Abstract:Isothermal constant strain rate compression of Ti2AlNb-based alloys was carried out using a Gleeble-3500 thermal simulation tester with deformation temperatures of 650-850°C, strain rate interval of 0.001–1s-1, on the basis of which a modified Zerilli-Armstrong model and an optimised Zerilli-Armstrong model were developed to describe the thermal deformation behaviour of Ti2AlNb-based alloys. The results show that the error between the predicted and experimental values of the modified Zerilli-Armstrong model is… Show more
