Heat treatment effects on Inconel 625 components fabricated by wire + arc additively manufacturing (WAAM)—part 2: mechanical properties

This study investigates the mechanical properties of the wire + arc additively manufactured Inconel 625 thin wall. The first part of this study focused on the microstructural features of the material after time-based annealing. This second part discusses the tensile strength and microhardness of the material after the same annealing procedure (980 °C, hold time 30 min, 1 h, and 2 h). It is found that the annealing procedure improved the ultimate...
