Description
Summary:The basic die assembly previously constructed for prototype work is satisfactory for support ing the actual working dies and their retainer rings. The material selections have been made for these parts and will utilize a self-bonded SiC as the upper male die, an 85% W-15% Mo cast lower die, and the 97% W-15% Mo retainer ring assembly for both dies. The attainment of 2400 F at the male die insert and 2300 F at the bot tom die cavity has been demonstrated using a combination of electrical resistance heating in the die base and flame heating of the die im pressions. Protection of the metallic dies at these temperatures is by means of a CaF-NaF salt mixture. (Author)
