ANALYSIS OF THE THERMAL CONDITIONS FOR THE FORMATION OF MARTENSITE BY FRICTION

ANALYSE DER THERMISCHEN BILDUNGSBEDINGUNGEN VON REIBMARTENSIT

A mathematical model based on electrical-circuit equivalence and used to calculate the minimum heat-flux density required for the formation of martensite at the surface of railroad rail steel by friction is decribed. With this model, it is also possible to determine the thickness of the friction-martensite layers. Conclusions drawn from the results are applicable to the formation of the brittle martensite on rails and the wheels of railroad rolling stock, such as freight cars, by braking and engine burns. Other applications are briefly discussed.
