“…The segregation phase is observed at grain boundaries, and the segregation phase is Al 6 (FeMnSi) compound. The Fe compound is the main impurity of Al alloy, which will greatly decrease the toughness, plasticity, thermal fatigue strength, and it is adverse for downstream process [14,15].…”

“…The Zr content in the alloy is only 0.17 wt.%, but as Al 3 Zr compound forms already in the liquid as primary phase [8,10], the concentration of Zr in the solid solution is lower. Furthermore, as this solid solution forms by peritectic reaction from the liquid containing 0.11 wt.% Zr and Al 3 Zr [3] and since Zr diffuses slowly, zirconium is very heterogeneously distributed, preferentially in the center of the solidification cells or dendrites [12].…”

“…4c). The coherent particles were identified by electron diffraction as the Al 3 Zr phase, non-coherent particles are supposed to be α-Al(Mn,Fe)Si dispersoids [6][7][8]. The sheet deformed 96% shows the most important increase in the electrical conductivity in the first stage (Fig.…”

“…Silicon addition favours the formation of Al(Mn,Fe)Si phases [3]. In alloys containing excess amount of Si over Fe, only a mixture of cubic α-Al 12 (Mn,Fe) 3 Si and hexagonal α-Al 15 (Mn,Fe) 3 Si 2 phases was found [6][7][8]. Even after proper processing to obtain a fine dispersion of α-Al(Mn,Fe)Si particles, the recrystallization resistance of Al-Mn alloys is often insufficient and other additives are necessary.…”

“…The paper reviews main results of the studies of the inuence of Si and Fe on the size and formation of dispersoids and recrystallization behaviour of AlMnZr alloys prepared by direct-chill (DC) casting in the laboratory conditions [13] and also by twin-roll casting (TRC) in the industrial conditions [14]. 2.…”

AlMn alloys are often used for the production of automotive heat exchanger ns. During brazing at about 600• C, recrystallization and grain coarsening resulting in the reduction of the strength and possible buckling of the n can occur. In order to obtain a good recrystallization resistance, the alloy should contain a dense and homogeneous distribution of second phase particles. The eect of Si and Fe addition on the recrystallization response of AlMnZr alloys direct-chill cast in the laboratory conditions and twin-roll cast in the industrial conditions was examined. Microstructure of the alloys was characterized during downstream processing. The particles were analyzed by light metallography, energy dispersive X-ray spectroscopy and by means of electron backscattering diraction. Computer assisted quantitative particle analysis was carried out on eld emission gunscanning electron microscope micrographs. Vickers hardness and electrical conductivity were measured at thicker sheets, while at the nal gauge of 65 µm the 0.2% proof stress was evaluated. The best recrystallization resistance had twin-roll cast alloy containing 0.5 wt% Si and 0.2 wt% Fe.
