Abstract
Ovaj rad podijeljen je na dva dijela, teorijski dio i eksperimentalni. U okviru teorijskog dijela rada, proučene su Al-Si legure, s naglaskom na AlSi7Mg leguru, njezina svojstva i primjenu. Također, obuhvaćene su tehnologije lijevanja aluminijevih legura te je detaljnije objašnjena obrada taljevine. U eksperimentalnom dijelu provedena je obrada taline AlSi7Mg legure. Napravljeno je usitnjavanje zrna pomoću Nukleanta 100 SP i modifikacija eutektika pomoću Simodala 77. Lijevani su odljevci za statički vlačni pokus i ispitivanje kemijskog sastava bazne i obrađene taline. Također je provedena toplinska analiza i snimljene su krivulje hlađenja. Napravljena je metalografska analiza mikrostrukture. Toplinska analiza pokazala je učinak sredstva za usitnjavanje zrna. Metalografija je pokazala učinak modifikacije eutektika. Očekivani utjecaj obrade taline na mehanička svojstva nije dobiven.
Abstract (english)
This paper is divided into two parts, the theoretical part and the experimental part. Within the theoretical part of the paper, Al-Si alloys were studied, with emphasis on AlSi7Mg alloy, its properties and applications. Also, the technologies of aluminum alloys casting are included and the melting process with melt treatment is explained in more detail. In the experimental part, the AlSi7Mg alloy melt treatment was processed. Grain refinement was performed using Nucleant 100 SP and eutectic modification using Simodal 77. Samples were cast for tensile testing and testing of the chemical composition of the base and treated melt. Thermal analysis was also performed and cooling curves were recorded. A metallographic analysis of the microstructure was performed. Thermal analysis showed the effect of grain refining agent. Metallography showed the effect of eutectic modification. The expected influence of melt treatment on mechanical properties was not obtained.
