    Abstract: The method comprising the following steps: a) Providing a first bath of a liquid metal (1) comprising aluminium with a content X and magnesium with a content Y, the magnesium content Y being different to zero, b) Immersing at least partially a sonotrode (3) formed from a material inert to liquid aluminium, in the first bath of liquid metal (1), and c) Applying power ultrasounds to the sonotrode (3) so as to excite the liquid metal (1) until wetting (5) of the sonotrode (3) by the liquid metal (1) is obtained. d) Cooling the first liquid metal (1) of the first bath until solidification of the first liquid metal (1) around the sonotrode (3) is obtained, generating an intimate bond (6) between the sonotrode (3) and the solidified first liquid metal (1) having a bonding strength substantially equal to that of brazing between two metals. e) Machining the solidified first metal (1) in the form of a flange (7) configured for the attachment of a mechanical amplifier and/or of a transducer (4).

    Abstract: Liquid metal degassing device comprising a chamber containing a liquid metal bath, a device for circulating a gas through a purification chamber and in that the purification chamber comprises a getter material configured to trap dihydrogen from the circulating gas. Method for degassing a liquid metal bath to reduce the hydrogen concentration of the liquid metal comprising the following steps



    a) Preparing a liquid metal bath, preferably an aluminum alloy
    b) Circulating a gas,
    c) Exchanging hydrogen from the circulating gas with the liquid metal such that the hydrogen dissolved in the liquid metal bath diffuses into the circulating gas and enriches the circulating gas with dihydrogen,
    d) Purifying the circulating gas enriched with dihydrogen in a purification chamber comprising a getter material configured to trap dihydrogen from the circulating gas.
