    Abstract: A system for controlling the progress of the manufacture of at least one product by vertical semi-continuous direct chill casting, in particular from aluminium alloy, in a fixed mold, the control system includes a dummy bottom configured to form a movable lower bottom of the fixed mold and to carry the product during casting; a weighing cell, on which the dummy bottom is arranged to rest, the weighing cell being configured to take measurements representative of the mass of the product carried by the dummy bottom during casting; and a support of the dummy bottom, to which the weighing cell is linked, configured to lower the false bottom relative to the fixed mold, substantially in a vertical direction, during casting; and a processing unit connected to each weighing cell, and configured to process the measurements, and calculate the variation in the mass of the product over time.

    Abstract: The method comprises the following steps: a) Providing a sonotrode (1) formed from an essentially inert material with respect to the liquid metal, such as a ceramic, and preferably a silicon nitride or a silicon oxynitride, such as SIALON, or a metal essentially inert to said liquid metal, b) Immersing at least partially the sonotrode (1) in a bath of said metal, c) Applying to the sonotrode (1) power ultrasounds, particularly ultrasounds having a power greater than 10 watts to obtain the wetting of said sonotrode by said metal, d) Applying continuously to the sonotrode (1) measurement ultrasounds, also known as testing ultrasounds, particularly ultrasounds wherein the frequency is between 1 and 25 MHz, e) Applying intermittently to the sonotrode (1) power ultrasounds, particularly ultrasounds having a power greater than 10 watts, to maintain said wetting.

    Abstract: A process for manufacturing a bimetallic part by means of a first component formed by a first aluminum alloy and a second component formed by a second aluminum alloy, said process involving: assembling the first component and the second component to obtain an assembled part; applying a thermal treatment to the assembled part at a temperature of 100 to 250° C., the thermal treatment causing the assembled part to deform, in particular as a result of a metallurgical deformation by a precipitation of hardening phases of the first component and/or the second component; cooling the part to ambient temperature, upon which the part remains deformed. The process involves, prior to the assembling step, an estimation of the degree of deformation that the assembled part will undergo under the effect of the thermal treatment.

    Abstract: The invention involves a method for testing a damage tolerance property in an aluminum alloy part with the following steps:



    measure at least one property representative of a the part's tensile strength;
    use the property measured in step a) as input datum (xi) of a neural network estimator;
    estimate, using the estimator, the representative property of the part's tensile strength; the method being characterized in that it includes:
    consideration of an acceptance threshold and comparison of the property estimated at step c) to the acceptance threshold, taking into account a confidence interval;
    based on the comparison:

    consider that the part passes the test;
    or consider that the part does not pass the test.
