In the current research, corrosion behaviors of AZ91 Mg-hybrid composites amalgamated with titanium carbide and alumina reinforcing particles have been investigated. developed by using bottom pouring vacuum-based stir casting process to attain homogeneous distribution in AZ91-Mg matrix. The behavior AZ91-hybrid has evaluated potential (OCP) dynamic polarization scans, as well friction coefficie...

Magnesium alloys are commonly melted and held in steel or cast iron crucibles small but important amounts of Fe C can dissolve into Mg-rich melts. Here, carbide formation is studied during interface reactions between solid Fe-xC (x = 0–3.6 wt%) liquid Mg-9Al-0.7Zn-0.2Mn (wt.%, AZ91) at temperatures from 700 to 800 °C. Two ternary carbides, AlFe3C Al2MgC2, formed the reaction layers Fe-C AZ91, T...

The hydrolysis of Mg-based materials appears to be an ideal solution for clean energy production. Green hydrogen was produced by the reaction a “standard” AZ91 alloy (called in following) “model” seawater solution. Two milling speeds (i.e. 250 rpm and 350 rpm) were tested enhance reactivity AZ91. Graphite AlCl3 used as ball additives. Milling at higher rotational speed is more energetic, hence ...

Effects of different amounts of lead (Pb) and tin (Sn) on microstructure and tensile properties of the AZ91 alloy were studied. The results presented that the microstructure of AZ91 alloy is consisted the α-Mg phase and semi-continuous network of β-Mg17Al12 intermetallics. For the as-cast AZ91 alloy, the average grain siz and the β phase volume fraction were 96.2 µm and of 25.3%, respectively. ...

Porosity is a major concern in the production of light metal parts. This work aims to identify some of the mechanisms of microporosity formation in magnesium alloy AZ91. Microstructure analysis was performed on several samples obtained from gravity-poured ingots in graphite plate molds. Temperature data during cooling was acquired with type K thermocouples at 60 Hz at three locations of each ca...
