摘要： Methods for producing a rotationally symmetrical, hollow metallic workpiece may involve rotating a casting mould about a rotation axis and introducing a melt into the casting mould. The melt may be thrown towards an inner contour of the casting mould by centrifugal forces, and hollow bodies may be added to the melt. Furthermore, a device for producing a rotationally symmetrical, hollow metallic workpiece may include a casting mould that is rotatable about a rotation axis, a feeder device for introducing a melt into the casting mould such that the melt is thrown towards an inner contour of the casting mould by the effect of a centrifugal force, and a metering device for adding hollow bodies to the melt.

摘要： A multilayer composite material may include at least one nonmetallic layer, which in some examples comprises plastic, and at least one metallic layer comprising a first metallic shape memory material. One problem with specifying multilayer composite materials and methods for producing multilayer composite materials relative to reshaping properties can be overcome by providing at least one second metallic layer and disposing the at least two metallic layers on opposite sides of the nonmetallic layer. Further disclosed are methods for producing multilayer composite materials, as well as semi-finished products produced from such multilayer composite materials. Still further disclosed are methods for producing components using such semi-finished products.

摘要： The invention relates to a tower of a wind power plant, having a lower part in the form of a lattice tower or truss tower with at least two corner bars, and an upper part in the form of a cross-sectionally substantially round tubular tower, wherein each particular corner bar is put together from a plurality of steel tube profiles that are connected together in the longitudinal direction. In order to achieve good transportability and easier assembly of the components of such a tower, the invention proposes a modular tower concept. According to the invention, each particular corner bar is in this case put together from at least three steel tube profiles which are provided with perforated flanges for holding screws, wherein the corner bars are connected together by cross struts and/or tension struts attached to the flanges, and wherein the steel tube profiles of each particular corner bar are spirally welded steel tube profiles.

摘要： Methods for producing a flat product from an iron-based shape memory alloy may involve casting a melt comprised of iron, alloying elements, and impurities into a strip having a thickness of 1-30 mm and cooling the melt as the strip is formed. A twin-roll caster may be employed to help cool and form the melt into the strip. The resultant flat product is highly resistant to bending and is robust under pressure and torsion.

摘要： A connector is disclosed for providing a positive and/or a non-positive connection between at least two connecting partners. The connector or connecting means has at least one first region which engages with the first connecting partner by way of a positive and/or a non-positive connection, and at least one second region is provided which engages with the at least second connecting partner by way of a positive and/or a non-positive connection. The connecting means provides a positive and/or non-positive connection between at least two connecting partners in a simple and inexpensive manner and which meets high safety requirements. The second region of the connecting means has a region which is formed from an at least partially flat material made of an Fe alloy with shape memory characteristics and which, when activated, ensures the positive and/or non-positive connection with the second connecting partner by way of a change in shape.
