Note that some cracks may not directly connect to the pores, but can be induced by the large deformation incompatibility at the grain boundary near a pore due to the high stress concentration. Although the crack propagation can consume some deformation energy and thus contribute to plastic ...
The weld zone produces severe plastic deformation and recrystallization under the action of the pin and shoulder of the welding tool. The reduction of the grain size and the increase of the grain number per unit area lead to an increase in the inhomogeneity of the grain and grain boundary in...
