  • Patent number: 11701804
    Abstract: A method for producing a part in the form of a solid block from a natural material in particulate form containing scleroproteins. A phase of heating the natural material, under compression at a pressure greater than or equal to 30 MPa, to a temperature greater than or equal to the denaturation temperature of the scleroproteins contained in the material. A phase of cooling the material thus obtained to a temperature less than 100° C., while maintaining the compression during at least a part of the cooling phase.
    Type: Grant

  • Patent number: 11045873
    Abstract: The invention relates to a method for manufacturing a metal, ceramic, or composite part (PF) by flash sintering, which comprises simultaneously applying, inside a die (M), a uniaxial pressure and an electric current to a device containing a powder constituent material, said uniaxial pressure being applied by means of at least two pistons (P1, P2) which slide toward one another inside said die and each of which has a bearing surface (F1, F2) contacting said material, said bearing surfaces engaging so as to define the shape of the part to be manufactured, characterised in that: said part has a complex shape, including at least one first slender portion (V), such as a rod, plate, bevel, or shell, and a second portion (B), such as a base, plinth, or solid part, which is not slender in the slender direction of said first portion, and in that said uniaxial pressure is applied in a direction (z) substantially parallel to the smallest dimension of said first portion of the part, or to one of the two smallest dimensio

  • Patent number: 10183331
    Abstract: A method manufactures a metal alloy part by spark plasma sintering. The method includes the simultaneous application, inside a die, of a uniaxial pressure and of an electric current to a powder component material that has the following composition: 42 to 49% aluminum, 0.05 to 1.5% boron, at least 0.2% of at least one element selected from tungsten, rhenium and zirconium, optionally 0 to 5% of one or more elements selected from chromium, niobium, molybdenum, silicon and carbon, the balance being titanium and the total of the elements without aluminum and titanium being between 0.25 and 12%.
