摘要： A process for manufacturing a turbine engine component (10) comprises the steps of: casting ingots made of a gamma TiAl material using a double vacuum arc remelting casting technique; subjecting the cast ingots to a hot isostatic pressing to close porosity; forming at least one pancake of the gamma TiAl material by isothermally forging the hot isostatic pressed ingots; sectioning each pancake into a plurality of blanks; heat treating the blanks to produce a desired microstructure and mechanical properties; and machining the blanks into finished turbine engine components (10). A system for performing the process is also disclosed.

摘要： The invention relates to metal forming using diffusion welding and superplastic forming. Stop-off material is preliminarily applied in a predetermined screen pattern to areas where surfaces of skin and core preforms come into contact. Skin preforms are provided with a groove, and core preform is provided with a slot for mounting at least one tube. A stack is sealed along edges with the exception of where at least one tube is to be mounted. A tube is mounted to be connected to a collector zone, and oxygen and binder of the stop-off material are removed from cavities in the stack. The stack is fully sealed, heated, and the preforms are diffusion-welded in predetermined areas, also along an entrance edge, an exit edge and a peripheral edge. An integral structural preform is given an airfoil shape and subjected to superplastic forming by supplying working fluid into cavities between the skin and core preforms through also at least one tube. The collector zone is disposed on the side of the stack, which corresponds to the peripheral edge of the blade. For mounting one or more tubes for supplying working fluid at superplastic forming, the groove in the skin preforms and the slot in the core preform are provided at a distance from the outer boundary of the entrance edge or exit edge less than L/3, where L is the length of the blade chord along the peripheral edge. It is thus possible to eliminate risk of defects during blade forming without compromising performance characteristics of the blade and increase in labor intensity of producing same.

摘要： Provided are a manufacturing method for a blade material and a manufacturing device for a blade material, by which a long blade material can be manufactured without using a large-sized press forging machine. A manufacturing method for a blade material, in which hot forging is sequentially performed by molds from the root side to a blade (vane) tip, wherein when a root-side portion is grasped and a material to be forged is restrained by a mold, twisting is performed on a region between the grasped portion and the restrained portion. A manufacturing method for a blade material, in which hot forging and twisting are repeated, is preferable, and a manufacturing method for a blade material, in which hot forging is performed while molds are sequentially changed, is more preferable.
