The indenter is the same for both ranges; therefore Vickers hardness values are continuous over the total range of hardness for met- als (typically HV100 .The Vickers hardness test uses a Vickers indenter, which is shaped like a squat pyramid and is typically pressed into the surface of the material for 10 seconds. The amount of force used is of a pre-determined amount and varies depending on the materials being tested. . That said, careful sample preparation is necessary to ensure that the .

A standardized test procedure used to determine the hardenability of steel, the Jominy test (End Quench Test) can be performed using either the Vickers or Rockwell hardness test method. When selecting which to use, you should consider relevant standards, as well as the usual criteria when choosing between different types of hardness test.The Vickers hardness test was developed by George E. Sandland and Robert L. Smith at Vickers Ltd. in the year 1921, as an alternative to the Brinell method to determine the hardness of materials. This Vickers hardness test is usually easier to use compared to other hardness tests. . Additionally, sample preparation is crucial to achieving a . The Vickers Hardness number (HV) is then calculated by dividing the applied load (in kgf) by the surface area of the indentation (in square millimeters).
