Abstract in different language: In order to achieve specific mechanical properties and structures of a material, a combination of new technologies together with an unconventional use of different types of materials could be an asset. Powder metallurgy, involving a metal matrix and dispersed stable particles, in combination with mechanical alloying and hot consolidation could be a solution. This paper describes the thermomechanical characteristics of new oxide-dispersion-strengthened (ODS) alloys with a Fe-Al matrix in terms of changes in the grain-size distribution. Recrystallization and grain growth were investigated over a range of temperatures and deformations. The results show that the grain-growing process in the new ODS alloys is significantly affected by the thermomechanical treatment, leading to the maximum grain size within 20-h annealing at 1200 °C. They are analysed using different methods, including optical microscopy.
