Abstract Scope |
Haynes 282 (H282) is a nickel-based superalloy which is better suited for processing via laser powder bed fusion (LPBF) compared to other alloys with similar high temperature mechanical properties. This makes it an ideal material for LPBF manufactured components that need to operate in high-temperature conditions. However, the mechanical properties are dependent on the microstructure and texture, which can vary greatly in LPBF parts. Thus, understanding the relation between the printing parameters and the resultant microstructures is crucial for ensuring optimal part performance. In this work, H282 samples were fabricated using a variety of printing conditions and post processing heat treatments. Microscopy and x-ray diffraction were used to characterize the variation in microstructure and texture among the samples. Mechanical testing was also performed to investigate the tensile and creep performance of the printed H282. |
