摘要：

Dense, bulk Bi2Sr2CaCu2Ox bars were fabricated by sinter forging. The bars exhibited strong textures in which the c axes of the platelike grains were preferentially aligned parallel to the pressing direction. Fracture strength was measured in four-point bending, and in compression at angles of 0, 45, and 90-degrees to the pressing direction. Maximum strength in tension was 100 MPa and average strength was 84 MPa. Maximum strength in compression, which depended on orientation, was 180 MPa and maximum average strength was 120-135 MPa.
