Development of ultrafine structure in steels in conditions of severe plastic deformation ECAP

Popis výsledku v původním jazyce

The article focuses on the results from recent experimental of severe plastic deformation (SPD) of low carbon steel AISI 1010 and medium carbon steel AISI 1045 performed at increased temperatures. The grain refinement of ferrite respectively ferrite-pearlite structure is monitored and described. While LC steel was deformed by ECAP die with a channel angle ? = 90° and by strain ?ef = 3. The ECAP severe deformation of MC steel was conducted with die channel angle of 120° and ?ef = 2.6 - 4) and TECAP - 400°C. The high straining in LC steel resulted in extensively elongated ferrite grains with dense dislocation network, and randomly recovered and polygonized structure was observed although. The small period of work hardening appeared at tensile deformation. On the other side, the warm ECAP deformation of MC steel in dependence of increased effective strain resulted in more progressive recovery process in deformed structure. In interior of the elongated ferrite grains the subgrain structure
