In this study, the steel particles were used as reinforcement of the magnesium matrix. For the fabrication of the magnesium-steel particle composite, the steel particles preforms were made in different sizes with sintered at 1000-1200 ℃ and without sintered. These preforms were preheated at 750 °C and then infiltration by melt magnesium with the squeeze casting method. The microstructure of the preforms and the composites were investigated by SEM and optical microscope. Microhardness and compression tests were performed to investigate the mechanical behavior of the composites. The microstructure study showed the rigid connectivity between steel particles in the interpenetrating phases composites. Also, hardness and compression test results showed higher hardness (61 VHN) and strength (218 MPa) for the composites with 1mm steel particle size sintered at 1200 ℃. Hence, the composites with 3D-dimensionally, interconnected steel particles show significant changes in their mechanical properties.
