Abstract
This study investigates the recrystallization phenomenon of strain hardening during welding process in austenitic stainless steel (SUS316), and a suitable annealing temperature for finite element method (FEM) simulation was proposed. The electron backscatter diffraction (EBSD) analysis results of a 1-pass weld with prior surface machining proved that the annealing effect can be introduced owing to the recrystallization phenomenon caused by welding thermal cycle. Therefore, it was necessary to introduce a suitable annealing temperature into the FEM simulation to simulate this phenomenon. To establish a propriate annealing temperature, the 20 % and 30 % pre-strained cold-rolled specimens were subjected to peak temperatures ranging from 800 °C to 1300 °C, held at the peak temperature for 1 s, and their corresponding hardness was measured. The results showed that when the annealing temperature is approximately 1050 °C, the resulting hardness aligns with that of solution-treated specimens. To verify the accuracy of the proposed annealing temperature in the FEM simulation, this determined annealing temperature (1050 °C) was then applied in the FEM model to estimate the residual stress after 7-layer welding, with the results validated through measurements. The good agreement between the simulated residual stress and the measured results follows that the proposed annealing temperature of 1050 °C in FEM simulation is reasonable and effective. Therefore, the annealing temperature of 1050 °C should be included in the FEM simulation of SUS316 welding in the future.
