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.
