  • The hardness of solids IOPscience

    Nov 20, 2002· With brittle solids the high hydrostatic pressures around the deformed region are often sufficient to inhibit brittle fracture. Under these conditions both indentation and scratch hardness are essentially a measure of the plastic rather than the brittle properties of the solid. This provides a simple physical basis for the Mohs scratch hardness7KHKDUGQHVVRIVROLGV,D. TABOR Surface Physics, Cavendish Laboratory, Cambridge The hardness of solids Abstract.
