Abstract (en)
[origin: WO2007039340A1] The invention relates to a method for producing a wear-resistant aluminum alloy, to an aluminum alloy produced according to the method, and to the use thereof. The method comprises the steps: (i) preparing an aluminum of the following composition: Fe: 3 - 10; X: 3 - 10; Y: 0 - 1,5; Z: 0 10, wherein X represents an element or a combination of elements: (a) V and Si; (b) Cr and Ti; (c) Ce, or; (d) Mn, with the provision that: the proportion of the individual elements in the combinations of elements (a) and (b) is equal to at least 0.5 % by weight; Y represents one or more grain refining elements selected from the group consisting of B, Ce, Sr, Sc, Mg, Nb, Mn and Zr provided that these are not provided as X; Z represents one or more additives, which increase a heat resistance and which is selected from the group of ceramic fibers, particles and platelets, and; the indications of % by weight refer to the alloy, and production-related impurities represent the remaining proportion of the alloy to total 100 % by weight, with the provision that the proportion of Al of the alloy is at least 80 % by weight; (ii) melting the aluminum alloy, dissolving and homogenizing the alloy elements at temperatures ranging from 650 °C to 1000 °C, and; (iii) pouring the melt into a casting mold at a casting temperature that, initially, is close to a melting temperature of the alloy and increases to a temperature of 150° higher than the melting temperature.
