AbstractAl2O3/Al nano-powders prepared by plasma evaporation method were compacted at room temperature into disc-shape samples with a dimension of dia. 25 mm x 2 mm. The samples were sintered at 620 degreesC for 40 min and then cold-rolled, a high relative density of 99% was achieved. The results of tensile test on the Al2O3/Al nano-composite show a high yield strength Of sigma(0.2) and a high breaking strength of sigma(b), which are 12-16 times and 5-6 times that of annealed coarse-grained Al, respectively. The microstructure and thermal stability of the composite were studied. The effects of nanocrystalline matrix, the content of amorphous Al2O3, and cold deformation on the mechanical properties of the composite were discussed.
