ABSTRACT:
The present invention relates to alloys in which the essential constituent is aluminum, metal deposits produced from these alloys, substrates coated with these alloys and the applications of these alloys. The alloys of the present invention are characterized in that they have the following atomic composition: Al.sub.a Cu.sub.b Co.sub.b, (B,C).sub.c M.sub.d N.sub.e I.sub.f, a+b+b'+c+d+e+f=100, expressed as number of atoms, a.gtoreq.50, 0.ltoreq.b<14, 0.ltoreq.b'.ltoreq.22, 0<b+b'.ltoreq.30, 0.ltoreq.c.ltoreq.5, 8.ltoreq.d.ltoreq.30, 0.ltoreq.e.ltoreq.4, f.ltoreq.2, where M represents one of more elements chosen from Fe, Cr, Mn, Ni, Ru, Os, Mo, V Mg, Zn and Pd; N represents one or more elements chosen from W, Ti, Zr, Hf, Rh, Nb, Ta, Y, Si, Ge and the rare earths; I represents the inevitable production impurities; and they contain at least 30% by mass of one or more quasicrystalline phases.
