Abstract

The strengthening of Al ₂ O ₃ -Cr ₂ O ₃ /Cr ₃ C ₂ nanocomposites has been investigated using nano-indentation technique. These composites are fabricated by metal-organic chemical vapor deposition using Cr(CO) ₆ as a precursor and Al ₂ O ₃ as the matrix followed by spark plasma sintering. The nanocomposites have a higher elastic modulus and are able to endure higher plastic deformation than monolithic alumina. The microstructures of the dislocation, transgranular, and stepwise fracture surfaces are observed. Moreover, Al ₂ O ₃ -Cr ₂ O ₃ /Cr ₃ C ₂ nanocomposites have high hardness, fracture toughness, and facture strength due to strengthening by second phase Cr ₃ C ₂ particles and the solid solution of Al ₂ O ₃ -Cr ₂ O ₃ .
