Evolution of Microstructure during Hot Deformation of Pearlitic Steel

Abstract:

Hot deformation of pearlitic steel was carried out to examine the overall deformation response to micro structural and texture evolution. To understand the mechanisms operative during hot deformation, compression tests were carried out at various temperatures in the range 400 - 600o C and strain rates in the range 0.001-10 s-1. The flow curves were analyzed to examine the occurrence of dynamic recrystallization. The evolution of microstructure and texture of hot deformed sample is analysed using EBSD and X-ray texture goniometer respectively.
