<p>PCT No. PCT/EP96/03779 Sec. 371 Date Feb. 27, 1998 Sec. 102(e) Date Feb. 27, 1998 PCT Filed Aug. 28, 1996 PCT Pub. No. WO97/09458 PCT Pub. Date Mar. 13, 1997The invention relates to a method for manufacturing thin-walled pipes, which are made of a heat-resistant and wear-resistant aluminum-based material. The method comprises the providing of a billet or a tube blank made of a hypereutectic aluminum-silicon AlSi material, possibly a subsequent averaging annealing, the extruding of the billet or of the tube blank to a thick-walled pipe, and the hot deformation of this pipe to a thin-walled pipe. Such a method is in particular suited for the production of cylinder liners of internal combustion engines, since the produced liners exhibit the required properties in regard to wear resistance, heat resistance and reduction of pollutant emission.</p> |
