Mechanical attrition, mechanical alloying and reduction of the average
grain size are responsible for the building of the so called WEL (White
Etching Layer) in rolling contact by railway. This is observed with X-ray
and electron diffraction methods. A change of the thermodynamic,
mechanical and chemical properties has been observed with the properties
of nanophase materials.
