Microstructure and toughness of thick-gauge pipeline steel joint via double-sided friction stir welding combined with preheating
Fusion welding easily causes microstructural coarsening in the heat-affected zone (HAZ) of a thick-gauge pipeline steel joint. This is most significant in the inter-critically coarse-grained HAZ (ICCGHAZ), whi...
