Abstract:When Cr, Mo and Ti were added to Fe-Al/Al₂O₃ composite, the bending strength and fracture toughness of the composite were increased sharply. The highest value of bending strength can exceed 600MPa and the average value of fracture toughness exceed 12MPa·m^1/2. With increasing content of Mo and Ti, the bending strength and fracture toughness both express the trend of increasing first and then decreasing. When the alloying elements were added to the composites the alloying extent is improved. The fracture mode of the composites are mainly transcrystalline.
