Effect of milling conditions on the strength of alumina-silicon carbide nanocomposites

摘要

Processing effects of wt ball-milling on the microstructure and fracture strength of Al_2O_3/5 vol/100 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 Al_2O_3 grinding media, maintaining the homogeneity of the ball- milled powders.
