摘要：

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 degrees C. Transmission electron microscopy revealed cuboidal precipitates in the matrix. Various strengthening mechanisms originating from the matrix and the reinforcing particles are discussed.
