Effect of V Content and Heat Input on HAZ Softening of Deep-Sea Pipeline Steel

Effect of V Content and Heat Input on HAZ Softening of Deep-Sea Pipeline Steel

In this paper, the welding thermal cycle process of deep-sea pipeline steel was investigated by welding thermal simulation. The microstructure evolution, crystallology and second-phase precipitation behavior of the soft zone of the heat-affected zone (HAZ) were characterized and analyzed by combinin...
