Low Load Vickers Hardness Measurement
During Vickers Hardness inevitable user errors are introduced during the measurement of the imprint under the microscope. Especially at low loads, small measurement errors of the indent size will produce large hardness deviations. In comparison, nanoindentation testing evaluates the mechanical properties of a material by driving the indenter tip into the test material and precisely recording the evolution of load and displacement of the tip. It avoids user errors in imprint size measurement.
