Materials Characterization Techniques

Materials Characterization Techniques encompass a broad suite of experimental methods used to probe and measure the structure, composition, and properties of a material. These powerful analytical tools, which include microscopy (e.g., SEM, TEM), spectroscopy (e.g., EDS, XPS), and diffraction (e.g., XRD), allow scientists and engineers to investigate a material's features from the atomic scale up to the macroscopic level. By revealing critical information about a material's crystal structure, elemental distribution, surface topography, and physical properties, these techniques are fundamental to understanding the processing-structure-property-performance relationships that are essential for quality control, failure analysis, and the research and development of new advanced materials.
