Generally, Alloy 7 18 DA disks are forged by means of hydraulic press. However this paper investigates the forging of Alloy 718 DA disk on hammers. The structure and mechanical properties of this DA disk are present. The final forming was carried out on the 63T-M hammer. Structure analysis showed successful results , grain size wasvery fine and especially did not have cold-die structure. Mechanical properties can all meet the requirements of Alloy 7 18 DA disks. This metal forming process is acceptable for Alloy 7 18 DA disks production.
