Abstract

See full text

An additive method for preparing a large die blank for isothermal forging comprising preparing a plurality of titanium-zirconium-molybdenum alloy plate-shaped elements of a preset shape; preparing a plurality of foil-shaped intermediate layers of pure tantalum, a niobium-tungsten alloy and a tantalum-tungsten alloy of a preset shape; forming an assembly of a preset configuration, such that the foil-shaped intermediate layers are sandwiched between the titanium-zirconium-molybdenum alloy plate-shaped elements; applying an axial pressure to the assembly under high-temperature vacuum to perform diffusion connections to obtain a primary blank; subjecting the primary blank to a homogenization treatment under a high temperature, vacuum or inert gas protection to homogenize the structure and components at a connection interface in the primary blank; and cooling the homogenized primary blank to obtain a die blank.
