Abstract
Bearing ring blanks of the high-speed rail bearings, machine tool spindle bearings and wind power bearings have been manufactured through the ring rolling technology. Yet, the plastic deformation and microstructure evolution of bearing ring blanks during the cold rolling process remains unclear. In this work, the deformation and damage evaluation of bearing ring blanks made of GCr15 bearing steel are characterised by the electron backscatter diffraction (EBSD) technique. Furthermore, their microstructure changes in cold rolling are investigated through band contrast images, and their texture evolutions after various deformation ratios are analysed by the technique of 3D-Euler space distribution. This work provides valuable guidelines for enhanced understanding the role of the cold rolling technology on the microstructure evolution of bearing ring blanks.
期刊介绍:
IJCMSSE is a refereed international journal that aims to provide a blend of theoretical and applied study of computational materials science and surface engineering. The scope of IJCMSSE original scientific papers that describe computer methods of modelling, simulation, and prediction for designing materials and structures at all length scales. The Editors-in-Chief of IJCMSSE encourage the submission of fundamental and interdisciplinary contributions on materials science and engineering, surface engineering and computational methods of modelling, simulation, and prediction. Papers published in IJCMSSE involve the solution of current problems, in which it is necessary to apply computational materials science and surface engineering methods for solving relevant engineering problems.
