Grain refinement of low karbon steel by ECAP severe plastic deformation

Popis výsledku v původním jazyce

The aim of this work is to evaluate the effect of initial structure modification and increased temperature on ultrafine grain structure formation of commercial low carbon steel AISI 1014. Two different initial structural states of the steel were preparedusing thermal and thermomechanical treatment. The purpose of thermomechanical treatment was to refine the initial grain size in steel. The ultrafine grain structure was prepared by applying method severe plastic deformation ECAP with different level ofstraining at increased temperature. The impact of different effective strain ?ef introduced upon microstructure changes was investigated using light, scanning (SEM) and transmission electron microscopy (TEM) methods. The microhardness results (HV) alongthe deformed supported the microstructure development. Repeating deformation procedure (Bc) the coarse and modified (by TM) ferrite grains were refined and resulting structure was the mixture of fine grains having high angle boundaries. T
