Search for high-creep-strength welding conditions considering HAZ shape factors for 2 1/4Cr–1Mo steel Weld. World (IF 2.1) Pub Date : 2024-03-16
Abstract The creep rupture life of ferritic heat-resistant steel weld joints is limited by Type IV cracking that occurs in the heat-affected zone (HAZ), whose shape affects creep damage accumulation. In this study, we address the inverse problem of extending the creep rupture life of weld joints by controlling HAZ shape via welding conditions. As reported separately, we have developed a workflow that
