In this study, the effects of Mo and Nb on microstructure Charpy impact properties coarse-grain heat affected zone (CGHAZ) in high-strength low-alloy (HSLA) steels were investigated. The high-Mo steel had a lower volume fraction acicular ferrite (AF) higher granular bainite (GB) than those low steel. CGHAZ specimen AF GB compared to low-Mo specimen. This is because, an increase lowers transform...

Continuous cooling transformation (CCT) diagrams of base metals are common in welding. They can be built using physical or numerical simulations, each with advantages and limitations. However, those not usual for weld metal, considering its variable composition due to the dilution into metal. Wire Arc Additive Manufacturing (WAAM) is a distinctive case which interest materials comparable raises...
