Knoop hardness in α-Si_3N_4 on the surfaces of(1100), (1120)and(0001)was investigated. Hardness values had isotropic character on all surfaces. Effective resolved shear stress(ERSS)was calculated assuming the slip systemsof(0001)<1120> {1100}<1120> {1100}<0001> {1101}<1120>and{2201}<1120>to be activated. The ERSS curve of the {1101}<1120>slip system explains Knoop hardness better than those of other slip systems. This fact supports{1101}<1120>to be the primary slip system in α-Si_3N_4 at room temperature.
