The study was carried out as part of the development of a non-destructive method for measuring the mechanical properties of metals and alloys based on the dynamic instrumented indentation method. The purpose of this work is to study the possibility of measuring the modulus of elasticity using a modified Leeb hardness tester. The experiment was carried out on samples of 20X25H20C2, 20X23H18, BpA9Zh4H4Mts1 alloys.
