STUDY BY ADVANCED X-RAY METHODS OF THE STRUCTURAL INHOMOGENEITY OF FERRITIC-MARTENSITIC STEELS
The structural inhomogeneity of ferritic-martensitic ODS steels was studied by use of X-ray methods of texture analysis, including the method of Generalized Pole Figures and the computer data treatment. The crystallographic orientation of grains is the most effective criterion for systematization of substructure inhomogeneities in textured materials. In this study the inhomogeneous distribution of the yttrium oxide particles in outside and inside layers of the deformed tube EP-450 ODS steel has been shown indirectly.
