Abstract
The results of a comparative analysis of three methods for calculating the elastic modulus during dynamic instrumental indentation are presented: in accordance with GOST R 56474, GOST R 8.748 and the proposed original method based on data from optical analysis of the indentation using prepared samples of alloys 20Х25Н20С2, 20Х23Н18 and BrANZhNMts9-4-4- 1.
