Abstract
The invention relates to novel casting wheels for the rapid solidification technique which are produced by centrifugal casting. The wheels are made of an alloy with a non-equiaxial granular structure, wherein the grains are elongated and their longitudinal axis lies substantially perpendicular to the casting-wheel surface.
Claims13
A rotationally symmetric casting wheel having a quench surface, said casting wheel operable for the production of amorphous and/or microcrystalline metal ribbons by rapid solidification, said casting wheel comprising a thermally conducting centrifugal casted alloy with a texturized grain zone comprising non-equiaxial grains that are longitudinally extended, each of which has a long axis, with a substantial portion of the long axis oriented essentially perpendicular to the quench surface of the casting wheel.
