Abstract

The continuous development of innovative materials with improved functional properties is needed to meet the demands of modern transport industry. Given that previous research did not cover aluminum (Al) alloys with combined additions of magnesium (Mg) and lithium (Li), a contemporary approach in design and synthesis of an Al-Mg-Li alloy was applied. The research was performed under the basic assumption that the solidification sequence and microstructure development can be affected by the chemical composition, thermodynamic parameters, and processing parameters. A proper correlation of these parameters should result in an alloy with improved properties in the as-cast condition.

Abstract (croatian)

Potreban je kontinuirani razvoj inovativnih materijala s poboljšanim funkcionalnim svojstvima kako bi se zadovoljili zahtjevi moderne transportne industrije. S obzirom da dosadašnjim istraživanjima nisu obuhvaćene legure aluminija (Al) s kombiniranim dodacima magnezija (Mg) i litija (Li), primijenjen je suvremeni pristup u razvoju i sintezi legure Al-Mg-Li. Istraživanje je provedeno pod osnovnom pretpostavkom da na slijed skrućivanja i razvoj mikrostrukture mogu utjecati kemijski sastav, termodinamički i procesni parametri. Ispravna korelacija ovih parametara trebala bi rezultirati slitinom s poboljšanim svojstvima u lijevanom stanju.
