“…Hence, the existence of direct proportionality of the peak temperature with these parameters has been established. Results presented by Serio et al in their research also support the fact that the thermal behavior of joints is closely connected to the process parameters, which therefore, also strengthens the simulation model presented in the research [15,16]. …”

Abstract:Friction welding is one of the foremost welding processes for similar and dissimilar metals. Previously, the process has been modeled utilizing the rudimentary techniques of constant friction and slip-stick friction. The motivation behind this article is to present a new characteristic for temperature profile estimation in modeling of the rotary friction welding process. For the first time, a unified model has been exhibited, with an implementation of the phase transformation of similar and dissimilar materials. The model was generated on COMSOL Multiphysics ® and thermal and structural modules were used to plot the temperature curve. The curve for the welding of dissimilar metals using the model was generated, compared and analyzed with that of practical curves already acquired through experimentation available in the literature, and then the effect of varying the parameters on the welding of similar metals was also studied.

“…Moreover, some researchers [45][46][47] were focused on the thermography method which has been defined as a modern method for investigating the thermal field through online monitoring of the process, inspection and research. It should be mentioned that, this method is mainly used to determine the thermal field variations, when the measurements are difficult or impossible to record (i.e., inside the weld).…”

Friction Stir Welding (FSW) is a novel kind of welding for joining metals that are impossible or difficult to weld by conventional methods. Three-dimensional nature of FSW makes the experimental investigation more complex. Moreover, experimental observations are often costly and time consuming, and usually there is an inaccuracy in measuring the data during experimental tests. Thus, Finite Element Methods (FEMs) has been employed to overcome the complexity, to increase the accuracy and also to reduce costs. It should be noted that, due to the presence of large deformations of the material during FSW, strong distortions of mesh might be happened in the numerical simulation. Therefore, one of the most significant considerations during the process simulation is the selection of the best numerical approach. It must be mentioned that; the numerical approach selection determines the relationship between the finite grid (mesh) and deforming continuum of computing zones. Also, numerical approach determines the ability of the model to overcome large distortions of mesh and provides an accurate resolution of boundaries and interfaces. There are different descriptions for the algorithms of continuum mechanics include Lagrangian and Eulerian. Moreover, by combining the above-mentioned methods, an Arbitrary Lagrangian-Eulerian (ALE) approach is proposed. In this paper, a comparison between different numerical approaches for thermal analysis of FSW at both local and global scales is reviewed and the applications of each method in the FSW process is discussed in detail. Observations showed that, Lagrangian method is usually used for modelling thermal behavior in the whole structure area, while Eulerian approach is seldom employed for modelling of the thermal behavior, and it is usually employed for modelling the material flow. Additionally, for modelling of the heat affected zone, ALE approach is found to be as an appropriate approach. Finally, several significant challenges and subjects remain to be addressed about FSW thermal analysis and opportunities for the future work are proposed.

Accumulative roll bonding (ARB) technique is used in this paper to produce aluminum/alumina composite sheets. Alumina content was added as 1,3 and 5wt%. The produced Al/Al 2 O 3 composite sheets are piled up and processed by accumulative roll bonding (50% reduction) after preheating at 280°C with different regimes (2-8 cycles). Statistical design analysis was applied to examine the effects of alumina content and no. of accumulative roll bonding cycles on the ultimate tensile strength for aluminum/alumina composite sheets. Empirical formulas were deduced to recognize key parameters that controlling tensile behavior. XRD detection was carried out to explore dominant planes controlling plasticity Al/Al 2 O 3 composites. In general, addition of alumina and proceeding different cycles increases strength. FE-SEM microstructure showed that alumina plays important roll on the aluminum sheets during ARB process where the metal of aluminum flow among them producing highly sheared matrix.
