The Vickers hardness test method can be also used as a microhardness test method , which is mostly used for small parts, thin sections, or case depth work.
W. Kollenberg, in Concise Encyclopedia of Advanced Ceramic Materials, 1991. 1.1 Vickers Hardness. The Vickers test employs a square-based pyramid with an angle of 136° between opposing faces. The Vickers hardness is defined as the applied load P divided by the surface area of the impression.The relationship between the two scales depends on the material and its hardness range. Here’s a simplified process for converting Vickers hardness (HV) to Rockwell hardness (HR): 1. Obtain the Vickers Hardness Value (HV): Conduct a Vickers hardness test on the material using the appropriate indenter and load for your material. 2.

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 method is descibed along with links to useful tables and charts 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.E 140 Hardness Conversion Tables for Metals (Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Rockwell Superficial Hardness, Knoop Hard-ness, and Scleroscope Hardness)3 E 384 Test Method for Microindentation Hardness of Ma-terials3 3.

Since the .Metallic materials — Vickers hardness test — Part 4: Tables of hardness values 1 Scope This part of ISO 6507 gives tables of Vickers hardness for use in tests made on flat surfaces. 2 Tables of Vickers hardness values for use in tests made on flat surfaces See Table 1 for range < HV 0,2. See Table 2 for range HV 0,2 to HV 3.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 .
Vickers hardness testing is carried out to standards such as ASTM E384 or ISO 6507 which has four parts describing the test itself, calibration and hardness tables. .

Vickers Hardness Test. The Vickers test uses a diamond pyramid-shaped indenter that presses into the material under a specific load. The Vickers hardness value (HV) is determined by measuring the diagonal of the resulting indentation.
Vickers Hardness Test. It is the standard method for measuring the hardness of metals, particularly those with extremely hard surfaces: the surface is subjected to a standard pressure for a standard length of time by means of a pyramid-shaped diamond. . The minerals contained in the scale are shown in the Table; also shown are other materials .The Vickers hardness test is a widely used standard test method for measuring the hardness of metals. It measures the ability of a material to withstand penetration by an indenter when it is pressed with a fixed load. You can also use it to measure the indentation hardness of non-metallic materials, provided they are sufficiently dense.An example would be material B scratches material C, but not material A. Alternatively, material A scratches material B slightly and scratches material C heavily. Relative hardness of minerals can be assessed by reference to the Moh’s Scale that ranks the ability of materials to resist scratching by another material.

The Vickers hardness test is specified in this document for lengths of indentation diagonals between 0,020 mm and 1,400 mm.
The most commonly used low-load method is Vickers. Low-load hardness testing is mainly used for testing of small parts, thick coatings and materials with low hardness. Small test loads < 0.2 kgf that create small indents on the test pieces are used for micro hardness tests (most commonly used method: Vickers). Therefore, hardness tests in the .I. Significance of Vickers Hardness Standard Test. Vickers hardness test is the nondestructive testing method, which is significant while evaluating materials, a quality check of the manufacturing procedure, and creating new products.
