“…The temperature rise in ASBs was estimated to be 800 C-1600 C by measuring the geometry of elongated grains. The detailed estimation was given in the previous work [27] . It is above the temperature for dynamic recrystallization of 712C (~0.5 T m , T m is the melting point of the material) but below the melting point of 1425 C of AISI 52100 because of the absence of amorphous phase in the ASBs, a direct evidence of occurrence of melting.…”

“…Significant changes were found in the structure of crystal grains after severe plastic deformation with a rapid temperature rise to approximately 1000 °C termed "adiabatic shear bands" were investigated in past studies [53][54][55][56][57][58][59][60]. Li et al [59] analysed grain refinement in adiabatic shear bands occurring in AISI52100 steel using transmission electron microscope. In the first process of elongation of crystal grains, dislocation clusters and splitting parent grains changed into sub grains in dynamic recovery.…”

“…We considered two possible effects of the specific layer on the progress of scuffing. The first effect is a hardness reduction with shear rate under dynamic recrystallisation [53][54][55][56][57][58][59][60]. The second effect is to suppress chemical reaction of additives to the surface [42].…”

In Situ Observation of Crystal Grain Orientation During Scuffing Process of Steel Surface Using Synchrotron X-ray Diffraction

Scuffing is a catastrophic failure that causes significant surface damages such as plastic flow and welding with a marked increase in friction, wear, temperature and noise. In this study, variations in the crystal grain structure of a steel surface was analysed in situ during the scuffing process using a synchrotron X-ray diffraction system, combined with a visible camera and a near-infrared thermometer. The in situ observation system was synchronously operated to capture a contact area between a rotating sapphire ring and a stationary bearing steel pin. The Debye-Scherrer ring diffracted from the contact area was captured by a two-dimensional detector. The scuffing behaviour could be classified as either micro scuffing or macro scuffing. During the micro scuffing period, plastic flow occurred intermittently with a significant temperature rise of approximately 1000 °C. During the macro scuffing period, heat was continuously generated over the contact area. When plastic flow occurred, the captured Debye-Scherrer ring indicated the orientation of crystal grains as well as a phase transformation from martensite to austenite. This study constitutes the first in-situ observation of the behaviour of crystal grains in the dynamic recrystallisation process occurring during the scuffing process.
