Significance of Defects
While most structural and functional materials are crystalline, many of their properties (e.g. mechanical strength, electrical conductivity, corrosion resistance) are actually determined by defects – deviations from the ideal (e.g. crystal) structure. This includes point-, line-, and planar defects, internal interfaces, and surfaces. For understanding and controlling materials properties, therefore, it is essential to investigate their defect population, known as the “microstructure.” The microscopy and microanalysis facility in the Swagelok Center for Surface Analysis of Materials (SCSAM) at Case provides superior tools for studying materials at the ;microscopic level, including state-of-the-art transmission electron microscopy (TEM).
