Abstract
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.
