On the representative strain in Vickers hardness testing of 7010 aluminum alloy

Materials Science and Engineering: A, 2015
Abstract A review of the concept of representative strain in Vickers hardness testing is provided and different values reported in the literature are summarized. A new criterion for the proper selection of the representative strain is introduced. By using this criterion, the stress–strain curves of 63 specimens excised from a 7010 aluminum alloy ...

Determination of the hardness and elastic modulus from continuous vickers indentation testing [PDF]

Journal of Materials Science, 1996
Continuous Vickers (Hv) indentation tests were performed on different materials (ion crystals, metals, ceramics, silica glass and plastic). Load-indentation depth curves were taken during the loading as well as during the unloading period by a computer controlled hydraulic mechanical testing machine (MTS 810).

Vickers hardness testing of sucrose single crystals

Journal of Crystal Growth, 1994
Abstract 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
