Abstract

Abstract

En 中文
• δ phase orientation determines crack behavior: initiates or hinders propagation. • Homogenization enables uniform micro-cracks distribution, delaying fracture. • Achieve superior stress rupture life (44.87 h/760 MPa) in LPBFed GH4169. • Stable crack evolution process is key to enhancing high-temperature durability.
