Based on the KRC model as transformation thermodynamics, a new model of the phase equilibrium temperature of X80 pipeline steel has been established by C++ under the hot deformation conditions, on which analyzing the influences of true strain, deformed temperature and strain rate. The results given by the model have good agreements with the measured value. It shows that the model can have a good accuracy...
Deformation resistance of X80 pipeline steel was researched by experiment with the Gleeble-3500. Establishing the model of dislocation density of X80 pipeline steel through the corresponding relationship between dislocation density and deformation resistance, then combining with the thermodynamic model of X80 pipeline steel which is based on the KRC thermodynamics model in order to analysis the effect...
