Abstract
"PROCEDURE FOR THE PERMANENT MODIFICATION OF EUTECTIC ALUMINUM-SILICON ALLOYS AND NEXT TO THE EUTECTIC", characterized in that the Al-Si alloy is melted next to the eutectic in a graphite-clay crucible. Si composition between 11 and 13%. Once the metal has acquired a temperature between 680ºC to 780ºC, the mixture of salts wrapped in aluminum foil is added, introducing it to the bottom of the crucible, with a perforated bell of graphite or iron, the latter being duly protected. The mixture of salts, formed by Cl2Sr and FNa, previously had to be melted and homogenized, and after cooling it is pulverized. It must be kept in a container free of moisture. The amount of salts to be added is that necessary to introduce a proportion of strontium between 0.1 and 1% in the broth. The mixture of salts introduced is stirred into the metal mass, an operation that is carried out every half hour or so. It is tried to maintain the temperature of the broth within the aforementioned range, and during the times of 1 h, 3 h and 6 h, it will be possible to strain said material in the molds to the effect, sand or mold, keeping the piece the modified structure and keeping the mechanical characteristics similar to those obtained with the modification made with sodium. The temperature of the broth can rise up to 825º C and after two hours of effecting the addition of the Sr it can be cast and the piece will retain the modified structure.
