“…From the stimulation of the TSCT, Fereshteh-Saniee et al conducted friction tests on AZ31 and AZ80 alloys in this test for hot plastic working of magnesium alloys. They reported that the experimental and simulation results agreed [12]. In addition, TSCT and ring compression tests were conducted to evaluate the friction of Dry, MoS2, and CASP during hot working.…”

Abstract. 7000 series aluminum alloys are high-strength alloys used in various lightweight products in the transportation equipment and aerospace industries. AA7075 extrusions are expected to find further applications in multiple fields, including aircraft parts, automotive parts, and sporting goods. However, the high deformation resistance and surface cracking defects caused by tool galling and adhesion have resulted in extremely low productivity. In this study, the V-groove compression test was proposed as a method to determine the coefficient of friction in hot metal forming. Using AA7075 as the experimental material, what did the V-groove compression test at various temperatures to compare the results with calibration curves created from the numerical analysis and observe the growth of adhesion.

“…Meanwhile, the finite element method (FEM) [17,18] combined with experiments is widely used to analyze the deformation behaviors during forming. Fereshteh-Saniee et al [19,20] conducted experimental and numerical studies on several magnesium alloys such as AZ31 and AZ80 and found that the friction sensitivity of the T-shape experiment increased with decreasing die edge radius, increasing test temperature and strain rate. FEM predictions then showed that the simulation curve matched well with the experimental load curve.…”

“…However, the above-mentioned method is limited to traditional tension and compression deformation. Fereshte-Saniee et al [19] showed the microstructures of the cast AZ80 alloy during T-shape deformation and found that the grains were uniformly elongated at the edge radius of the grooved die, while the grains in the middle part were less sensitive to the friction and kept its initial uneven structure.…”

Ultrafine-grained (UFG) materials can effectively solve the problem of size effects and improve the mechanical properties due to its ultra-high strength. This paper is dedicated to analyzing the deformation behavior and microstructural evolution of UFG pure copper based on T-shape upsetting test. Experimental results demonstrate that: the edge radius and V-groove angle have significant effects on the rib height and aspect ratio λ during T-shape upsetting; while the surface roughness has little effect on the forming load in the first stage, but in the second stage the influence becomes significant. The dynamic recrystallization temperature of UFG pure copper is between 200 °C and 250 °C.

“…Due to the difficulty of characterising the contact in a real process, many studies have approached the problem using laboratory tests. For this purpose, test methods such as upsetting-sliding [4,5], T-shape compression [6], Pin-on-disc [7] or the widespread ring compression [8,9] have been used. However, Joun et al [8] concluded that the friction evaluation curves achieved by means of the ring compression test were irrelevant for the hot rolling process that they analysed.…”

This paper studies the influence of diverse friction models on the numerical analysis of an industrial skew rolling mill using FORGE®. The originality of the present contribution is the analysis of the effect of the friction model on important parameters, namely, consumed power, plastic deformation and surface temperature. The aim is to evaluate which of these friction models is appropriate for simulating these industrial processes. The high values of temperature, pressure and sliding velocity at the contacts make the assessment of the friction model incidence on the deformation and temperature evolution fundamental, given its importance on the thermomechanical processing of materials. As a conclusion, IFUM is not valid because of its sliding velocity approach. On the other hand, Neumaier presents the highest deviations in terms of experimental power. It is concluded that Tresca is valid for this sort of processes and Norton model gives the most accurate results for friction power, related to the high sliding conditions at the contact.
