Abstract

Fabrication of functionally graded materials-FGM is an emerging technique in the field of additive manufacturing-AM. FGM is used in many applications like the marine, aerospace, and automobile sectors. This study gives first-hand knowledge on the mechanical and microstructural characterization of additively manufactured FGM wall (Commercially pure titanium (CP-Ti/Ti-Grade-9) using gas tungsten arc welding-GTAW based AM. Experimental results revealed that this particularly manufactured wall has shown better properties such as tensile strength, impact energy, hardness, and microstructural characteristics when compared to wrought alloys. Scanning electron microscopy-SEM analysis indicates the ductile mode of failure that occurred in the fractured samples. This research has successfully fabricated FGM with spatially improved properties. © 2022 Elsevier B.V.
