ANALYSIS Hardness Value: A measurement of the material's hardness is provided by the test's Vickers hardness number. Greater hardness is indicated by a higher HV. Vickers hardness values are a useful tool for comparing the hardness of various materials .Micro Vickers Hardness Tester Vickers Hardness Test of Curved Surfaces Vickers hardness is used as an index of the mechanical and physical properties of materials in a variety of fields, including quality control at production sites, research and development, and analysis. A distinctive feature of the Vickers hardness test is its simplicity.
the hardness value is calculated based on the applied load and the indentation size. Vickers belongs to the optical methods. Vickers Hardness The Knoop hardness test is similar to the Vickers test but uses a rhombic-based diamond indenter instead of a pyr-amid. It is commonly used for measuring the hardness of thin
Vickers and Knoop hardness values are not designated by a number alone because it is necessary to indicate which force has been employed in making the test. The hardness numbers shall be followed by the symbol HV for Vickers hardness, or HK for Knoop hardness, and be supplemented by a value representing the test force in kgf. Examples: 450 HV .

The Vickers Hardness test (ISO 6507) is used to characterize hardness of various solid materials (metals, ceramics, etc.). A diamond pyramid is pressed against the solid with a certain normal load and the hardness is calculated based on the imprint left on the surface.Metallic materials — Vickers hardness test — Part 4: Tables of hardness values 1 Scope This document gives tables of Vickers hardness for use in tests carried out in accordance with ISO 6507-1. 2 Normative references The following documents are referred to in the text in such a way that some or all of their contenthigher. At lower test loads the Vickers hardness may be load-dependent. In Table 2 are given the Vickers hardness numbers for a test load of 1 kgf. For obtaining hardness numbers when other test loads are used, the Vickers hardness number obtained from Table 2 is multiplied by the test load in kilograms-force (Table 3). N. ote 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.
