A titanium aluminide alloy material for hot forging has a chemical composition including, by atom, aluminum of 38.0% or greater and 39.9% or less, niobium of 3.0% or greater and 5.0% or less, vanadium of 3.0% or greater and 4.0% or less, carbon of 0.05% or greater and 0.15% or less, and titanium and an inevitable impurity as a residue.

A device and method for producing a component are provided. The device or method includes steps or units for providing a first component element having a recess in or on a first surface of the first component element, and for positioning a second component element in the region of the recess. The device or method also includes a step or unit for pressing the first component element and the second component element together, and as a result forming a material fit, positive fit and/or non-positive fit between the first and the second component elements at least in the region of the recess. The positioning and the pressing can be carried out or are carried out functionally, in particular, spatially and/or temporally, in terms of equipment, separately from each other.

Certain exemplary embodiments can provide a manufacturing method, process, machine, and/or system for continuously consolidating granular materials, creating new alloys and/or composites, and/or modifying and/or refining material microstructure, by using plastic deformation of feedstock(s) provided in various structural forms. Materials produced during this process can be fabricated directly and/or in forms such as, e.g., wires, rods, tubes, sheets, plate and/or channels, etc.

A method for manufacturing a blade, the method includes casting a nickel alloy blade precursor having an airfoil and a root. The airfoil and the root are solution heat treating differently from each other. After the solution heat treating, the root is wrought processed. After the wrought processing, an exterior of the root is machined.

A mold of the present disclosure is used when forging a billet having a rod shape, and the mold includes: a lower mold having a groove portion for housing the billet; an upper mold having a pressing portion engaged with the groove portion and that presses the billet; and a guide portion disposed in the groove portion or the pressing portion and that guides a flow of a material of the billet in a longitudinal direction of the billet. In a state in which the groove portion and the pressing portion are engaged, in a direction in which the groove portion extends, a protruding amount of a top portion of the guide portion to an inner side of the groove portion is larger than a protruding amount of end portions on both sides sandwiching the top portion of the guide portion to the inner side of the groove portion.

The invention relates to an apparatus for material forming, by means of a tool (41) and a drive unit (2), the apparatus being arranged to move the drive unit (2) to provide kinetic energy to the tool (41), for the tool (41) to strike a work material (W), so as to form the work material (W), the apparatus being provided with an impact head (4″) between the drive unit (2) and the tool (41), and the apparatus being arranged to provide the kinetic energy to the tool by the drive unit (2) striking the impact head (4″), wherein at least a region of the impact head (4″) is allowed to move in relation to the tool (41) laterally to a direction of the stroke of the drive unit, whereby the impact head is arranged to expand laterally in relation to the tool. The invention also relates to a method for material forming.
