Effect of Strain Rate on the Deformation Characteristic of AlN Ceramics under Scratching

Effect of Strain Rate on the Deformation Characteristic of AlN Ceramics under Scratching

To clarify the influence mechanism of strain rate effect on deformation characteristics of aluminum nitride (AlN) ceramics, some varied-velocity nanoscratching tests were carried out using a Berkovich indenter in this paper. The deformation characteristics of the scratched grooves were observed usin...
