Abstract
Abstract
The mechanical properties of ceramic reinforced metal matrix composites make them highly attractive for various industrial applications. In this study, magnesium/metallurgic slag (Mg/MS) composites were fabricated using the powder metallurgy (PM) technique with varying MS content up to 15%, followed by sintering at 723K (450°C) for one hour. XRD analysis revealed the presence of magnesium, periclase and pseudowollastonite phases in the composites. Results of Vickers hardness and compressive strength tests showed that the maximum values were achieved in the composites containing 15% MS, with values of 93 HV and 382 MPa, respectively. Generally, as the MS content increased, the density of the composites also increased. The fracture surfaces of the experimental composites displayed cleavage, indicating brittle fracture.
