Abstract
The formation of a submicrocrystalline structure is shown to substanti ally increase the strength of 15Kh25T ferritic steel and retain suffic ient ductility. In the fragmented state the strength (sigma 0.2 UTS) i s higher compared to submicrocrystalline state. Grain refinement to su brmicron range significantly changes the character of plastic flow of the steel.
