Abstract Scope |
Additive manufacturing (AM) creates hierarchical and heterogeneous microstructure that is sensitive to processing parameters and heat treatment. The microstructural effects on irradiation-assisted stress corrosion cracking (IASCC) have been reported but never systematically investigated. We employ microstructurally-graded specimens as a high-throughput approach to understand how microstructural variations caused by different laser parameters and heat treatments affect radiation damage and cracking resistance. The effects in grain size, crystallographic texture, dislocation cells, precipitation, dislocation recovery and grain recrystallization are simultaneously studied. The dominant mechanism of IASCC across the build parameters and heat treatments will be discussed. |
