening of the metallic sheath. A model of these effects has been developed and the experimental results suggest that the deformation properties of the powder dominate the stresses to fabricate the tapes. 10 refs., 6 figs.
