Rheo-Cast Microstructure and Mechanical Properties of AM60 Alloy Produced by Self-Inoculation Rheo-Diecasting Process
Rheo-forming is becoming the choice for production of high quality parts with diminished defects and fine integrity. In this paper, the novel self-inoculation rheo-diecasting (SIRD) process, in which semisolid slurry is produced by mixing two precursory solid and liquid alloys and subsequently pouring them through a multi-stream fluid director, has been proposed. Microstructural characteristics...
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 کاملMacro-Segregation and Microstructural Characteristics in Rheo-Diecasting of a High Strength Al–4.8mass%Si–0.7mass%Mg Alloy
Rheo-diecasting with electro-magnetic stirring has been carried out to investigate macro-segregation and microstructural characteristics of a high strength AlSiMg alloy under various process conditions. The amount of initial heterogeneous nucleation and the degree of temperature uniformity in the slurry are dependent on the superheat of the melt at pouring into the slurry making vessel. The f...
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...
