In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching. Hardness is probably the most poorly defined material property because it may indicate resistance to scratching, resistance to abrasion, resistance to indentation or even resistance to shaping or l See more

Hardness conversion data have been determined experimentally and found to be dependent on material type and characteristics. The most reliable conversion data exist for steels, some of which are presented for Knoop, Brinell, and two Rockwell scales; the Mohs scale is also included.

Hardness testing is a quantitative test method. In metallurgical science, the hardness value of a material is directly related to the type of microstructure. Ferrite is softer while martensitic is a hard microstructure. In industries and laboratories, myriad types of hardness testing are performed to meet different sectors, code & standards

Hardness is the property of a material that enables it to resist plastic deformation, penetration, indentation, and scratching. Therefore, hardness is important from an engineering standpointbecause resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness.

Answer: hardness is a measure of a material's resistance to being scratched and is measured using various experimental techniques, including the rockwell tests, barcol test, durometer test, brinell test, mohs test, and vickers and knoop tests. Therefore, the values obtained often depend on the testing method of the knoop diamond.

The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For example, if some material is scratched by topaz but not by quartz, its hardness on the Mohs scale would fall between 7 and 8. Indentation hardness.

I will restrict my answer to common engineering materials from which useful objects could be fashioned, where hardness would be a useful attribute. This excludes metals that catch fire spontaneously in air, since it would be injudicious to make cars and airplanes out of them. Hardness is a measure of how difficult it is to indent a material

Material Hardness. Material hardness is measured using a variety of scales in research as well in industrial applications. The choice of scale depends on the level of hardness needing measured. The Mohs hardness scale is one of the more commonly recognized and was designed to measure the hardness of minerals by using one mineral to scratch another.

Hardness is a metric that measures how resistant a material is to localised plastic deformation caused by mechanical indentation or abrasion. It has important diagnostic properties in mineral identification or abrasion. There is a general bounding between hardness and chemical composition, thus most hydrous minerals like halides, carbonates, sulfates, and phosphates
