The Vickers hardness test is a versatile hardness test method, used for both macro and micro hardness testing. 3.1.3 Vickers Hardness Test The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf. Because of the wide test force range, the Vickers test can be used on almost any metallic material. The Rockwell hardness test is used for macro hardness tests, which are generally defined as tests that use indentation loads below or equal to 1 kgf. Back to Index.

The indenter is a pyramid-shaped containing angle of 136 in-between opposite faces and 1 to 120 kgf load is applied. : HV 0.01; HV 1; HV 10), the Vickers process can be subdivided into three hardness testing load ranges: in the micro, low-load and conventional (macro) hardness range. A typical Vickers hardness is specified as follows: 356HV0.5.

… The test methods include a variety of micro hardness and macro hardness testing services, such as Rockwell, Superficial Rockwell, Brinell, Vickers and Knoop testing. ... the test force and the application time. Applications. Vickers methods and applications Back to overview Depending on the magnitude of the test force according to ISO standard (and hence on the Vickers Method, e.g. The required surface condition for the Rockwell hardness test depends on the load used.

For special application like introduction in production conveyor lines and robots.

In the Vickers hardness test, the specimen is indented with a diamond indenter. Shape and impression of Diamond indentor for Vicker hardness test are given below: Vickers methods and applications Depending on the magnitude of the test force according to ISO standard (and hence on the Vickers Method, e.g.

Hardness test on camshafts, gas bottles, ball bearings, etc.. Vickers methods and applications Back to overview Depending on the magnitude of the test force according to ISO standard (and hence on the Vickers Method, e.g. The part size is only limited by the testing instrument's capacity. : HV 0.01; HV 1; HV 10), the Vickers process can be subdivided into three hardness testing load ranges: in the micro, low-load and conventional (macro) hardness range. Portable testing devices have been developed that permit in-situ hardness measurements thus offering quick and economical supplements to conventional, stationary testing machines. The latter can be omitted with the standard time of 10 to 15 seconds. It has a broad load range, and is suitable for a wide range of applications and materials.

In the Rockwell hardness test, the measure of the hardness is not an indentation surface but an indentation depth.

The Vickers hardness test has two distinct force ranges, “Microindentation Vickers” (10 - 1000g) and “Macroindentation Vickers” (1 - 100kg), to cover all testing requirements. Testing is performed to ASTM specifications, as well as other standards and customer requirements for the type of material and application. 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 - HV1000). The Vickers hardness test is suitable for soft to very hard materials and especially for thin sheets! Conventional hardness testers, like Rockwell, Brinell or Vickers machines, require the test piece be brought to the testing device; but this is not always possible. AUTOMATIC HARDNESS TESTERS Customizable hardness testers for Rockwell, Brinell, Vickers and Jominy hardness test methods. Vickers hardness machine - The testing machine shall support the test specimen and control the movement of the indenter into the specimen under a preselected test force, and should have a light optical microscope to select the desired test location and to measure the size of the indentation produced by the test. : HV 0.01; HV 1; HV 10), the Vickers process can be subdivided into three hardness testing load ranges: in the micro, low-load and conventional (macro) hardness range. Working.

Where 356 is the calculated hardness and 0.5 is the test force in kg. Before application of the Rockwell hardness test, you must prepare the surface of the material to be tested.
