DE2551295

A dispersion strengthened aluminum alloy is produced by continuously casting an aluminum alloy containing 4 - 15% Si and other optional constituents in the form of a slab at a growth rate in excess of 25 cm/min. to solidify silicon in the form of elongated rods in a size range of 0.05 - 0.5 microns...

More Information
Summary:A dispersion strengthened aluminum alloy is produced by continuously casting an aluminum alloy containing 4 - 15% Si and other optional constituents in the form of a slab at a growth rate in excess of 25 cm/min. to solidify silicon in the form of elongated rods in a size range of 0.05 - 0.5 microns diameter. The cast slab is then subjected to at least 60% reduction to fragment the elongated silicon rods into finely divided particles, at least the final part of the reduction being effected by cold rolling, the cold-rolled sheet being subjected to a final annealing treatment at a temperature in the range of 250 DEG - 400 DEG C.
