摘要：

This study examines the relationship between thermal histories obtained via IR imagery and final local mechanical properties in Inconel 718 walls built via directed energy deposition. Four processing conditions were designed to provide distinct thermal histories in twelve built walls. Mechanical properties were obtained from miniature tensile samples cut from various locations within each wall. The work identified two critical temperature ranges associated with microstructure evolution and demonstrated the capability to predict properties based on time spent in the two ranges, paving the way for future process control.
