Continuous cooling transformation diagram and mechanical properties in weld coarse-grain heat-affected zone of API X70 steel

In the present work, continuous cooling transformation (CCT) of coarse-grained heat-affected zone (CGHAZ) and simulation of Charpy-sized impact specimens were performed using a Gleeble 3800 thermomechanical simulator. Results obtained from the dilation studies show significant effect of cooling rate...
