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 ...

Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

• 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 ...

The automotive industry requires steel with a high strength, and this need is continually being met by ongoing developments. One fruit of this research is advanced dual-phase (DP) steel. This is steel ...

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 ...

Inspection of manufactured goods has increasingly become standard practice to ensure products meet more and more demanding specifications. In some cases, this can mean that long established methods of ...
