Hardness - Wikipedia
网页In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation, such as an indentation (over an area) or a scratch (linear), induced mechanically either by pressing or abrasion.
What is Hardness - Definition - Material Properties
网页What is Hardness – Definition. 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 ...

Mohs hardness | Definition, Table, Examples, & Facts
网页Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or.
What Is the Hardness of A Material? - The Engineering Choice
网页Hardness is the ability of a material to resist deformation, which is determined by a standard test where the surface resistance to indentation is measured. The most commonly used hardness tests are defined by the shape or type of …
Hardness | Elasticity, Mohs Scale, Indentation | Britannica
网页Hardness, resistance of a mineral to scratching, described relative to a standard such as the Mohs hardness scale. Hardness is an important diagnostic property in mineral identification. There is a general link between hardness and chemical composition (via crystal structure); thus, most hydrous.
Units of Hardness – Hardness Numbers - Material Properties
网页In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.
