Analysis of Indentation Size Effect of Vickers Hardness Tests of Steels
Advanced Materials Research, 2013In this work, the indentation size effect (ISE) in Vickers hardness tests of steel with selected heat treatments (annealed or tempered) has been investigated and analysed. Systematical hardness tests were performed within a commonly used micro-load range.

The evaluation of the structure and hardness of processed plastics by the Vickers microhardness test
Colloid and Polymer Science, 1977The Vickers microhardness test has been used as an additional tool for the determination of the microstructure of an injection moulded semicrystalline thermoplastic. The results show for the first time that there is a clear and well defined correlation between microhardness measurements and changes in preferred orientation through the thickness of the ...

Robust algorithm for automated microindentation measurement in Vickers hardness testing
Journal of Electronic Imaging, 2012Current algorithms for automated processing of Vickers hardness testing images are unsuitable for a broad range of images that are taken in industrial environments because such images show great variations in the Vickers indentation as well as in the specimen surface.

AbstractThe evaluation of the elastic-plastic properties of a material by using an ultra-low load hardness test requires a geometrical calibration that must take into account the imperfect form of the diamond indenter. In the present work, the Vickers indenter offset of the microindentation equipment was estimated using differently heat-treated steel ...

Examination of the indentation size effect in low-load vickers hardness testing of ceramics
Journal of the European Ceramic Society, 1999Abstract The indentation size effect (ISE) in Vickers hardness for several ceramic materials was observed in a relatively wider range of applied test load. It was shown that the proportional specimen resistance (PSR) model proposed by Li and Bradt is insufficient for describing the experimental data. By considering the effect of the machining-induced
