Microhardness of aged NiO single crystal

Deformation of MgO by Vickers microindentation tests

“…For NiO, our values agree well with those of [3]. They are slightly larger than those of [8] (Table I ) and lower than those of [5].…”

“…2014 La microdureté Vickers a été mesurée à température ordinaire dans des faces (100), (110) et (111) de MgO, en faisant tourner la diagonale de la pyramide. Les [3]. This shows that hardness values Hv can be related to dislocation mobility.…”
