Abstract: An ultrasound system for processing of liquid metal and their alloys, comprising at least one ultrasound transducer (301, 401, 501, 601, 701, 701a, 801a, 801b, 801c, 801d, 801e, 901, 1001) and at least one composite waveguide (302, 402, 502, 602, 702, 802, 902, 1002a-c) made of a composite material comprising a reinforcement and a matrix. The ultrasound transducer (301, 401, 501, 601, 701, 701a, 801a, 801b, 801c, 801d, 801e, 901, 1001) is coupled with the composite waveguide (302, 402, 502, 602, 702, 802, 902, 1002a-c)so that during operation it excites a standing wave of mechanical vibrations in the composite waveguide (302, 402, 502, 602, 702, 802, 902, 1002a-c). 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.
