Deformation of hadfield steel single crystals by dry sliding friction with the normal load/friction force orientations [(11)over-bar0]/[(1)over-bar10] and [(11)over-bar0][001]

摘要

This paper studies the friction and wear of Hadfield steel single crystals with the normal load/friction force orientations [(11) over bar0]/[(1) over bar 10] and [(11) over bar0][001]. Due to the different friction force orientation, deformation occurs by twinning in the first case and by slip in the second case. The shear stresses were estimated and correlated with the observed slip band systems. Changes in the orientation of the worn surface were examined by EBSD analysis. TEM studies were performed to investigate the dislocation structure evolution near the worn surface.
