Abstract
Methods have been developed for determining the static and shock microhardness of metals and their alloys using indentors of new structures made in the form of a tetrahedral pyramid with corners between the faces α = 900 and a triangular pyramid with corners at its apex α = 1050, which ensure the transition from elastic deformations to plastic ones at smaller values of plastic hardening. Values of static and shock microhardness of metals and their alloys obtained in the studies by the proposed methods are more accurate than the existing standard Knoop and Vickers.Their use is useful for calculating the optimal dimensions and geometry of finished parts. The novelty of the developed and proposed methods is confirmed by the patents of Ukraine.
