Abstract
Processing effects of wet ball‐milling on the microstructure and fracture strength of Al2O3/5 vol% SiC nanocomposites were investigated. Homogeneous microstructure and a high fracture strength of 1200 MPa could be achieved under the milling condition of relatively low wear contents of Al2O3 grinding media, maintaining the homogeneity of the ball‐milled powders. The fracture strength decreased with increasing wear content. Degradation of fracture strength was caused by abnormal grain growth related to wear particles from the Al2O3 balls.Keywords
