“…Finally, these H v values can be referenced to relevant literature data. For single crystalline AlN (vapor deposited thick epitaxial layer), the Vicker’s hardness of 17.7 GPa is reported [ 60 ] with theoretical calculations pointing to possible 20 GPa [ 61 ]. Moreover, for AlN sintered with various additives, the hardness in the range 10–11 GPa is found [ 62 ].…”

“…The Vicker’s hardness values for the ternary composite nanoceramics are moderately high, ranging from 10.6 to 13.5 GPa, and can be referenced to the available data both for the individual/pure and binary sintered nitride systems studied by us and others. For pure hexagonal AlN nanoceramics, we reported H V spanning 12.4–17.4 GPa [ 13 ], while others quoted values from 17.7 [ 33 ] up to a theoretical limit of 20 GPa [ 34 ]. For cubic TiN nanoceramics, a range of 13.5–19.7 GPa was reported [ 13 ] and a few micrometer-thick layers of TiN were shown to exhibit hardness H V from 9.2 to 15.0 GPa [ 35 ].…”
