Abstract (en)

[origin: ES2000175A6] The invention concerns Al-base alloys with substantial proportions of Li and Si, containing, by weight: from 3.6 to 8% Li from 5 to 14% Si from 0 to 1% of each of the following optional elements: Fe, Co, Ni, Cr, Mn, Zr, V, Ti, Nb, Mo, O2, Sc, and from 0 to 2% of each of the optional elements Cu, Mg and/or Zn, the total amount of the optional elements being less than 5%, and the balance being Al and impurities, each impurity</=0.05%, with total impurities</=0.15%. The products are obtained by rapid solidification processes and contain from 15 to 60% by volume of phase T (Al, Si, Li), in the form of particles of from 0.01 to 10 mu m.
