Abstract

Abstract

En 中文
• Fatigue fracture mechanism of CSAM SS304L deposits was clarified. • Deposits at the AS state shows heterogeneous and severely deformed microstructure. • Fatigue strength improved due to strengthened integrity of inter-particle interface. • Fatigue fracture shifted to trans-particle mode with improved particle bonding.
