Abstract Scope |
Stainless steel (SS) 316H is a promising candidate for structural components in nuclear reactors because of its higher temperature range (higher than 500 °C), corrosion resistance, and attractive mechanical properties. Laser Powder Bed Fusion (LPBF) is a popular method for additive manufacturing of metal components however studies about the effects of print parameters on microstructure and mechanical properties are a great need for the nuclear industry. Recrystallization is an important material process that can lead to grain refinement and eliminate the internal stress of metal components. This study aims to compare the microstructures of LPBF 316H with three different scan speeds and determine the scan speed effects on the recrystallization temperature. Results showed a negative correlation between changes in scan speed and recrystallization temperature. There were also differences in microstructures for the different scan speeds post-recrystallization. |
