Charpy impact toughness in all directions with respect to
In this study, the Charpy V-notch (CVN) values were investigated in all directions [longitudinal-transverse (L-T), T-L, short-transverse (S-T), T-S, L-S, S-L, and at 45°] with respect to the rolling direction (RD) of American Petroleum Institute (API) 5L X52 steel welded by electric resistance welding (ERW). In addition, the microstructures and …
