Abstract: A power semiconductor module, and method for its manufacture, comprising a first housing part having a cutout and a DC voltage load connection apparatus forming a structural unit, wherein the DC voltage load connection apparatus has first and second DC voltage load connection elements. The first DC voltage load connection element has a first leadthrough section arranged in the cutout, and the second DC voltage load connection element has a second leadthrough section arranged in the cutout forming a gap therebetween. The first and second leadthrough sections are sheathed by an elastomer, which fills the gap, is cohesively connected to the first and second leadthrough sections and seals off the first and second leadthrough sections with respect to the first housing part. The inventive power semiconductor module exhibits a high resistance to thermal cycling, and the distance between the DC voltage load connection elements can be configured to be small.

Abstract: A high-temperature component made of a nickel super-alloy has the following composition in wt %: 11-13% of Cr, 3-5% of W, 0.5-2.5% of Mo, 3-5% of Al, 3-5% of Ti, 3-7% of Ta, 1-5% of Re and a remainder of nickel.

Abstract: A high-temperature component made of a nickel super-alloy has the following composition in wt %: 11–13% of Cr, 3–5% of W, 0.5–2.5% of Mo, 3–5% of Al, 3–5% of Ti, 3–7% of Ta, 1–5% of Re and a remainder formed of nickel. A corresponding component which is also provided is formed of an alloy having a composition essentially similar to that mentioned above, but with the rhenium proportion replaced with 0.1–5 wt % of ruthenium.

Abstract: To prevent movement of a ceramic core in a ceramic shell for the investment casting of a turbine blade, the free end of the core has one or more pins embedded therein so that the pins project into both the core and the ceramic shell which is applied over a wax layer. After removal of the wax and firing of the shell, molten metal is cast in the space left by the wax between the core and the shell. After hardening of the metal, the outwardly projecting part of the pins are removed during the machining of the surfaces of the turbine blade blank.
