Fatigue Life Evaluation and Prediction of Inconel 718 Manufactured by Selective Laser Melting

The prevalence of additive manufacturing (AM), or 3D printing, has grown in recent decades as a method of manufacturing complex geometries, prototype parts, or high tuned microstructures. One method of additive manufacturing is selective laser melting (SLM), a powder bed fusion technique which utilizes a laser to melt a metal alloy powder layer...

Fatigue Crack Propagation in Additively Manufactured and Functionally Graded Inconel 718

Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...

Fatigue Behaviour of functionally graded Inconel 718 manufactured by selective laser melting

Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...
