II. APPARATUS:Rockwell Hardness testing machine, Test specimen. III. THEORY:HARDNESS- It is defined as the resistance of a metal to plastic deformation against Indentation, scratching, abrasion of cutting. The hardness of a material by this Rockwell hardness test method is measured by the depth of Penetration of the indenter.
Vickers and Rockwell hardness test, the results are given to students in the class lab by the Qness hardness test machine in Fig. 4. Different materials specimens will be tested in this laboratory experiment namely:aluminum alloy, carbon steel, brass, commercial pure copper, brass, and stainless steel etc. Figure 4. Hardness Testing Lab - Applied Technical ServicesThe smaller the indentation, the harder the material. Within the ATS hardness testing lab, hardness values are obtained by measuring the depth or the area of the indentation using one of several different test methods. They include the microhardness techniques (Vickers and

This testing is especially useful for alloy steels and irons or where testing for near surface hardness is needed. Unlike the Vickers test where the indentation length on the vertical and horizontal axes are measured and averaged, the Knoop method only uses the long axis. This measurement is then converted to a Knoop hardness number using a chart. Portland, OR IMR TEST LABSPortland, OR.
