Abstract Scope |
Magnesium alloys are rapidly emerging as the lightest structural material, potentially used in electronics, automobile, aerospace, and biomedical applications. The Mg-4Zn-4Gd (ZV44) alloy has been processed through hybrid severe plastic deformation techniques, which has shown impressive improvements in tensile (180%), hardness (135%), fatigue (85%), and fracture properties (70%) compared to the solution treated specimen. Such improvements were due to the hybridization of more than one plastic deformation technique, unlike single SPD techniques such as rolling or ECAP. The optimization of repetitive-hot-rolling and uniaxial-forging has modified and produced bimodal microstructure resulting in good strength and ductility. The processing- microstructure-property correlation was done exhaustively with the help of HR/S-TEM, FE-SEM/EDS, and XRD. The reasons for characteristic enhancements are grain refinement, dislocation density, strain hardening, fragmentation and distribution of precipitate, etc. |
