Provided is a tantalum target, wherein, when a direction normal to a rolling surface (ND), which is a cross section perpendicular to a sputtering surface of a target, is observed via an electron backscatter diffraction pattern method, an area ratio of crystal grains of which a {100} plane is oriented in the ND is 30% or more. An object of the present invention is to provide a tantalum sputtering target in which a deposition rate can be appropriately controlled under high-power sputtering conditions. When sputter-deposition is performed using this kind of a tantalum target, it is possible to form a thin film having superior film thickness uniformity and improve the productivity of the thin film formation process, even for micro wiring.

Solution heat treatment is performed on a blank to dissolve initial coarse secondary phases, to obtain a uniform solid solution microstructure. The blank subjected to the solution heat treatment is transferred into the temperature-controllable forming die to be stamped and quenched. During forming, the temperature and the pressure are further maintained for a period of time. The temperature of the forming die is adjusted to a second-step aging temperature for the second-step aging treatment. In a two-step aging temperature range, stress relaxation occurs while strengthening precipitates are rapidly precipitated, thereby improving strength and dimensional accuracy of the formed part. On the premise of ensuring quality of the formed part, employing stepped aging treatment shortens the aging cycle and reduces energy consumption in the production and manufacturing process..

A method of a forming a hollow, drug-eluting nitinol stent includes shaping a composite wire into a stent pattern, wherein the composite wire includes an inner member, a nitinol intermediate member, and an outer member. After the composite wire is shaped into the stent pattern, the composite wire is heat treated to set the nitinol intermediate member in the stent pattern. After heat treatment, the composite wire is processed to remove the outer member and the inner member without adversely affecting the intermediate member. Openings may be provided through the intermediate member and the lumen of the intermediate member may be filled with a substance to be eluted through the openings.

Producing a Ni superalloy component in which the superalloy has a γ phase matrix containing intermetallic γ′ precipitates. Providing a Ni superalloy casting of the component; solutioning the component by heat treating the casting under vacuum and/or in an inert atmosphere at a temperature above the γ′ solvus to homogenize the γ phase; quenching and ageing the solutioned component to grow intermetallic γ′ precipitates in the homogenized γ phase.
