Composite materials have many applications in industries and using these composites in deep drawing process is a new trend to obtain high quality drawn products. This study aims to prepare the hybrid Metal Matrix Composites (MMC's) iron-based reinforced with 0, 1, 2, 3 and 4% volume fraction of constant mix (80% Al2O3 and 20% ZrO2) by means of powder metallurgy and investigate the mechanical properties of these hybrid Composites. The powders were compacted at 640 MPa and sintered at 1120 °C in the presence of argon gas. The purity, density, average grain size and shape were measured by Dosimeter, particle size analyzer and SEM. The best mechanical properties were obtained at (97% Fe + 3% (80% Al2O3 + 20% ZrO2) among all reinforcement volume fractions and the composites has properties of 61%, 37% and 7% more than the matrix properties for compression strength, hardness HRC and radial crushing strength respectively. •In this work, the metal matrix composites based on the iron are prepared and several mechanical tests such as crash, compression, tensile and hardness tests in addition SEM Microstructure is used to measure the mechanical and physical properties of the metal matrix composites.•The best mechanical properties is obtained at (3%)volume fraction of reinforcement among all reinforcement volume fractions and MMC's has (61%), (37%) and (7%) more properties than the matrix properties for compression strength, hardness HRC and radial crushing strength respectively.•SEM proved that there is three phases of FeAl2O4 and FeZrO2 in addition to Fe, Al2O3 and ZrO2 as pure materials.
