Abstract (en)
[origin: EP0845542A1] Producing workpieces or semi-finished products of a wear resistant aluminium alloy containing intermetallic phase-forming additions involves: (a) casting the alloy melt to a body of small dimension to achieve a high cooling rate such that the precipitating intermetallic phase crystals are homogeneously distributed and have a defined size; (b) heating the body to temperatures in the heterogeneous molten aluminium/intermetallic phase region to produce sufficient melting of the aluminium that the body can flow under the force of gravity; and (c) shaping the body to a workpiece or semi-finished product of larger dimension.
