Mechanical characterization of titanium alloys linear friction welds
Résumé
Similar Ti17-Ti17 LFW joints were studied. Microhardness tests were conducted to track the weld zones areas and locations. Digital Image Correlation (DIC) provided the strain field of the specimen surface. Tensile test and DIC results allowed us to identify constitutive law of the joint by fitting an isotropic hardening behavior to the weld zones. Constitutive law coefficients were mapped using the weld zones tracking. A simulation of the tensile test was performed using Z-Set. Tensile test simulations were in good accordance with the experimental results.
