| Abstract Scope |
Laser beam powder bed fusion (L-PBF) process is an attractive additive manufacturing (AM) technology that is applicable for various applications and numerous metallic alloys. Haynes 282 is one of the gamma-prime strengthened Nickel based superalloys that is recently getting a lot of attention for AM components. The test specimens for this study were produced by a L-PBF system using an EOS 290 machine. The objectives for this study were to first develop the heat treatment procedures required for optimization of structure-property correlation in the AM L-PBF Haynes 282 superalloy. The microstructural evolution of test specimens during heat treatment processes was comprehensively studied by scanning/transmission electron microscopy (STEM) using Energy Dispersive Spectroscopy (EDS) and Backscattered (BS) detectors. Further, Materials Testing Database for uniaxial tensile and fatigue properties of the AM L-PBF Haynes 282 superalloy is provided at room and elevated temperatures. |
