Metal composites are becoming more and more widely used as the use environment and requirements continue to improve. The creation of aluminum-steel metal composites provides a good solution for the connection of aluminum and steel materials.
At present, mainly used in the ship and construction industry, there are more kinds of aluminum-steel metal composites, such as aluminum/steel and aluminum alloy/aluminum/steel. Due to the differences in properties such as melting point and strength between metals, many intermetallic compounds can be generated between two metals, and it is not easy to combine two metals or three metals at will to make composite materials to meet the requirements of use.
Different metals in the explosion welding process form a molten layer and molten blocks and other hard brittle intermetallic compounds that affect the strength of the intermetallic bond, after subsequent thermal processing or heat treatment, intermetallic compounds will slowly generate and grow, which will seriously weaken the strength of the bimetallic bond. As ships are getting larger and larger, the application temperature and bond strength requirements are getting higher and higher. In order to improve the bonding strength of the bonding interface of the aluminum-steel transition joint, one or more metals are often chosen to be inserted as an intermediate layer in the aluminum-steel.
Aluminum steel composite plate bond strength improvement of the key point for the transition layer metal material selection. The most basic principle of choosing the transition layer is that the transition layer can not produce brittle intermetallic compounds with both sides of the metal or can be a completely solid solution.
