The bead on plate test method was employed to investigate the effect of single pass welding heat input microstructure and hardness submerged arc welded high strength bainitic steel. weld metal contains very volume fraction acicular ferrite regardless input. By contrast, with increase in input, main coarse grained affected zone (HAZ) changes from a mixture lath martensite sideplate full sideplate. Microhardness measurement showed that maximum values always present at HAZ under lower...
The difference in transformation mechanisms between the normal and reverse phase medium Mn steel was revealed using thermodynamic kinetic analysis. results indicate that austenite formation during is a fast reaction, significant amount of 46.9 vol% retained obtained after subjected partial reversion at 650 °C × 1 h. At nucleation stage, lath-like structure, dislocations, martensitic packet boundaries, grain boundaries provide high-density sites for formation. critical temperature reduced by...
