Constitutive Modelling of AZ31B-O Magnesium Alloy for Cryogenic Machining
The success of a FE model for metal cutting process is strongly dependent on the accurate characterization of the workpiece material, under similar conditions as those found in metal cutting. In this paper, dynamic shear tests using a Gleeble machine have been performed on 4 mm thickness disks of AZ31B-O magnesium alloy, using a special designed tool. In order to include the effects of the cryo...
متن کاملMechanical Behavior of AZ31B Mg Alloy Sheets under Monotonic and Cyclic Loadings at Room and Moderately Elevated Temperatures
Large-strain monotonic and cyclic loading tests of AZ31B magnesium alloy sheets were performed with a newly developed testing system, at different temperatures, ranging from room temperature to 250 °C. Behaviors showing significant twinning during initial in-plane compression and untwinning in subsequent tension at and slightly above room temperature were recorded. Strong yielding asymmetry and...
متن کاملEffect of KOH concentration on the microstructure and electrochemical behavior of ceramic coatings formed by plasma electrolytic oxidation method on AZ31B Mg alloy
In this study, ceramic coatings were prepared on AZ31B Mg alloy by plasma electrolytic oxidation technique in electrolytes containing sodium fluoride (KF), sodium silicate (Na2SiO3.5H2O) and different potassium hydroxide (KOH) concentrations. The electrochemical behavior of AZ31B alloy and plasma electrolytic oxidation coatings was studied by potentiodynamic polarization, electrochemical impeda...
متن کاملProcess Mechanics and Surface Integrity Induced by Dry and Cryogenic Machining of AZ31B-O Magnesium Alloy
The corrosion resistance of magnesium alloys depends mainly on its surface integrity. Previous experimental studies have shown that machining can induces small (nano-scale) grain size, compressive residual stresses and basal plane crystallographic texture, which significantly improve the corrosion resistance of magnesium alloy. These studies have focused on the positive effects of cryogenic coo...
متن کاملOptimizing the Process Parameters of Friction Stir Welded Joint of Magnesium Alloy Az31b
This paper deals with Friction stir welding of AZ31B Mg alloy by using H13 Tool at different rotational speeds and welding speeds .Experiments were conducted according to L4 Orthogonal array which was suggested by Taguchi. Optimum parameters for optimum Tensile strength, Hardness and Ductility were found with the help of S/N ratios. Therefore optimization of input process parameter is required ...
