Abstract : The emphasis of this exploration was to examine the workability and work hardening performance of Mg (Magnesium) specimen and Mg-B4C composites created via the powder metallurgy technique. The pure Mg and Mg-B4C composites are made with distinct weight percentages (Mg-5% B4C, Mg-10% B4C, and Mg-15% B4C) at the unit aspect ratio. The powders and composites characterization are executed by SEM (Scanning Electron Microscope), EDS (Energy Dispersive Spectrum) with an elemental map, and XRD (X-ray Diffraction) examination. It displays that, the B4C particles were dispersed consistently with the Mg matrix. The workability and work hardening examination was conducted in triaxial stress conditions using the cold deformation process. The consequence of workability stress exponent factor (βσ), distinct stress proportion factors (σm/σeff and σθ/σeff), instantaneous work hardening exponent (ni), work hardening exponent (n), coefficient of strength (k) and instantaneous coefficient of strength (ki) are recognized. The outcome displays that Mg-15% B4C specimen has greater workability and work hardening parameter, initial relative density, and triaxial stresses compared with the Mg specimen and Mg-(5–10%) B4C composites.
