Abstract
The corrosion behavior and microstructural changes in explosively welded AA5083/AA1050/SS 321 multilayer tubes after heat treatment were studied. Heat treatment were performed in 350 and 450 °C for 6 and 8 h. Microscopic results indicated significant changes in the thickness and concentration of alloying elements in locally melting zone with heat treatment temperature. According to electrochemical tests results at samples interfaces, by increasing the temperature and time of the heat treatment process, the energy stored due to explosive welding is reduced, the difference in the concentration of aluminum related to steel in the interface layer decreases, and the corrosion rate (current density) and electrical charge transfer decrease.
