A dispersion-strengthened 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 “anti-fade” phenomenon.
