  • Method for manufacturing a metal workpiece limiting the appearance of recrystallized grains in said workpiece
    Patent number: 11772155
    Abstract: A method for manufacturing a metal workpiece by casting a metal alloy in a mould, in which prior to the casting, a chart is determined providing a risk of appearance of recrystallised grains during the casting and/or solidification of the metal workpiece, depending on temperature and plastic deformation energy conditions undergone by the metal workpiece, the casting of the metal alloy in the mould being implemented under casting and solidification conditions determined using the chart in order for the temperature and plastic deformation energy conditions undergone by the metal workpiece to be less than a given threshold for the risk of appearance of recrystallised grains.
    Type: Grant

  • METHOD FOR MANUFACTURING A METAL WORKPIECE LIMITING THE APPEARANCE OF RECRYSTALLIZED GRAINS IN SAID WORKPIECE
    Publication number: 20220379371
    Abstract: The present invention concerns a method for manufacturing a metal workpiece by casting a metal alloy in a mould, wherein prior to the casting, a chart is determined providing a risk of appearance of recrystallised grains during the casting/solidification of the metal workpiece, depending on temperature and plastic deformation energy conditions undergone by said metal workpiece, the casting of the metal alloy in the mould being implemented under casting and solidification conditions determined using the chart in order for the temperature and plastic deformation energy conditions undergone by the metal workpiece to be less than a given threshold for the risk of appearance of recrystallised grains.
