Forming of C45 Steel at Critical Temperature
Original language description
An important measure in steel processing industry is achieving the required mechanical properties and microstructure of the material. A new phenomenon has been discovered recently which allows to refine ferrite grain significantly and to spheroidise carbides over a very short time compared to conventional heat treatment techniques. The newly developed technology based on the ASR (Accelerated Spheroidisation and Refinement) effect consists in heating a steel workpiece through thickness to a temperature no higher than Ac1 and in subsequent plastic deformation. Fully austenitized regions, partially austenitized regions, and areas where no phase transformation occurred, coexist. In locations previously subjected to intensive plastic deformation, cementitelamellae disintegrate and globular carbides form. In regions subjected to milder plastic deformation, spheroidisation does not occur directly in the course of the thermomechanical treatment. Despite, the cementite lamellae show a stronger
