Abstract

Postupak za obradu aluminijumske legure koja sadrži magnezijum i silicijum i to 0.5 – 2.5 % težinskih legirajuće mešavine magnezijuma i silicijuma, gde je molarni odnos Mg/Si između 0.70 i 1.25, dodatna količina Si jednaka približno 1/3 količine Fe, Mn i Cr prisutnih u leguri u % težinskih, a ostatak čine aluminijum, neizbežne nečistoće i drugi legirajući agenti: što se legura posle hlađenja podvrgava homogenizaciji, predgrevanju pre izvlačenja, izvlačenju i starenju, pre čemu se starenje odvija na temperaturama između 160 i 220°C, naznačen time, što starenje posle hlađenja izvučenog proizvoda obuhvata prvi korak u kome se izvučeni proizvod zagreva brzinom zagrevanja iznad 30°C/h do temperature između 100 i 170°C i drugi korak u kome se izvučeni proizvod zagreva brzinom zagrevanja između 5 i 50°C/h do krajnje temperature držanja i što je ukupan ciklus starenja izveden u vremenu između 3 i 24 sata. Prijava sadrži još 9 zavisnih patentnih zahteva.Process for processing aluminum alloy containing magnesium and silicon, 0.5 - 2.5% by weight of alloying mixture of magnesium and silicon, where the molar ratio of Mg / Si is between 0.70 and 1.25, additional amount of Si is equal to approximately 1/3 of the amount of Fe, Mn and Cr present in alloy in% by weight, the remainder being aluminum, unavoidable impurities and other alloying agents: which, after cooling, is subjected to homogenization, pre-heating, pre-extraction, extraction and aging, before aging at temperatures between 160 and 220 ° C. , which aging after cooling of the extracted product comprises the first step in which the extracted product is heated at a heating rate above 30 ° C / h to a temperature between 100 and 170 ° C and the second step in which the extracted product is heated at a heating rate between 5 and 50 ° C / h to the final holding temperature and the total aging cycle performed between 3 and 24 hours. The application contains 9 more dependent claims.
