Abstract

A device and method are described for measuring and evaluating mechanical properties such as microhardness of a material. The present invention conveniently incorporates commercially available hardness testing equipment but modifies it to permit continuous evaluation and measurement of the displacement of the stylus used to indent the sample being tested. By simultaneously monitoring displacement, load applied to the stylus and time values relating to the mechanical properties of the material such as wear, fatigue and tensile strength are obtained.
