| Abstract | Additive manufacturing is an emerging manufacturing and remanufacturing (repair) technique for value-added materials such as Inconel 718, particularly using a laser beam as the heating source. In this research work additive manufacturing of Inconel 718 using a continuous wave fiber laser and filler wire feed was studied. To simulate industrial conditions, the deposits were built on parent metal substrates that were extracted from an after-service Inconel 718 aerospace component. The evolution of the macrostructure, defects, microstructure and hardness of the deposits was evaluated in the as-deposited and post-clad heat treated conditions. The hardness of the laser deposits can be fully recovered to the level of the after-serviced parent metal after solution heat treatment and aging. The high integrity deposits had no visible pores but only some minor weld metal liquation cracking, which indicates the great potential of the laser deposition process to manufacture and repair superalloy components for aerospace applications. |
