20.500.12556/RUL-136703 Transformation of the metastable Al$_6$Fe intermetallic phase during homogenization of a binary Al-Fe alloy Within the scope of this research the transformation of the Al$_6$Fe metastable phase was analyzed via Differential Scanning Calorimetry (DSC), optical and Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). A binary Al-Fe1.1 low-impurity alloy was produced with refined raw materials in a controlled environment. With a cooling rate of 35 K/s, solidification of the Al$_6$Fe metastable phase was achieved. The samples were homogenized at 600 °C for 2–24 h. Results of a qualitative analysis of metallographic samples show that the transformation began on grain boundaries, forming an Fe-phase free region, but after 2 h began to take place within the eutectic region. The transformation is mostly complete after 12 h, but after 24 h of homogenization it is fully complete as all samples, except the 24 h homogenized one, contain both the metastable Al$_6$Fe and the stable Al$_{13}$Fe$_4$ phase. homogenization aluminum alloys phase transformation differential scanning calorimetry true false true Angleški jezik Ni določen Članek v reviji 2022-05-17 08:18:58 2022-05-17 08:18:59 2022-09-15 04:14:12 0000-00-00 00:00:00 2021 0 0 9 str. iss. 23, art. 7208 Vol. 14 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669 1996-1944 10.3390/ma14237208 86912003 materials-14-07208.pdf materials-14-07208.pdf 1 D610006CF9678973E265E27EBCDE4B87 ebfd80035828f214793bbe1997f722fb9f9e6b883f75d79930c8b416170dd7e2 700a9a84-d5a9-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156454 https://www.mdpi.com/1996-1944/14/23/7208 0 32e72b89-d5a9-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156453 Naravoslovnotehniška fakulteta 0 0 0
