Prediction of Ring Rolling Process of PM Ti₂AlNb Alloy by Hot Isostatic Pressing Based on Gleeble-3800 and FE Simulation

Abstract:

Hot workability during hot ring rolling of Ti₂AlNb alloy prepared by hot isostatic pressing (HIPing) was studied in this work. Compression results showed that the hot workability of HIP’ed Ti₂AlNb was comparable to that of wrought Ti₂AlNb. O phase disappeared in compression samples (conducted from 930~1030°C, ~50% total reduction) after deformation which is considered to cause elongation decrease. Finite element method (FEM) was used to predict the temperature/strain distribution during rolling process, and the results indicated that the rolling parameters were very crucial. A sound hot ring rolled billet was successfully fabricated based on an optimized rolling process. Thermal mechanical simulation and FEM are very useful tools for parameters selection during ring rolling.
