PAGE 4 Vickers Hardness Test The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a pyramid with a square base and an angle of 136 degrees between .Objective: The Vickers hardness test mainly serves to measure the hardness of materials, its physical durability. Hardness is defined as a material's “resistance to deformation” (#1) and it can vary depending on the material. For example, .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 Vickers hardness test method, also referred to as a microhardness test method, is mostly used for small parts, thin sections, or case depth work. The Microhardness test procedure, ASTM E-384, specifies a range of light loads using a diamond indenter to make an indentation.

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 .Hardness test methods in the macro range include Brinell, Vickers and Rockwell. Hardness testing in the low-load range applies when the test load falls between an interval of 0.2 kgf and 5 kgf (test load ≥ 0.2 kgf and < 5 kgf). The most commonly used low-load method is Vickers. Low-load hardness testing is mainly used for testing of small . Hardness of the samples has been evaluated by using Vickers Hardness Test. The Corrosion behaviour of as-received and thermally oxidised samples have been evaluated by using weight loss method.See 5.10 for the proper reporting of the hardness level from measurements of area or depth of the indentation made by and scale. forcing a specified indenter into the surface of a material under as-found condition, n— specified static loading conditions. 3.2.5 the state of the hardness ma- chine as reflected by the initial verification .
In Vickers hardness testing, a square pyramidal diamond indenter with specified face angles is used (see figure below). After the pyramidal diamond tip (indenter) is pressed into the test sample at a perdetermined load (F[N]), the indentation on the sample is measured using a microscope.
