“…This parameter can be used to comprehensively characterize the effect of the deformation process on the material properties. According to previous studies [ 32 , 33 ], the RSR process achieves a high value of effective strain on the rod surface due to the severe shear deformations. In this case, a characteristic gradient distribution of strain across the radius of the rod can be seen.…”

Effect of Radial-Shear Rolling on the Structure and Hardening of an Al–8%Zn–3.3%Mg–0.8%Ca–1.1%Fe Alloy Manufactured by Electromagnetic Casting

Aluminum alloys are one of the most common structural materials. To improve the mechanical properties, an alloy of the Al–Zn–Mg–Ca–Fe system was proposed. In this alloy, when Fe and Ca are added, compact particles of the Al10CaFe2 compound are formed, which significantly reduces the negative effect of Fe on the mechanical properties. Because of the high solidification rate (about 600 K/s) during cylindrical ingot (~33 mm) production, the electromagnetic casting method (ECM) makes it possible to obtain a highly dispersed structure in the cast state. The size of the dendritic cell is ~7 μm, while the entire amount of Fe is bound into eutectic inclusions of the Al10CaFe2 phase with an average size of less than 3 μm. In this study, the effect of radial shear rolling (RSR) on the formation of the structure and hardening of the Al–8%Zn–3.3%Mg–0.8%Ca–1.1%Fe alloy obtained by EMC was studied. Computer simulation of the RSR process made it possible to analyze the temperature and stress–strain state of the alloy and to select the optimal rolling modes. It was shown that the flow features during RSR and the severe shear strains near the surface of the rod (10 mm) provided a refining and decrease in the size of the initial Fe-containing particles.

“…With the development of computer programs for simulation, the use of the finite element method (FEM) is an available solution to this problem. Software systems for the simulation of metal-forming processes allow engineering analysis of the main process parameters to be performed without significant time and financial costs [ 19 , 20 , 21 , 22 , 23 , 24 ].…”

The comprehensive analysis of temperature influence on the strain–speed parameters of radial-shear rolling of Al-Zn-Mg-Ni-Fe alloy including the investigation of rheological properties, FEM simulation, and in-depth analytical interpretation of results was carried out. The rolling temperature has significant effect on the kinematic of metal forming, speed parameters, configuration, and length of trajectories. With the decrease in temperature, the speed of metal movement reduces, and this is the same for different components. The greatest decrease is noted for the axial speed component. In general, according to the nature of effect on the strain kinematic state, a temperature reduction of 100 °C (from 500 to 400 °C) acts similarly to a decrease in feed angle of about 4° and, in particular, increases the rolling time, nonuniformity of deformation, tightening, and temperature effect of deformation heating.

“…Despite the high number of carried out experimental works, assessing the influence of technological factors on the metal sliding in the deformation zone and the wear of the mandrels during screw rolling is still hard. The finite element method is frequently used in numerical modeling to solve complex temperature-deformation problems during hot metal forming [12,13]. Many studies, for example, have used finite element simulation to study the wear of working tools of pipe-produced mills, such as a continuous rolling mill [8][9][10] and piercing mill of screw rolling [14].…”

This paper aims to use the QFORM software package based on the finite element method with a view to computer modeling the wear process of rolled mandrels of the screw rolling mill MISIS - 130D while rolling stainless steel X12CrNiTi18-9 billets into pipes. The wear properties of the mandrels change as the plugging process occurred under various initial conditions. The results show that the wear rate on the mandrels in the reduction zone is more intense at a higher feed angle and distance between guide shoes. Wear distribution on mandrels surfaces can be improved by adjusting the velocity along the rolling side of the mandrels and replacing them with long fast-moving long mandrels. The simulation which results in this work can be used to predict the properties of working-tool wear, depending on the technical parameters, and rolling mode, which consequently increases the quality of rolling process fabrication products and the service life of tools.
