http://www.dhv.be/en/ The basic principle, as with all common measures of hardness, is to observe a material's ability to resist plastic deformation from a standard source. The Vickers test can be used for all metals and has one of the widest scales among hardness tests. The unit of hardness given by the test is known as the Vickers … See more The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than … See more It was decided that the indenter shape should be capable of producing geometrically similar impressions, irrespective of size; the impression should have well-defined … See more To convert the Vickers hardness number to SI units the hardness number in kilograms-force per square millimeter (kgf/mm ) has to be multiplied with the standard gravity See more The fin attachment pins and sleeves in the Convair 580 airliner were specified by the aircraft manufacturer to be hardened to a Vickers Hardness specification of 390HV5, the '5' meaning five kiloponds. However, on the aircraft flying Partnair Flight 394 the pins were later … See more When doing the hardness tests, the minimum distance between indentations and the distance from the indentation to the edge of the specimen must be taken into account to avoid interaction between the work-hardened regions and effects of the edge. These … See more If HV is first expressed in N/mm (MPa), or otherwise by converting from kgf/mm , then the tensile strength (in MPa) of the material can be approximated as σu ≈ HV/c , where c is a constant determined by yield strength, Poisson's ratio, work-hardening … See more • Indentation hardness • Leeb Rebound Hardness Test • Hardness comparison See more
