Metamaterials, also known as lattice‐structured materials, imitate the multifunctionality of
natural architects as tailoring their physical properties is associated with manipulating their …

Additive Manufacturing (AM) techniques gained significant research interest in the past two
decades. AM techniques are the best alternative to traditional manufacturing processes for …

Abstract Metallic Functionally gradient materials (FGMs) are featured by gradually
distributed metallic compositions generating unique mechanical and physical property …

Additive manufacturing (AM) is known to generate large magnitudes of residual stresses
(RS) within builds due to steep and localized thermal gradients. In the current state of …

As functionally gradient materials (FGMs) reveal innovative mechanical properties, they
have aroused huge interest in multiple industry areas. In this study, a hybrid manufacturing …

Powder-based directed energy deposition is one of the major additive manufacturing
processes for producing and repairing large-size and high-value metallic components. Due …

Currently almost all the directed energy deposition (DED) processes are performed under
ideal lab conditions with the room temperature close to 20° C. By contrast, the cold …

Internal defects such as porosities are often formed in additively manufactured metal
components. The pores nucleate, grow, and coalesce to form cracks under loads, leading to …

Inconel 718 (IN718), a Ni-based superalloy, is immensely popular in the aerospace, nuclear,
