20.500.12556/DiRROS-18624 Life cycle assessment of metal alloys for structural applications The study compared environmental footprints of two types of Al-alloys: well-known 5083 aluminium alloy with magnesium and traces of manganese and chromium in its composition. This material is highly resistant to seawater corrosion and the influence of industrial chemicals. Furthermore, it retains exceptional strength after welding. The comparisons were made to an innovative alloy where the aluminium based matrix is reinforced by metastable quasicrystals (QC), thus avoiding magnesium in its composition. Furthermore, we checked other aluminium ingots' footprints and compared European average and Germany country specific production data. Environmental footprints were assessed via cradle to gate life cycle assessment. Our findings normalized to 1 m2 plate suggest, that newly proposed alloy could save around 50 % in value of parameters abiotic resources depletion of fossil fuels, acidification, eutrophication, global warming potential and photochemical ozone creation potential if we compare Qc5 to 6 mm 5083 alloy plate. Only abiotic resources depletion of elements and ozone depletion parameters increase for Qc5 compared to 6 mm 5083 alloy plate. environmental footprints LCA Al-alloys okoljski odtis LCA aluminijeve zlitine true false true IOP Publishing Angleški jezik Slovenski jezik © authors, 2018 Neznano 2024-04-05 08:44:19 2024-04-05 08:55:40 2024-04-09 03:40:10 0000-00-00 00:00:00 2018 0 0 Nasl. z nasl. zaslona; Opis vira z dne 30. 3. 2018; 012003; str. 1-8 Vol. 329 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2018-03-01 62 1757-899X 10.1088/1757-899X/329/1/012003 2357095 2356839 http://dx.doi.org/10.1088/1757-899X/329/1/012003 0 90580e7e-f30f-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25419 RAZ_Malovrh_Rebec_Katja_2018.pdf RAZ_Malovrh_Rebec_Katja_2018.pdf 1 0204E63F994135DF35514949DE70120A 512de6b08b870922ff1c2ec2b2c29f457bbb453f30006cf7b01262fdd9b4e78e 73d3eeeb-f310-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25423 Zavod za gradbeništvo Slovenije 0 0 0
