Evaluation of the local tensile properties of austenite-ferrite welded joint
Apstrakt
Local mechanical properties (Yield Strength Re and Hardening Coefficient H') of austenite-ferrite welded joint has been evaluated by using finite element method to simulate the strain distributions obtained experimentally by tensile test using strain chains and strain gages. The three-dimensional model of V-joint (450) specimen has been used with seven materials simulating both base metals (BM), the weld metal (WM) and two sub-regions of two heat-affected zones (HAZ) fine grain (FG) and coarse grain (CG) HAZ. Tensile properties of CG HAZ and FG HAZ, needed for the calculation, were varied until numerical strain distributions matched closely enough the experimental ones, whereas tensile properties of BMs and WM were kept constant. Five different sets of tensile properties were used to match the experimental strain distribution. In this way local tensile properties of the whole austenite-ferrite welded joint have been evaluated.
