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. Consequently, in a Vickers hardness test on a metal that has not fully work-hardened, σ f ≥ σ Y. The stress generated under the Vickers indenter in a work-hardening metal can be represented as .There are different scales to measure hardness, including Brinell hardness, Rockwell hardness, Meyers hardness, and Vickers hardness test. The Vickers hardness scale, named after the company where it was developed in 1921, . For metal crystalline materials, the rule of thumb is hardness/3. Based on BS EN ISO standard: BS EN ISO 6507-1 .
