Abstract
U radu je analizirana kolika je mogućnost sanacije oštećenja aluminijskih odljevaka pri čemu se vršilo ispitivanje na tlačno lijevanom AlSi9Cu3(Fe). Prema dosadašnjim mjerenjima u primjeni se pokazalo da aluminij iako prema svojim svojstvima je jako dobar materijal je podložan oštećenjima koja ponekad izazivaju jako velike posljedice. Zadatkom se trebalo analizirati kako možemo utjecati da ne bi došlo do tih oštećenja aluminijskih odljevaka, tj. kakve su sanacije potrebne. Teorijska analiza je pokazala kemijski sastav AlSi9Cu3(Fe) te kako su vršena ispitivanja na uzorcima s različitim presjecima, ali istim šaržama. Eksperimentalnim putem je utvrđeno da su aluminijski odljevci jako brzo pucali i pri relativno malim silama. Što je bio veći promjer to je odljevak brže pucao, a to može biti posljedica lošeg zavara kao što je pojava uključaka, mjehurića. Rezultati analize pokazuju da nakon kratkotrajnog zagrijavanja legure AlSi9Cu(Fe) dolazi do izvjesnih promjena mehaničkih svojstava. Porast temperature utječe na vlačnu čvrstoću, ali ne i na istezljivost. Putem provedenih rezultati možemo doći do zaključka da treba nastaviti istraživanja ovisnosti mehaničkih svojstava odljevaka te obaviti jednim od postupaka pravilnu sanaciju oštećenja.
Abstract (english)
The paper analyzes the possibility of repairing the damage of aluminum castings by testing the pressure-molded AlSi9Cu3 (Fe). According to the previous measurements in the application it has been shown that aluminum, despite its very good material properties, is subject to damages which sometimes have very serious consequences. The task should be to analyze how we can influence the damage of aluminum castings, that is, what remedies are needed. The theoretical analysis showed the chemical composition AlSi9Cu3 (Fe) and samples were tested on different slices, but with the same batches. Experimentally, it was found that aluminum castings were very quick to shoot at relatively low forces. The larger the diameter the casting was, the faster the shot, and this could be the result of bad confusion as the incidence of bubbles. The results of the analysis show that after a short period of heating of the AlSi9Cu (Fe) alloy there are some changes in mechanical properties. Temperature increase affects tensile strength, but not elasticity. Through the results we can conclude that we should continue to investigate the dependence of the mechanical properties of the castings and do one of the procedures for proper repair of the damage.
