The mechanism of strength matching in governing the high-temperature creep of G115 steel welded joints

Key Points

• Creep behavior of G115 steel welded joints is influenced by the strength matching mechanism, which governs the material's responses.
• Key evidence shows that optimal strength matching can reduce high-temperature creep rates in welded joints by up to 30%.
• The study employs comparative analysis of G115 steel joints under high-temperature conditions to assess creep characteristics.
• Optimizing strength matching may enhance performance but requires further research into long-term effects and durability.
