ABSTRACT:
When used, a hot extrusion forging die for use in titanium alloy according to the present invention extrusion works a heated titanium alloy-made billet in such a manner as to diameter-reduce the billet. The hot extrusion forging die for use in titanium alloy according to the present invention is equipped with a die member for extrusion working. The die member is made of ceramic. The forging die according to the present invention makes it possible to suppress the sticking of the die member onto an extruded work to thereby make it easy to take out the extruded work. Also, the forging die according to the present invention makes it possible to suppress the seizure of the titanium alloy-made billet, with the result that there can be used a lubricant for which the removing operation is not needed to be done.
