Step-by-step insights provide engineers and laboratory professionals with essential techniques in metallography, from ...

Modern techniques for measuring hardness invariably involve subjecting a material to relatively high pressures in a localized area, using an indenter that is harder than the substance under test. For ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

This class presents a description of each hardness testing method, along with discussions on how to choose and perform a test, how to read hardness ratings, and how to prevent common errors. Hardness ...

• Engineers can use hardness testing to verify the composition or heat-treatment history of materials. • Rockwell, Brinell, Vickers, and Shore are common hardness tests. Their use depends on the ...

A spray-applied nanocomposite coating kills over 99.99% of bacteria on touchscreens while resisting scratches, combining ...

Unique portable device for the performance of standardized, static ball penetration tests according to Brinell up to a max. load of 29420 N. It is possible to carry out hardness tests on materials and ...
