摘要：

In this paper, the hot deformation behavior of Ti2AlNb-based alloy was studied by Gleeble-3500 thermal simulation experiment machine under deformation temperatures of 650-850°C and strain rates of 0.001-1 s-1, and the optimal deformation process parameters range of Ti2AlNb-based alloy was obtained by response surface method. First, the flow stress curves of Ti2AlNb-based alloy under different deformation conditions were analyzed, and the hot deformation activation energy Q, InZ and power dissipation factor η were calculated, so as to establish the second order response surface model for the thermal deformation activation energy Q, InZ and power dissipation factor η, and the optimal process parameters region optimization was obtained through multi-objective visual optimization, which was verified by the microstructure. The results show that the flow stress of Ti2AlNb-based alloy decreases with the increasing in deformation temperature and the decreasing in strain rate. The established response surface models have high accuracy, which can be used for optimization and analysis of process parameters. The result of multi-objective visual optimization show that the optimal process parameters region for Ti2AlNb-based alloy is 750-850°C and the strain rate of 0.005-0.03 s-1. © 2023 Rare Metals Materials and Engineering Press.
