Abstract:

the one pass compression test of Mid-Ti Contained in Q345B was achieved by using the Gleeble-1500 thermal simulation experiment machine. The true stress-strain curve was studied under the deformation temperature was between 1000 to 1150°C and the strain rate was from 0.01 to 0.3 s-1. And then, based on Sellars model, the function relationships between critical strain (εc), strain rate (ε) and deformation temperature (T) of dynamic recrystallization of the Mid-Ti Contained in Q345B were reached: εc=2.588×10-3Z0.12, Z=εexp (439583/8.314T).
