Properties of joint in the bimetallic rods Cu-Al and Cu-steel after explosive cladding and the process of rolling
In the paper the microhardness, the microstructure and the bond strength of interface of bimetallic joint on the cross sections of the test bar have been investigated. For the experimental analysis, a bimetallic bar was manufactured using an explosive technique method and the process of rolling. For tests, 23 sets of specimens were prepared each consisting of copper tubes (grade M1-E), rolled steel rods (grade St3S), drawn rods (grade 55) and aluminium rods (grade PA6). The copper tubes and the steel and alumininum rods had different diameters, owing to which different distances between the rods and the internal tube walls were obtained. The results of the research show a significant deviation in microhardness distribution in the both layers near the joining border.
