ZL202 matrix composite reinforced by Al2 Os particles was prepared by combining in-situ reaction and casting techniques. Particles' size in the composites was from 1 to 5microns in diameter. X-ray diffraction analysis verified that the reinforcing particleswere δ-Al2 O3 which belong to γ-Al2Oa series. The wetting angle between matrix andreinforcement was less than 90°. Energy spectrum analysis indicated that the reactionin bell cover pressing process took place not so completely as in flouring stir process.When the reaction was finished, the matrix was still ZL202 alloy in both processes.
