Vicker's Hardness of glass

Journal of Non-Crystalline Solids, 1974
Abstract An equation has been derived for the direct calculation of Vicker's hardness number of glasses from their chemical compositions. The method is based on a consideration of deformation during indentation, which was related to Young's modulus and the average single bond strength of a glass.

Conversion between Vickers hardness and nanohardness by correcting projected area with sink-in and pile-up effects

, 2020
The Vickers hardness test has been widely used for neutron-irradiated materials while nanoindentation for ion-irradiated materials. Comparing the Vickers hardness and nanohardness of the same materials quantitatively and establishing a correlation ...

Hardness measured with traditional Vickers and Martens hardness methods

Dental Materials, 2007
To determine the differences, if any, between hardness measured with traditional Vickers and Martens hardness test methods on denture teeth under 2, 10 and 50 N loads.Hardness of acrylic resin (VIV), composite resin (ORT) and porcelain (POR) denture tooth materials was measured using a traditional Vickers hardness (HV) method and Martens hardness (HM ...

Vickers hardness concept in the light of Vickers impression

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1974
Abstract Although Vicker's hardness equation is defined with reference to the total inclined area of the permanent impression, in reality, only the diagonals are measured for calculating hardness irrespective of the morphology of the impression. The occurrence of the diagonal in the Vicker's hardness equation (Hv=2W/d2.
