FIELD: powder metallurgy, in particular aluminum-based alloys for welded constructions.
SUBSTANCE: invention relates to aluminum-based alloy of general formula AlaZnbMgcZrd(Al2O3)eMf, wherein Mf is Cum and/or at least one element selected from Scg, Mnh, Tii, Nij, Cok, Crl; a, b, c, d, e, f, g, h, I, j, k, l, and m represent atomic %, wherein a = 92.0-94.5; b = 2.1-3.1; c = 3.4-4.7; d = 0.09-0.26; e = 0.01-0.2; f = 0.42-1.0; g = 0.18-0.4; h = 0.15-0.28; i = 0.08-0.15; j = 0.07-0.01; k = 0.07-0.2; l = 0.05-0.30, and m = 0.1-0.7. Alloy is obtained from compacted and consolidated water-pulverized quickly crystallized powders consisting particles of awkward shape, complex surface relief and nonuniform oxide film thickness. Alloy has highly refined cellular structure and contains reinforcing phases of metastable intermetallic compounds.
EFFECT: alloy and welded constructions of increased strength.
