Abstract

The electrically conducting parts of electrical machines or appts. have hollow cavity is lines with a capillary layer contg. a cooling medium. The layer is of >=2 phase, practically eutectic alloy which on solidification from the melt has an open lamella or lattice structure and one of whose phases has been at least partly dissolved out. The alloy can be of a first (beta) Cy phase and a second (beta) intermetallic cpd. of Cu-E-phase such as a Cu-Zr-Si or Cu-Hf-Si cpd.
