Process 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 کاملConstitutive 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 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 ...
متن کاملAnalysis of Surface Roughness and Material Removal Rate in Dry and Cryogenic Machining of En31 Steel
Production rates play important role in the turnover of any industry. In order to increase the production rates, industrial processes are need to be speedup by speeding input parameters such as cutting speeds, feed rates etc. But with the higher speeds and feeds the heat generation also increases between tool-chip, tool and work piece interfaces, which reduce the tool life, product quality and ...
متن کاملExperimental Evaluation of Surface Alterations Induced in Machining of Ti-6Al-4V Alloy
Surface integrity of workpieces after machining processes is one of the most essential requirements of engineers in advanced industries, since it has significant effect on performance and service life of the components. Based on this, thermal and mechanical loads generated by machining are responsible for change in mechanical properties of the machined workpiece and consequently, they should be...
