Effect of Mo microalloying on impact toughness of X80 pipeline steel in SCGHAZ

The microstructure and impact toughness of subcritically reheated coarse-grained heat-affected zone (SCGHAZ) of X80 pipeline steels with different Mo content (0Mo and 0.11 wt%Mo) were investigated. Gleeble 3500 thermal simulation experiment was used to simulate the heat-affected zone (HAZ) of X80 pi...
