Abstract
Cu-Al-Mn legure danas se često koriste u biomedicini, elektroindustriji, avioindustriji i dr. kao materijali s prisjetljivosti oblika. U ovom radu istraživane su ternarne Cu-Al-Mn legure, s različitim udjelima aluminija i mangana, u području bogatom bakrom. Legure su pripremljene u elektrolučnoj peći te su zatim uzorci odliveni u cilindrične kalupe promjera 8 mm i duljine 12 mm. Nakon pripreme uzoraka brušenjem i poliranjem, analiza je provedena optičkom mikroskopijom i pretražnom elektronskom mikroskopijom, uz analizu kemijskog sastava energetsko disperzijskom spektroskopijom. Toplinska analiza provedena je na STA DSC/TG uređaju te su određene temperature transformacija u rasponu od 25 °C do 1150 °C. Termodinamički proračun faznog dijagrama proveden je Thermo-Calc programom, na osnovi pripremljene baze termodinamičkih podataka prema optimiziranim literaturnim podacima. Rezultati termodinamičkog proračuna korelirani su s rezultatima ispitivanja mikrostrukture i toplinske analize.
Abstract (english)
Cu-Al-Mn alloys are often used in biomedicine, electro-industry, aerospace, etc., mostly as shape memory alloys. In this paper, Cu-Al-Mn ternary alloys with different content of aluminium and manganese, in the Cu-rich corner were investigated. Alloys were prepared in the electric-arc furnace and then casted in the cylindrical mould with dimensions of diameter 8mm and length 12mm. After grinding and polishing, samples were analyzed by optical microscopy and scanning electron microscopy, equipped by energy dispersive spectroscopy. Thermal analysis was performed by STA DSC/TG and phase transformation temperatures were determined in the interval from 25 °C to 1150 °C. Thermodynamic calculations were performed by Thermo-Calc software, with prepared database according to optimized parameters. Results of the thermodynamic calculations were correlated with results of microstructure analysis and thermal analysis.
