Study on the Bonding Mechanism of Copper-Low Carbon Steel for Casting Compounding Process

The casting compounding process for copper-steel composite material has broad prospects of application, but due to the lack of supporting theories (especially the bonding mechanism of copper-steel at high temperatures), it is developing slowly. In this research, copper-steel composite materials for...
