Ratcheting crystal plasticity modeling in microstructure of magnesium alloy under stress-controlled cyclic tensile loading with non-zero mean stress
Todays, the requirement of lowering the vehicle weight for the reduction of the fuel consumption and emissions, one of the methods considered by designers is to use the ligh magnesium alloy under cylclic loadings. In this article, considering the microstructure of the AZ91D magnesium alloy, its crystalline structure, a model for predicting the ratcheting behavior of this alloy was adapted and v...
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 کاملGrain Boundary Sliding in Ice
It is well known that grain boundary processes intercrystdline sliding and grain boundary migration make an important contribution to high temperature deformation of polycrystalline materials, particularly for metals. More recently, these processes have been correlated with the atomic structure of the boundaries. Our goal is to study sliding and migration of ice boundaries, with respect to temp...
متن کاملPrediction of corrosion rate of AZ31B magnesium alloy under salt fog environment in NaCl solution
Magnesium alloys have gained considerable interest as a material for automotive and aerospace applications due to its low density, high specific strength, and good castability. However, another considerable issue is their corrosion properties. This restricts their practical applications. In this present research, corrosion behavior of the AZ31B magnesium alloy was evaluated by conducting salt f...
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 ...
