  • Publication number: 20210230722
    Abstract: A method for producing a powder of a reinforced alloy (ODS alloy) in which the grains forming the particles of the powder comprise a metal matrix, in the volume of which crystalline oxide particles are dispersed, said method comprising the following successive steps: i) providing a powder mixture to be milled comprising a master alloy intended to form the metal matrix and an additional powder comprising at least one intermediate intended to incorporate atoms intended to form the dispersed oxide particles; ii) milling the powder mixture according to a mechanical synthesis process for making a precursor powder; iii) subjecting the precursor powder to a thermal plasma generated by a plasma torch comprising a plasma gas, in order to obtain the reinforced alloy powder. The method of the invention is particularly suitable for producing an ODS alloy that has optimized characteristics of composition and/or microstructure.

  • Publication number: 20210138544
    Abstract: Process for the treatment of a steel material, wherein the grains of which it is composed comprise a matrix into which precipitates are incorporated, the precipitates comprising at least one metallic element selected from a metallic element M, a metallic element M?, a metallic element M? or mixtures thereof; the microstructure of the steel being such that the grains are equiaxial and the average size of the grains being such that the average of their largest dimension “Dmax” and/or the average of their smallest dimension “Dmin” is in the range 10 ?m to 50 ?m. The steel material has optimised, stable and isotropic mechanical properties, in particular so that the steel material is more resistant to mechanical and/or thermal stresses.

  • Publication number: 20210140022
    Abstract: Steel material whose constituent grains comprise a matrix in which precipitates are incorporated, the precipitates comprising at least one metallic element selected from a metallic element M, a metallic element M?, a metallic element M? or mixtures thereof; the microstructure of the steel being such that the grains are equiaxed and the average grain size being such that the average of their largest dimension “Dmax” and/or the average of their smallest dimension “Dmin” is comprised between 10 ?m and 50 ?m. The steel material has optimized, stable and isotropic mechanical properties, in particular so that the steel material can best withstand mechanical and/or thermal stresses.

  • Publication number: 20210140025
    Abstract: Part comprising a steel material whose constituent grains comprise a matrix in which precipitates are incorporated, the precipitates comprising at least one metallic element selected from a metallic element M, a metallic element M?, a metallic element M? or mixtures thereof; the microstructure of the steel being such that the grains are equiaxed and the average grain size being such that the average of their largest dimension “D max” and/or the average of their smallest dimension “D min” is comprised between 10 ?m and 50 ?m. The steel material has optimised, stable and isotropic mechanical properties, in particular so that the steel material can best withstand mechanical and/or thermal stresses.
