摘要： A method for producing a reinforced alloy powder containing a metal matrix in which crystalline oxide particles are dispersed, including: (i) providing a powder mixture including a parent metal powder including a master alloy for forming the metal matrix and an additional powder including an intermediate; (ii) milling the powder mixture by a mechanical synthesis process to make a precursor powder; and (iii) subjecting the precursor powder to a thermal plasma generated by a plasma torch including a plasma gas. The master alloy is iron-based, nickel-based, or aluminum-based. The intermediate is at least one of YFe3, Y2O3, Fe2O3, Fe2Ti, FeCrWTi, TiH2, TiO2, Al2O3, HfO2, SiO2, ZrO2, ThO2, and MgO. In (iii), the precursor powder is injected into the plasma torch at a flow rate of 10-30 g/min, a power of the plasma torch is 20-40 kW, and a pressure in a reaction chamber of the plasma torch is 25-100 kPa.

摘要： Process for the manufacture 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 μm to 50 μm.
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.

摘要： A metallic filter (1) includes a microstructured architecture (2) defined in a three-dimensional space having orthogonal axes, microstructured architecture (2) includes a metallic network (10) formed by a plurality of longitudinal connecting strands (12), namely extending along a longitudinal axis direction (X), and a network (20) of pores formed of a plurality of longitudinal interstices (22) located along connecting strands (12). Each longitudinal interstice corresponding to a subset of pores (24) of the network (20) of pores. The subset of pores (24) for which the pores are aligned along the longitudinal axis (X), the longitudinal interstices (22) thereby defining an axis of anisotropy of the microstructured architecture.
