“…Ceramic particles tend to exhibit harder and more brittle properties of MMCs in comparison with their metal counterparts [107,108,115,116]. They can provide excellent attributes, such as wear resis-tance, corrosion resistance, high-temperature stability, weight reduction, and lower thermal expansion coefficient, compared to metal reinforcements [117][118][119][120][121]. However, employing ceramic particles instead of metals may entail trade-off drawbacks, such as relatively low ductility and toughness, and thermal conductivity [122,123].…”

Particle-reinforced metal matrix composites (MMCs) produced using the laser powder bed fusion (LPBF) technique have gained considerable attention because of their distinct attributes and properties in comparison with conventional manufacturing methods. Nevertheless, significant challenges persist with LPBF-fabricated MMCs: more design parameters over commercially available alloys and several defects resulting from inappropriate process conditions. These challenges arise from the intricate interaction of material- and process-related phenomena, requiring a fundamental understanding of the LPBF process to elucidate the microstructural evolution and underlying mechanisms of strengthening. This paper provides a comprehensive overview of these intricate phenomena and mechanisms, aiming to mitigate the process-related defects and facilitate the design of MMCs with enhanced mechanical properties. The material processing approach was suggested, covering from material design and LPBF to postprocessing. Furthermore, the role of in situ heat treatment on the microstructure evolution of MMCs was clarified, and several novel, potential strengthening theories were discussed for the LPBF-fabricated MMCs. The suggested strategies to address the challenges and design high-performance MMCs will offer an opportunity to develop promising LPBF-fabricated MMCs, while overcoming the material limitations of LPBF.

“…The metal alloy samples undergo a phase transformation from a mixture of NiAl and Ni3Al phases to a single NiAl phase with increasing sintering temperature. The ceramic samples undergo a phase transformation from α-Al2O3 to a mixture of α-Al2O3 and γ-Al2O3 at 1300°C, and then back to α-Al2O3 at 1400°C [24][25][26][27][28]. The presence of defects, such as dislocations, grain boundaries, and pores, in the sintered samples can have a significant impact on the properties of the final products.…”

The microstructural evolution of materials during powder metallurgy and ceramic forming processes is a complex phenomenon that spans multiple length scales. In this study, we present a comprehensive multiscale characterization of the microstructural changes occurring during these processes. We employ a combination of advanced experimental techniques, including high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), and X-ray diffraction (XRD), to investigate the microstructural features at various length scales. Our results reveal the intricate interplay between grain growth, phase transformation, and defect formation during sintering and forming processes. We observe a strong correlation between the initial powder characteristics, such as particle size and morphology, and the resulting microstructure. Furthermore, we employ phase-field modeling to simulate the microstructural evolution and validate our experimental findings. Our simulations provide insights into the kinetics of grain growth and the role of interfacial energy in governing microstructural changes. The results of this study have significant implications for the design and optimization of powder metallurgy and ceramic forming processes, enabling the tailoring of microstructures for specific applications. This work contributes to the fundamental understanding of microstructural evolution in these processes and paves the way for the development of advanced materials with tailored properties.

“…[11][12][13] Most of the titanium alloys with functional gradients are prepared based on differences in materials compositions, rather than on microstructural features such as grain size. [14][15][16][17][18] However, it should be noted that due to the poor solubility of titanium in other metallic elements, it is prone to forming thermodynamically stable intermetallic phases that can affect the mechanical properties of the alloy. In this regard, a new method of preparing functional gradient structures based on the inherent microstructural differences in the material itself has been proposed.…”
