Development of microstructural heterogeneities and dynamic restoration activity during ring rolling of Ti-6Al-4V alloy and its tensile response

Numerical Simulation as a Tool for the Study, Development, and Optimization of Rolling Processes: A Review

“…In terms of the materials studied, aluminum alloys and steels are the most tested materials, being present in eleven and ten of the articles included in Table 1, respectively. In other studies, simulations of rolling processes have been carried out for titanium [24,34,35,43], copper [32,38], magnesium [28,39,45], and molybdenum [40] alloys and nickel-based superalloys [25,42]. In four papers, clad plates consisting of two different materials [32,35,45,48] have been studied.…”

“…Nayak et al [34] studied the effect of feed rate on the development of heterogeneities during hot rolling of Ti-6Al-4V alloy rings using FEM simulations. The research was carried out for rings with initial and target diameters of 150 and 170 mm rolled at 880 °C.…”

“…From the results predicted by simulation, it was determined that under the rolling stability condition, the ring cross section and outer radius met the design requirements, and the central displacement and roundness errors of the ring were reduced by 75%. As can be seen in Table 6, the papers discussed in the present section address the numerical simulation of different aluminum alloys [23,26,50], titanium [24,34], steels [42,44], and nickel-based superalloys [25]. Hot rolling conditions have been used in all the cases, with temperatures ranging from 420 to 1200 °C depending on the material used.…”
