Abstract Scope |
Heterostructure materials, which are composed of physically distinct zones, surpass the capabilities of classically homogenous materials by combining the mechanical responses of coarse and fine grain structures, enhancing the strength of the material without compromising ductility. Pure cobalt is unique as it undergoes an allotropic phase transformation between its high-temperature face-centered cubic (FCC) phase and low-temperature hexagonal close-packed (HCP) phase, providing additional control over its microstructural features. The introduction of both microstructural and phase gradients in pure cobalt, along with an understanding of its textures, offers a pathway to tailor microstructures for improved mechanical properties. This study involves the mechanical deformation of pure cobalt to induce gradient structures, followed by a quantification and analysis of the resultant microstructures and texture. |
