In the traditional hot forging, the temperature of the billet is heated to the forming range, and the die does not need to be heated or only slightly preheated. In isothermal forging, the temperature of the die needs to be heated to the same as that of the billet and kept constant during forging. This paper proposes a new method, which is to contro...
