dcterms:description
High pressure torsion (HPT) method with varying torsion strain was used in grain refinement of the medium carbon steel (45) at 400°C. The effect of effective strain εef, on mechanical properties and microstructure evolution was investigated. Due to strain varying various structures were found at the disc periphery and at disc axis in discs. Ultrafine grain structure was formed at the disc periphery, slightly deformed ferrite and modified pearlite lamellar structure vas found at the center of the disc even after the highest effective strain was applied. Conducting tensile tests, strength increase was observed with increasing equivalent strain εeq. The stress distribution and temperature distribution across disc as the effect of different applying εef were simulated using DEFORM 3D method.
