摘要：

Very dense Bi2Sr2CaCu2Ox bulk specimens were fabricated by hot isostatic pressing or sinter forging. The specimens exhibited textures in which the c-axes were aligned preferentially perpendicular to the top and bottom faces. Fracture toughness was found to be dependent on orientation, with the values ranging from 2.7 to 3.9 MPa m0.5. The average Vickers hardness for the specimens was almost-equal-to 700 MPa. Elastic anisotropy determined by velocity of sound measurements was consistent with textures determined by x-ray diffraction.
