When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...

• 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 ...

While hardness testing does not provide a direct assessment of product or raw material performance qualities, hardness correlates directly to qualities like strength and wear resistance. Hardness ...

The condition and physical properties of the work material have a direct influence on the machinability of a work material. The various conditions and characteristics described as "condition of work ...

THE hardness of metals, as Dr. Hugh O'Neill once said, like the storminess of seas, is easily appreciated but not readily measured. Prof. Lea has attempted to describe the various methods of measuring ...
