Мethods of static and percussion microhardness metals and alloys in Кotrechku

Abstract

Methods for determining the static and dynamic micro-hardness of metals using the new designs indenter. These indenter are four-sided pyramid with the angles between the faces of α – 90о and three-edged pyramid with its top corners at α – 105о . This geometry of an indenter reduces the value of work hardening during a measurement of hardness. Values of static and dynamic microhardness of metals and alloys, obtained by the proposed methods are more accurate than the conventional Knoop and Vickers methods. The novelty of the proposed method is confirmedby patents of Ukraine.
