Vickers hardness and compressive strength

Journal of the Mechanics and Physics of Solids, 1958
Abstract Hardness and compression tests are reported for a wide variety of materials. A simple empirical method for relating hardness number to the stress-strain curve is suggested. The correlation obtained leads to the conclusion that the Vickers test is not at all sensitive to yield stresses corresponding to compressive strains greater than 0.15.

Vickers Hardness Indentations Measured with Atomic Force Microscopy

Journal of Testing and Evaluation, 1998
Abstract Vickers hardness indentations on a steel gage block (-900 HV) with diagonals between 3.4 and 44 µm have been measured with a calibrated atomic force microscope (AFM) and with an opticalbased method. From the AFM images the diagonals were measured from hard copies of diagonal profiles and automatically by image analysis.

Low-Load Vickers Microindentation Hardness Testing

AM&P Technical Articles, 2012
Abstract This article reviews the measurement physics of macro and micro Vickers indentation testing and the factors that determine measurement precision and repeatability. Study results show that when force loads of less than 100 gf are used, it is difficult for operators to precisely determine the position of the indenter tip, leading ...
