| Abstract Scope |
Inconel 718 (IN 718) is a Nickel-based superalloy that has many different applications including aerospace turbine blades and nuclear reactors and is known for its good corrosion resistance, creep, and mechanical properties at high temperatures. IN 718 has been widely produced using laser powder bed fusion (LPBF), and has three major precipitation phases: γ’, γ’’, and δ phase. In this study, we performed cold rolling on LPBF of IN 718 to different strain levels. Cold working increases the dislocation density and has also changed the nanoprecipitates in terms of the precipitate size and density. The influence of cold working on microstructure and subsequent evolution of mechanical behaviors, such as work hardening, is discussed. |
