The Vickers hardness test is a macro and microhardness testing method, while the Rockwell test is used only as a macro testing method. The Rockwell test is a quick and direct process, while the Vickers hardness test is a slow process and requires other optical devices such as a microscope to measure the hardness of the object.The Vickers hardness test is often regarded as easier to use than other hardness tests: The process can be performed on a universal or micro hardness tester; the required calculations are independent of the size of the indenter; and the same indenter (a pyramidal diamond) can be used for all materials, irrespective of hardness. . The hardness of steel depends on several factors, such as its composition, manufacturing, and heat-treating processes.The different hardness scales use different loads, different indentor shapes, and different measurements to obtain the hardness number. There are no straightforward formulae to establish relationships between the different scales, making .A Vickers hardness tester. 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. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter .

PRINCIPLE OF THE VICKERS HARDNESS TEST: The test consists of punching into the piece to be tested, using a determined force, a pyramid shaped indenter with a square base, having an angle of 136° to the summit and in measuring the diagonal (d) of the indent left in the piece, after having removed the load. The Vickers hardness is the quotient .

The Vickers hardness test measures material hardness by determining the size of an indentation made by a diamond pyramid-shaped .Hardness test methods. Common tests for hardness in metals involve measuring the resistance to indentation by a hardened steel or diamond ball, cone or pyramid. The common test methods include: – Brinell. Vickers. Rockwell. The hardness figures do not have units.Hardness tests measure the resistance of a material against plastic deformation.To perform these tests (be it Brinell, Rockwell, or Vickers), an indenter is pressed on the surface of the specimen with a specific force F F F .
Hardness testing according to current standards. Our hardness testing machines support a wide load range for the Vickers, Brinell and Knoop test methods.
