“…Microscopy (e.g., scanning electron microscopy, transmission electron microscopy), X-ray diffraction analysis, and other analytical procedures are frequently used in these techniques. Microscopy allows for a detailed analysis of the material's internal structure, while X-ray diffraction aids in identifying and distributing crystallographic phases [39][40][41]. Comprehensive characterization sheds light on the material's composition and distribution across the gradient.…”

Functionally graded materials (FGMs) are a remarkable invention in materials science and engineering, that offers unique properties useful in various applications. Having the ability to gradually change properties, like composition, microstructure, or mechanical properties of materials, gives FGMs unparalleled adaptability, making them suited for a wide range of high-strength applications. One of the novel methods of creating FGMs is to use severe plastic deformation (SPD) techniques on powdered materials. The SPD of powders involves a few critical steps; The process begins with selecting materials with varied compositions and phases then mixing the powders, cold compaction, SPD methods, and, if necessary, heat treatment. The process is completed with characterization and testing, to evaluate the microstructure and characteristics of the final FGM formed. FGMs will continue transforming materials engineering and pushing the boundaries of their applications in many engineering fields and industries since they exhibit attractive capabilities like improved efficiency, durability, and performance. Therefore, this article explores the process of fabricating FGMs by SPD and emphasizes its significance and future trends in FGM production.

Diamond, as a highly promising “extreme” semiconductor material, necessitates electronic property engineering to unleash its full potential in electronic and photonic devices. In this work, the diaphite nanoplatelet, consisting of (11) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes, is facilely synthesized using one‐step microwave plasma enhanced chemical vapor deposition method. The high‐energy plasma created by the pillar plays a crucial role in the formation. Importantly, altered electronic and optical properties are determined in the diaphite nanoplatelet through electron energy loss spectrum, density functional theory calculations, and cathodoluminescence spectroscopy. It is revealed that the strong sp3/sp2‐hybridized interfacial covalent bonding in the diaphite nanoplatelet induces the electron transfer from diamond to graphite. This modulates the electronic structure of the near‐interface layer of diamond and triggers a new local trapping band below the conduction band minimum within the bandgap. Consequently, the covalently‐bonded diaphite exhibits a different optical emission characteristic ranging from 2.5 to 3.64 eV, featuring a significant peak blueshift of 430 meV compared to the H‐terminated diamond. This work demonstrates a novel method to engineer the electronic properties of diamond, opening avenues for functional semiconductor device applications of diamond.
