Structural changes in carbon steels during explosive welding
The analysis of fine structural changes occurring in the surface layers of dynamically interacting pieces of carbon steels of different chemical composition is conducted. Transformations occurring in ferrite and pearlite are investigated using transmission electron analysis. Based on the results of mathematical modeling, the distribution of temperature fields in dynamically interacting steel billets is established. It is found that the results of numerical modeling correlate with the experimental data. To determine the degree of hardening of the material of the welded plates hardness measurement was conducted using a Vickers microhardness tester.
