Short carbon fiber reinforced Mg matrix composites (Csf/Mg) were prepared by an infiltration–extrusion integrated technique in which pressure infiltration and liquid–solid extrusion are performed continuously. Their compressive properties were evaluated in the temperature range 20–300°C, and compared with Csf/Mg composites fabricated by only pressure infiltration technique. The results show that after liquid–solid extrusion, the fiber tended to align along the extrusion direction, and a refined-grain microstructure was obtained, thereby contributing to a significant increase in both compressive strength and yield strength up to 200°C, but they are abnormally lower than those of the infiltrated composite at 300°C due to fiber rotation and a different deformation mechanism related to the finer grain structures.
