Abstract
A high martensite transformation rate can be obtained by hot forming process, and therefore parts with high strength and hardness can be achieved. At the same time, a new type of composite metal body structural parts with gradient hardness and strength along the thickness and length direction can be achieved through the special duct design and manufacturing process. The productive process is a “natural formation” by hot forming without the need for composite bonding, welding, riveting, or other connecting techniques. This process not only provides a new way to choose body material, but also conduces to the controllable design of the material’s properties.
