| description | Ni-Co-W alloy is expected to be a potential material for applications in national defense, military industry and petroleum exploration. Texture has a significant influence on alloy properties. In the present work, a 44Ni-37W-19Co alloy was prepared by vacuum melting and annealed at 1200 °C for 1h after forging, baring and hot stamping. The microstructure and texture at different positions were analyzed by optical micrographs (OM), scanning electron microscopy (SEM), x-ray diffraction (XRD) and electron backscattering diffraction (EBSD) technique. The alloy presents equiaxial grains with an average size of ~90 μ m and a nearly random texture. All the average pole intensity levels at surface, sub-surface and center are ~2. The anisotropy degree along the circumferential direction is less than that along the normal direction. The maximum and minimum differences of the radial pole intensity are 0.44 and 0.04, respectively. It is expected that this work will contribute to the controllable effects of microstructure and texture to improve the properties of hot-stamped high-density Ni-Co-W alloys. |
