Stress rupture initiated by the carbides in the grain boundaries of the multi-pass weld metal

Stress rupture initiated by the carbides in the grain boundaries of the multi-pass weld metal

The weld metal (WM) was generally regarded as one of the weakest zones in the dissimilar welded joints. The microstructure and fracture mechanism of the multi-pass WM are systematically probed in the present study. The scanning electron microscopy (SEM) results show more voids in the equiaxed grain...
