Vickers hardness — ▪ mineralogy a measure of the hardness of a material, calculated from the size of an impression produced under load by a pyramid shaped diamond indenter. Devised in the 1920s by engineers at Vickers, Ltd., in the United Kingdom, the diamond … Universalium
hardness tester — ▪ device device that indicates the hardness of a material, usually by measuring the effect on its surface of a localized penetration by a standardized rounded or pointed indenter of diamond, carbide, or hard steel. Brinell hardness is … Universalium
Hardness — This article is about mechanical properties of materials. For other uses, see Hard. Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Macroscopic hardness is generally… … Wikipedia
Indentation hardness — tests are used to determine the hardness of a material to deformation. Several such tests exist, wherein the examined material is indented until an impression is formed; these tests can be performed on a macroscopic or microscopic scale. When… … Wikipedia
Knoop hardness — ▪ mineralogy a measure of the hardness of a material, calculated by measuring the indentation produced by a diamond tip that is pressed onto the surface of a sample. The test was devised in 1939 by F. Knoop and colleagues at the National… … Universalium
Rockwell hardness — (RH ) a measure of the hardness of a metal introduced by Rockwell in 1922. In a Rockwell hardness test, a penetrator makes an indentation in the metal under two constant loads, a minor load (generally 10 kilograms) and then a major load. The… … Dictionary of units of measurement
Ceramography — is the art and science of preparation, examination and evaluation of ceramic microstructures.[1] Ceramography can be thought of as the metallography of ceramics. The microstructure is the structure level of approximately 0.1 to 100 µm, between… … Wikipedia
Rockwell scale — The Rockwell scale is a hardness scale based on the indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a… … Wikipedia
