Abstract: Experiments of hot pressing of the tapes were carried out. Parameters of pressure, temperature and time were determined. Deformation mechanism of hot pressing were also studied. Experimental results showed that hot pressing caused the core to become more dense and could avert the formation of cracks effectively. At 77 K and zero field, the maximum Jc value was up to 2.25×104A/cm2 under the conditions of 750℃, 200 MPa and 30 min.
