Abstract (en)

[origin: EP0902095A2] The damping capacity of a cast light-metal component is increased using an additional element which is an alloy with high damping capacity, and takes the form of a wire fabric serving as a casting insert. The damping capacity is increased as a result of longitudinal elastic deformations which occur within the joint regions between the light-metal matrix and the heavy-metal wire when energy (in the form of sound or vibration) enters into the component.
