description: This work is devoted to the study of bimetals obtained by explosion welding. Before the study, samples were cut from the welded joints. For the study, we took steel-aluminum alloys (4 samples) and steel-titanium (2 samples). Then, microsections were made on the surface of each of the samples. After that, they were subjected to chemical etching and used the method of optical and electron microscopy. In Figures 21-23, 28, 33, the microstructures of these samples were presented. They were obtained by metallographic studies using an optical microscope. A local chemical analysis of samples 4-6 was carried out to determine the composition of the structure of inclusions at the boundary of metal compounds and to determine the composition of the structure of inclusions in the transition layer (gray) at the boundary of metal compounds. The presence of defects in the form of discontinuities was not found, all connections are made with high quality. On samples No. 5 and No. 6 inclusions of titanium intermetallic compounds were found, the composition of which depends on the alloyed metals among themselves. The effect of detonation on the metal structure (sample no. 4 and sample no. 17) was also evaluated, namely at the initial and final points of detonation. According to these samples, it can be concluded that their microstructures are similar. The differences are in the size and length of the wave. For sample No. 4, the wave is shallower, due to its proximity to the detonation point, Figure 37. Sample No. 17 has a longer wave, due to the fact that it is located farther from the detonation point, Figure 38. Steel 09G2S and titanium alloy B265 Gr5 have a characteristic microstructure. Titanium alloy has a two-phase lamellar structure (Figures 37, 38 a), and steel has a ferrite-pearlite structure (Figures 37, 38 b). When these metals are combined, their structure is strongly deformed. Banding is formed, which pulls the metal structures along their fusion. Structural bedding is more pronounced in titanium due to high deformation in this part of the sample. No defects in the form of discontinuities were found at the junction.
