Oxide Film and Porosity Defects in Magnesium Alloy Az91
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...
متن کاملstudy of morphology of oxide film formed on magnesium alloys in casting conditions (az91)
morphology of surface oxide film formed during pouring of molten magnesium alloy has been investigated. due to surface turbulence during casting, the oxide film necessarily makes folded cause in a dry surface to dry surface mode creating a double oxide film with the volume of air that can be encapsulated between folds of the film and this led to make gas bubbles or shrinkage cavities form. thes...
متن کاملDynamics of particle settling and 1 resuspension in viscous liquid films
10 We develop a dynamic model for suspensions of negatively buoyant particles on an incline. 11 Our model includes settling due to gravity and resuspension of particles by shear-induced 12 migration. We consider the case where the particles settle onto the solid substrate and two 13 distinct fronts form – a faster liquid and a slower particle front. The resulting transport 14 equations for the ...
متن کاملThe Effect of Environmental Parameters on the Corrosion Behavior of Simple Shear Extruded AZ91 Magnesium Alloys
In this study, the effects of forming method (extrusion) and environmental factors (solution pH and temperature) on the corrosion performance of AZ91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and salt spray techniques. The polarization test results of the specimens showed that simple sh...
