| Abstract Scope |
Laser powder bed fusion (LPBF) additive manufacturing (AM) presents a novel approach for fabricating oxide dispersion strengthened (ODS) steels, known for their superior creep and tensile properties at high temperatures. This study utilized a Gas atomization reaction synthesis (GARS) method to create feedstock powder for ODS steels, effectively eliminating the need for conventional mechanical alloying. Using thermodynamic simulations coupled with melt pool analysis, microstructure of the ODS steels fabricated through LPBF was predicted and analyzed. These simulations are crucial in understanding the interactions between GARS powders and the LPBF process, particularly in identifying the optimal LPBF processing conditions. Considering the thermal behavior of the material and the dynamics of rapid solidification, this approach enables a deeper understanding of the material, paving the way for more efficient production of high-performance ODS steels with enhanced mechanical properties for high-temperature applications. |
