Název v původním jazyce

Deformation behaviour and ultrafine grained structure development in steels with different karbon kontent subjected to severe plastic deformation

Popis výsledku v původním jazyce

The paper focuses on the results from recent experimental of severe plastic deformation of low and medium carbon steels performed at increased temperatures. The grainc refinement was executed by ECAP with die channels of 90°and 120°. The high straining introduced in LC steel resulted in extensively elongated ferrite grains with dislocation cell structure. Randomly recovered and polygonized structure was observed. At ECAP experimental of medium carbon steel performed at temperature of 400°C the more progressive structure recovery process was apparent. As number of ECAP passes increased the dynamic polygonization and recrystallization became active to form mixture of polygonized and submicrocrystalline structure. The favorable effect of ferrite-pearlitestructure modification was reason for extended work hardening phenomenon observed at steel with higher content of carbon.
