EFFECT OF THE INCLINED COOLING PLATE CHARACTERISTICS ON THE THIXOTROPIC MICROSTRUCTURE OF A356.0 ALUMINUM ALLOY
In the present work microstructural evolution of A356 Aluminum alloy using an inclined cooling plate casting process for thixoforming feedstock production is investigated. The resultant microstructure was evaluated and compared with those of the same alloy produced by the conventional casting process, i.e. directly cast in the same mold without using an inclined cooling plate. It was found that...
متن کاملOptimization and utilization of semisolid casting process for semisolid welding of Al-6061 alloy
Semisolid processing is one of the modern routes in sound and near net shape parts production. Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...
متن کاملTensile and fatigue behavior of AZ91D magnesium alloy
Recently magnesium alloys, owing to their low density and excellent specific strength have been attractive to designers as an advanced material for coping with energy conservation and environmental pollution regulations. Much of the recent developments of magnesium alloys and processes have been driven by the requirements of the aerospace industry, although some successful ones have found appli...
متن کاملInfluence of Zeolite Coating on the Corrosion Resistance of AZ91D Magnesium Alloy
The protective performance of zeolite coating on AZ91D magnesium alloy was evaluated using potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) in 0.1 M sodium chloride solution (NaCl). Electrical equivalent circuit (EEC) was developed based upon hypothetical corrosion mechanisms and simulated to correspond to the experimental data. The morphology and the chemical natur...
متن کاملEffect of heat treatment on corrosion and electrochemical behaviour of AZ91D magnesium alloy
An AZ91D ingot in the as-cast condition was homogenized by solution treatment and then aged for various periods of time. The microstructures produced were studied in detail and the b phase volume fraction was measured quantitatively. The Corrosion resistance of all the different microstructures was studied in 3.5% NaCl solution through weight loss measurement in constant immersion conditions an...
