Hardness Testing is applied to a great number of materials, and for over 250 years, it has been an invaluable and frequently used mechanical test. A variety of hardness tests can be used to establish ...

Decarburization refers to a loss of carbon from a metal surface, particularly cast irons and steels, and occurs due to heating in a medium, which in turn reacts with the carbon atoms. Case hardening ...

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 ...

This film discusses hardness testing methods in engineering, specifically focusing on the Brunell and Rockwell hardness tests. It explains how hardness is measured through indentation and penetration ...

Knowing the type of aggregate in the concrete or asphalt to be cut influences the performance and selection of diamond blades and drill bits. Aggregate, the stone, gravel and sand used in concrete and ...
