The two ways of oxide dispersion creation were verified: direct adding of oxide powders (alumina or yttria) and internal oxidation of oxidizable elements (aluminium or yttrium) by adding the gaseous oxygen to the alloyed powder. ODS steels prepared by both methods have comparable mechanical properties, therefore it was proven that the internal oxidation method can be used for a preparation of the ODS steel. This is especially applicable in the case of hard and abrasive oxides (e.g. alumina) which do not erode during mechanical alloying and do not create fine dispersion.
