Severe operating conditions in terms of high speed with heavy braking loads and elevated temperature gradients
together with continued environmental exposure can affect the operability and the performance of
wrought and cast brake discs of automotive vehicles such as passenger cars [1–5], trucks [6], motorcycles
[7], etc., causing their failure by thermal fatigue. These situations often occur in considering fire fighting motor
vehicles used in supporting to the flight activities that must operate in very short time at high speed, i.e. less
than 2 min and about 100 m/s, respectively
