WebNov 30, 2024 · In order to obtain the kinetics of DRX for specific points in the workpiece during hot rolling, the Beynon–Sellars model for DRX without grain size dependency has been implemented via a USDFLD subroutine. The kinetic of dynamic recrystallization \(X_{DRX}\) is given in Eq. WebIt was revealed experimentally that hot rolling with a higher strain is efficient for obtaining the initial microstructure, which has equiaxed fine grains of β-NbTi with the aid of …
