CARBIDE MORPHOLOGY AND FERRITE GRAIN SIZE AFTER ACCELERATED CARBIDE SPHEROIDISATION AND REFINEMENT (ASR) OF C45 STEEL

Original language description

The pearlite spheroidisation and grain refinement of the C45 steel was investigated. The ASR (accelerated carbide spheroidisation and refinement) process allows us to achieve a microstructure made of fine ferrite grains and globular carbides in seconds or minutes. This paper deals with the ASR process realization via the thermomechanical processing of controlled rolling. Hot rolling is a common part of structural steel processing. A conventional structure after the hot rolling of the C45 steel consistsof lamellar pearlite and ferrite. During controlled rolling with a deformation at temperatures around critical temperature A1, it is possible to achieve a microstructure of a fine ferritic matrix and globular carbides. The deformation causes a recrystallization of the ferritic matrix ? a grain refinement. Furthermore, a high dislocation density during the deformation enhances the diffusion and promotes carbide spheroidisation. The aim of the experimental program was to achieve a microstr
