Summary:in order to per-form in situ temperature and bending measurements during heterogeneous heating of a tube in a laboratory furnace. It has been evident that the thermal gradients and the austenitization of the steel induces complex bending variations during heating. In addition, a model that couples radiative heat transfers in the furnace with heat transfer, phase transformations, stresses and deformations in the part has been built by coupling computer codes Fluent and Sysweld. The simulated results allow us to predict the bending evolution during heating and to highlight the respective effects of the temperature evolutions and the kinetics of phase transformations in the different regions of the tube. It is also shown that the simulated results agree rather well with the experimental results.
