Abstract: 【Objective】Tribologically transformed structure (TTS) is an important characteristic structure, which is
generated by the friction surface. More narrowly conceived, the TTS is usually regarded as a hardened layer formed on
the surface of the tribo-pairs, which is a hardened layer with ultra-fine grains, high hardness and brittleness, and no
obvious characteristics under optical microscopy, but not easily etched relative to the substrate. The TTS layer is also a
typical damage characteristic induced by the rolling contact process of wheel-rail system. Its occurrence, development
and evolution process have an important influence on the failure behaviors of wheel-rail interface, including surface
wear, delamination, squat-type defect, fatigue crack initiation and propagation in the near surface. In the field of railway,
white and brown layers are common tribologically transformed structure, which usually appear at the wheel-rail contact
interface and involve changes in the microstructure of materials, and widely exist in various operating railway lines.
