It is clear that the spin at the tread of drive wheels appear always. Under operation conditions a phenomenon of macro slip and side slipping is especially undesirable and harmful, since it causes an excessive wear of rolling wheel surfaces owing to generation of such defects as spallings, shellings, flat places etc. The better knowledge about the process of formation of martensite around a wheel flat, and about the ensuing spalling, will facilitate money-saving improvements in material of wheel and will enable to increase safety.
