The present work aims to determine the characteristics of complex compression behaviour of the (Magnesium alloy) AZ 91E-Granite Powder-Fly Ash Hybrid Metal Matrix using the traditional plasticity theory. This started with the synthesis of compounds, which include reinforcement alloy elements, namely Granite Powder, fly ash particles, as well as pure AZ91(Magnesium alloy). This is achieved by means of a vortex method under the path of stir casting. The density was calculated using ruling of mixture formula as theatrically and experimentally found using Archimedes drainage method. The experimental density was decreased compare to the theoretical density, but the density is equal for composites and the base material. The fracture toughness is decreased for composites compare to the base material; this is due to the improvement of the grains by adding strengthening molecules. We knew that the coarse granular structure had a higher rigidity in fracture compared to the fine granular structural material. Two standard size samples (H / D ratio at 1 and 1.5) were made from each of the two different groups listed, with pure AZ91. The sample was tested to see if the compressive strength and deformation behavior by UTM INSTRON did not have friction conditions.
