摘要：

alpha-Al(2)O(3)micropowder with the even coating of Y2O3 Was obtained in such an experiment by using alpha-Al2O3 powder as base material and Y(NO3)(3) solution as coating phase through the liquid phase coating method. The aluminium matrix composite reinforced by alpha-Al2O3 particles modified by Y2O3 was fabricated. The microstructure of the composite is more even. The mechanical properties testing indicates that the strengthening effect of the modified-Al2O3 porticles on the Al alloy is improved obviously and the tensile strength of the composites increases by 27.2%, yield strength increases by 33.1%, and the elongation increases by 10.3%.
