Transformation of the metastable Al$_6$Fe intermetallic phase during homogenization of a binary Al-Fe alloyArbeiter, Jože (Avtor) Vončina, Maja (Avtor) Šetina, Barbara (Avtor) Medved, Jože (Avtor) homogenizationaluminum alloysphase transformationdifferential scanning calorimetryWithin 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.20212022-05-17 08:18:58Članek v reviji136703UDK: 669ISSN pri članku: 1996-1944DOI: 10.3390/ma14237208COBISS_ID: 86912003sl
