September 2009; accepted 30 January 2010 Abstract: The magnesium matrix composites reinforced by graphite particles and Al2O3 short fibers were fabricated by squeeze-infiltration technique. The additions..., the composites have similar worn surface. At high load, the composite with 1.0% Ce has the best wear resistance due to the existence of Al3Ce phase. The Al3Ce phase improves the thermal stability of the matrix......
