High Temperature Fatigue Behavior of Nickel based Superalloys manufactured by Selective Laser Melting

Experimental Setup for High Temperature Fatigue

The research project pursues three main aims where it comes together to improve the high temperature properties of Inconel 718 components manufactured by SLM:

The first aim of the project is to develop a detailed understanding of the different mechanisms at high temperature fatigue behavior of SLM-processed Inconel 718 alloy with different heat treatments at the microstructural level. Therefore, the present microstructure will be shown in detail for each sample condition and associated with the results of mechanical tests, so that the microstructural evolution are investigated, respectively.

The second aim is to characterize the effects of the hot isostatic pressing on the SLM material. In addition to an in-depth characterization of the surface, various high-resolution testing methods such as optical microscopy and electron backscatter diffraction can be used.

The third aim is the improvement of the functional encapsulation of laser melted Inconel 718 by Arc-PVD for post compacting by hot isostatic pressing.
