“…When the friction phase is over, the forging phase starts and the pressure drops from P 1 to P 2 , i.e., 1.4 × 10 6 . All the parameters are in accordance with the experimental work carried out by Alves [13]. Table 3.…”

“…A model was initially developed for the welding of similar metals, i.e., Steel, as well as dissimilar metals, i.e., Steel and Aluminum, and later it was used to develop temperature profiles according to the parameters of experiments conducted by Alves [13]. Structural modules were introduced to accommodate contact conditions, while thermal modules were used to define heat flux and phase transformation of the metals.…”

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.

“…9 when comparing the temperature reached between samples 2-5 and 2-6 (1750 and 2300 rpm, at a friction time of 50 s), where temperature decreases due to the high plasticization of the metal, which entails a reduction in the friction coefficient and limits the temperature rise. Besides, as pointed out by Alves et al [57], the drastic rise in the temperature happens during the first 10 s of friction and additional time is not relevant in heat generation.…”

Weldability of aluminum-steel joints has been studied mainly to avoid the formation of IMC. Nowadays, there are two ways to control the effect of FexAly in welding: 1) the elimination of IMCs or 2) the generation of a thin and homogeneous layer of these phases. In this way, the present work explores the first route, manufacturing joints aluminum-steel using solid state welding process. In order to evaluate the effect of the welding parameters, temperature measures were carried out during the process as well as the microstructural evaluation using optical microscopy and SEM. Finally, the welded joints were subject to tensile strength tests to evaluate their mechanical behavior and try to stablish the nature of the interfacial bonding between both metals. The microstructural characterization of the joints does not reveal the formation of IMCs; this is attributed to the low temperature reached during the process, lower than 545 °C. The welded joint failures in the TMAZ, in the low hardness zone, product of the over aging of the precipitates β". The nature of the bonding in the interface is not clear yet, but it is considered that the atomic diffusion trough the interface and adhesive bonding favors the joint.

“…Misirli et al [160] used thermocouples to experimentally measure the Al-304 stainless steel interface temperatures, which they showed to peak after 4 s of frictional contact. Alves et al [7] experimentally determined Al1050-304 stainless steel heating & cooling temperature distributions which enabled them to characterize the interfacial microstructures and relate this to process parameters. Dissimilar material joints exhibit deformation and flash generation in the lower strength material.…”
