Abstract
A dispersionstrengthened copper DSC has been studied as an alternative material for railway brake discs to be used in severe railway braking applications Compared to standard steel the DSC shows a more homogeneous thermal field at the friction surface This also applies in depth both avoiding hot spots This thermal behaviour implies a lower wear and a very interesting friction coefficient evolution without any “antifade” phenomenon
