An ultrasound system for processing of liquid metal and their alloys, comprising at least one ultrasound transducer and at least one composite waveguide made of a composite material comprising a reinforcement and a matrix. The ultrasound transducer is coupled with the composite waveguide so that during operation it excites a standing wave of mechanical vibrations in the composite waveguide. According to the invention, the matrix comprises a metallic and/or ceramic material whereas the reinforcement comprises fibers of metallic and/or ceramic material. Mechanical vibrations are transverse to the fibers of the reinforcement material. A method of processing of materials, in which material is melted and the melted material is subjected to the operating of a vibrating waveguide in the ultrasound system, characterized in that the ultrasound system according to the invention is used.

Ultrasound system for metals and their alloys processing and method of liquid metals and their alloys processing

An ultrasound sonotrode (), the first end of which is adapted to be connected to a mechanical vibrations source, equipped with a working tip () at the opposite end of the sonotrode (), equipped with a body () with a cooling jacket (), sealed at the place of contact with the body () of the sonotrode () with the use of the first seal () and the second seal (), characterized in that according to the invention the first seal () is placed at a distance less than or equal to 20 mm from the node of the standing wave excited in the sonotrode in the working conditions, and the second seal () is equipped with a resilient element () and is located at a distance less than or equal to 20 mm from the working tip (). A method for metal alloying, in which the material is melted on the working tip () of the sonotrode excited to mechanical vibrations, according to the invention characterized in that a sonotrode according to the invention is used.
