| Summary: | Inconel 725 commonly used in aerospace and marine industries for its excellent
strength and corrosion resistance, these properties however are dictated by its
microstructure. With additive manufacturing becoming an increasingly important
manufacturing technique to allow damaged parts to be repaired to promote
sustainability, printed Inconel 725 is being studied to compare its performance against
traditional manufacturing techniques. This paper intends to gain insights of the microstructural features by using optical microscope, scanning electron microscope. Techniques like electron backscatter
diffraction and energy dispersive spectroscopy will be used to characterize the Inconel
725 samples. The mechanical properties of Inconel 725 will be analysed with Vickers
hardness test to compare how it can be affected by building height. This paper will
then conclude by summarizing the notable results obtained and recommendations. |
