Fig. 11. 3D volume renderings taken from the μCT images for the tensile test piece loaded to (a) 0 MPa, (b) 210 MPa, (c) 344 MPa and (d) 375 MPa showing the original voids (rendered yellow) and the new initiated voids (rendered black – also shown in magnified inset). The black solid lines indicate the fusion boundary. The fusion boundary is approximated with reference to the weld macrostructure in the metallographic image. And the location of FQZ is outlined according to its nearly 100-μm wide feature. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
