PROCESS FOR OBTAINING DISPERSION-HARDENED ALUMINUM ALLOYS

摘要

Dispersion strengthened aluminum alloy products are produced by working a cast aluminum alloy having a content of unaligned intermetallic rods in a selected size range to break up the brittle intermetallic rods. The intermetallic rods form 5.0 - 20 per cent by volume of the alloy and have an average diameter in the range of 0.1 - 1.5 (preferably 0.1 - 0.8) microns.
