Strengthening in a WE54 magnesium alloy containing SiC particles

The microstructure and the mechanical properties of the WE54 magnesium alloy reinforced by 13 vol.% of silicon carbide particulates were studied. The composite material was prepared using a powder-metallurgical technique. Compressive deformation properties of the composite were investigated in the temperature range from room temperature up to 300 °C. Transmission electron microscopy revealed cuboidal precipitates in the matrix. Various strengthening mechanisms originating from the matrix and the reinforcing particles are discussed.
