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.
