Opis:: The gas-tungsten arc (GTA) welding behaviors of the commercial AZ91 magnesium alloy were examined in terms of microstructure characteristics. This study focused on the effects of the GTAW process parameters (like welding current, welding speed and method of additional cooling of the welded samples) on the size of the fusion zone (FZ) and partially melted zone (PMZ). The PMZ morphology of the eutectic regions changed from less to more divorced in the direction from the FZ to the base metal. The largest PMZ was obtained at a low welding speed (3.33 mm/s) and without additional water cooling of the samples.

Opis:: Microstructural analysis of as-cast Mg-9Al-0.9Zn-xRE (x = 0, 1, 2, 3, 5 wt.%) magnesium alloys is presented. Light microscopy (LM) and scanning electron microscopy (SEM+EDX) were used to characterized the obtained material. The results revealed that the as-cast AZ91 alloy consists of α – Mg matrix, binary eutectic α + γ (where γ is Mg17Al12). While rare earth elements were introduced to the Mg-Al-Zn alloy new Al11RE3 phase was formed. Additionally, in the experimental alloys instead of Al-Mn phase, ternary Al-Mn-RE compound was observed. What is more, the influence of RE addition on the area fraction of eutectic and needle-like phase was analysed. With increasing addition of RE, the amount of γ phase decreased, but the amount of Al11RE3 phase increased.
