The strength of Al2O3/SiC nanocomposites after grinding and annealing

Abstract:

Alumina matrix nanocomposites containing about 5 vol.% SiC of < 100 nm mean particle size show a substantial increase in strength after machining and annealing. The final strength is controlled by the annealing process and achieves the same level after a coarse machining using 150-grit diamond as is achieved using a complex lapping and polishing sequence. In all cases the final anneal leads to an increase in strength. The nanocomposite retains a significantly higher residual surface-compre...
