DEVELOPMENT OF 2400 F FORGING DIE SYSTEM
Abstract
Work continued on (1) extending the upper temperature limit of the present hot die system, (2) minimizing the required forging sequences by using hot dies, and (3) evaluating new materials for use as a 2400 F forging die. The ultimate objective is a creation of a true hot working technology for refractory metals. The hot die system was installed in the 1000-ton press, and forging experiments were started to determine the upper operating conditions of the system. A die temperature of 1700 F was used while forging parts under the full 1000-ton load of the press. No die deformation was detected under these conditions. A set of dies for use in the extrusion-forging process was cast of Inconel 713C. The evaluation of materials for use as 2400 F die materials was continued. Compression strength tests at 2400 F were conducted on TiB2, KT SiC, Ta2 Be17, Al2O3, high-density graphite, siliconized graphite, and commercial graphite.
