摘要：
The tensile tests with microscopic morphology analysis and microstructure-based finite element simulation were conducted to study the deformation and failure behavior of weld metal in different orientations. Strain localization in grain boundary ferrite is triggered by heterogeneous tensile deformation. The delamination along the interface between grain boundary ferrite and acicular ferrite dominates the failure of the longitudinal specimen characterized with equal-axis dimples; a mixture of equal-axis and shear-type dimples in the transverse specimen can be attributed to the localized plastic shear deformation and the interface decohesion. The plastic strain localization could be considered as a conservative predictor of ductile failure.
