The in ̄uence of chloride ion concentration and pH on the corrosion and electrochemical behaviour of die-cast and ingot-cast AZ91D alloy have been studied with a focus on the stability of microconstituents in these environments. The experimental techniques used include immersion studies, potentiodynamic polarization, X-ray di€raction and optical and scanning electron microscopy. The corrosion ra...

Herein, a NiCrAl coating was prepared on the AZ91D magnesium alloy by cold spraying technology. The microstructure, wear resistance, and corrosion resistance of sprayed were studied compared with two coatings plasma spraying. results showed that porosity two-plasma 3.21% 2.66%, respectively, while only 0.68%. hardness (650 HV0.1) higher than those (300 HV0.1, 400 HV0.1). In abrasion test, lower...

AZ91D magnesium alloy rolled under four rolling conditions, namely cold rolling, electric pulse hot and the first principles calculation of Mg with or without external field carried out. The results show that: application current in process can effectively improve edge crack sample, optimize texture reduce its strength, promote generation tensile twins transition from small Angle grain boundari...

The present study evaluates the effect of high-intensity ultrasound (US) in the static and dynamic mechanical behavior of AZ91D by microstructural modification. The characterization of samples revealed that US treatment promoted the refinement of dendrite cell size, reduced the thickness, and changed the β-Mg17Al12 intermetallic phase to a globular shape, promoted its uniform distribution along...
