Vickers hardness testing of sucrose single crystals
Journal of Crystal Growth, 1994Abstract Using a technique developed by Gillespie [BSc Thesis, University of Strathclyde, June 1982], single crystals of sucrose 3–5 mm on an edge were grown isothermally from high-purity aqueous solution at relatively high supersaturation. The crystal fracture behavior was assessed using Vickers indentation hardness testing to relate to observations

Indentation Image Analysis for Vickers Hardness Testing
2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2018The paper presents a novel algorithm for detection and measurement of indentations in Vickers hardness testing images, within a specific case of applied research on material quality evaluation based on image processing. The algorithm performs image segmentation by binarization, morphological filtering, and region growing, where the binarization ...

Low-Load Vickers Microindentation Hardness Testing
AM&P Technical Articles, 2012Abstract 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 ...

Finite Element Method for Simulating the Vickers Hardness Test
Applied Mechanics and Materials, 2014The purpose of the present paper is to present a different approach to the finite element modeling of the Vickers hardness test measurement, and to establish a numerical correlation between the Young modulus of a material and its hardness. In order to realize this, calculations were based upon the tensions acquired as a result of the hollow caused in ...
