Magnesium alloys have high potential for applications in aerospace and vehicle manufacturing industries due to their low densities and possibility of achieving high specific strength and high stiffness. Due to low strength and relatively low stiffness of magnesium, their applications are impeded. This research focuses on a recipe of multicomponent alloys of magnesium with varied percentages of Mg, Al, Cu, Mn and Zn obtained from literature and optimizes the percentage compositions to obtain for high specific strength and specific stiffness. Relationships among percentage constituents of the alloy components are examined in Matlab R2022b using multiple linear regression. Optimization is achieved using genetic algorithm to determine the specific strengths and stiffness. The resulting optimal alloy component percentages by weight are used for microstructure simulation of thermodynamic properties, diffusion and phase transformations of proposed alloy is done in MatCalc software version 6.04. Results show potential for improved mechanical properties resulting from disordered structure in the high entropy magnesium alloy.
