Fracture toughness of Additively Manufactured and Functionally Graded Inconel 718

This study addresses the effects of additive manufacturing (AM) parameters and post-processing heat treatments on the microstructure and fracture toughness behavior of functionally graded and non-graded Inconel 718. Laser powers of 250W and 950W were used to fabricate non-graded and graded specimens. To study the effects of the microstructural...

Mechanics of bioinspired functionally graded soft-hard composites made by multi-material 3D printing

Functional gradients are material transitions that are found in nature and are known to result in materials with superior properties and multiple functionalities. The emerging multi-material 3D printing (=additive manufacturing, AM) techniques provide a powerful tool for the design and fabrication of bioinspired functionally graded materials ...
