On the Potential of Using Selective Laser Melting for the Fast Development of Forging Alloys at the Example of Waspaloy

Forged high-performance components form the basis of technical innovations in the energy and transport sector. Great efforts are undertaken to develop new materials for forging, aiming at optimizing both the material performance and the effort needed for materials processing. In this work, gas atomization of powder and Selective Laser Melting (SLM) is explored as a new means to provide small, homogeneous samples of the desired alloys at reduced processing times. The work shows that thermomechanical treatment of the as-printed state allows to convert the additive manufactured (AM) microstructures into structures that are useful inferring on the forging properties of the considered alloy.
