Sažetak
Commercial low carbon steel AISI 1010 was subjected to a severe plastic deformation technique called Equal Angular Channel Pressing (ECAP) at different increased temperatures. The paper describes the refinement of a course grained microstructure to submicrocrystalline structure by high strain plastic deformation. As temperature of ECAP straining is increasing the process of dynamic polygonization and recrystallization proceeds more effectively and subcrystalline structure is formed by sectioning of ferrite elongated grains. The size of newly born polygonized grains is in range of 300 - 500 μ m. The warm ECAP of the low carbon steel under specific testing condition leads to the formation of predominantly submicron grain structure. The formation of such of predominant submicrocrystalline structure resulted in significant increase of yield stress and tensile strength of the steel.
