Structural modification of Al-Al3Fe eutectic alloys

New Strategy to Improve the Mechanical Properties in Cast Al–Mg–Fe Alloys by the Formation of Al–AlFe Eutectic

“…It indices that the precipitation temperature of eutectic Al–Al 13 Fe 4 ( E αβ ) is 641 °C, which is consistent with a previous study. [ 25 ] Then, the possible eutectic Al–Al 6 Fe ( E αγ ) forms at 609 °C. Meanwhile, the precipitation peak of the primary phase cannot be observed, which indicates that very few primary phases are formed in the A1 alloy.…”

Doping and adsorption mechanism of the element Y modifying the primary Al13Fe4phase in hypereutectic Al–Fe alloys from first-principles

“…The primary Al 13 -Fe 4 phase easily forms the (001) and (100) twins along the [010] orientation. Most of the needles, flakes and lath shapes of the Al 13 Fe 4 phase always grow along the [010] orientation, forming a large proportion of the Al 13 Fe 4 phase with the (100), (001), and (−201) faces exposed, parallel to the [010] growth direction, [8][9][10][11] or preferred growth along the [010] and [011] orientations. 12 It is worth noting that the mesoscopic morphology can be determined by surface energy, which plays an important role in crystal growth phenomena.…”
