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. ...

Abstract In this work, a support vector machine (SVM) model was developed to predict the hot deformation flow curves of AZ91 magnesium alloy. The experimental stress-strain curves, obtained from hot compression testing at different deformation conditions, were sampled. Consequently, a data base with the input variables of the deformation temperature, strain rate and strain and the output variab...

In this work, magnesium-based composites were obtained by shock-wave compaction of a powder mixture Mg-5 wt.% AlN at pressure 2 GPa. Their microstructure was investigated and the phase composition determined, from which it follows that nanoparticles retain their are uniformly distributed in magnesium matrix. The materials used as master alloys for production die casting. amount aluminum nitride...

The effect of solution-treated on the self-corrosion performance and discharge AZ91 magnesium alloy as anode material was analyzed by microscopic characterization, immersion tests, electrochemical measurements, tests. study shows that β-phase in gradually dissolved matrix with increase solution temperature, activity significantly improved. Through comparison three different processes, it is fou...
