Tensile 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 Milling Conditions on the Surface Quality in High-Speed Milling of Titanium Alloy
The study was focused on the machined surface quality of titanium alloy under different milling conditions, including milling speed, tool rake angle and cooling method. The surface quality was investigated in terms of residual stress and surface roughness. The results show that the compressive residual stresses are generated on the machined surface under all milling conditions. The compressive ...
متن کاملIn Situ Formation and Refinement of Mg2Si in Fiber-Reinforced AZ91D Magnesium Alloy*
In order to obtain a lightweight material having an excellent high-temperature strength, Mg alloy composites reinforced with short alumina fibers and in situ Mg2Si particles were fabricated. The composites were fabricated by pressureless infiltration of the Mg alloy melt into the preform consisting of the fibers and attached Si particles. The volume fraction of Si particles in the preform, the ...
متن کاملHot cracking in tungsten inert gas welding of magnesium alloy AZ91D
Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...
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...
