TLDR
In this paper, a method of making aluminium alloy is described, whereby the alloy contains Zr and from 0 to 1% of one or more of the elements Mg, Si, Ag, Ni and Cu, the balance being mainly Al.Abstract:
Aluminium alloy and a method of making it, whereby the alloy contains Zr and from 0 to 1% of one or more of the elements Mg, Si, Ag, Ni and Cu, the balance being mainly Al, the alloy being made on the basis of a melt which contains 0.5 to 2% by weight of Zr and which has been cast into particles by being cooled with such a high velocity that the Zr mainly is present in a supersaturated solution. The particles are consolidated and the Zr is precipitated as finely distributed dispersoids after a heat treatment at 300° to 450° C., and the alloy has an electrical conductivity of at least 58% IACS and a 10% softening temperature of at least 400° C. The consolidation may for instance be carried out by extrusion.read more
