In the state analysis using EPMA, changes (shifts and shapes) in the characteristic X-ray peak wavelengths due to differences in the chemical bonding states (ionic valence, crystal structure, coordination number) of oxides and silicates are utilized to estimate the bonding states by comparing with standard spectra. In the identification of two types of copper oxides, when distinguishing between black CuO and red Cu2O by color is difficult, especially for microscopic objects that require an electron microscope, it is possible to grasp the oxidation state using EPMA. Additionally, while XPS is effective for measuring thin oxide layers on aluminum surfaces, EPMA can be used to understand the oxidation state of small foreign particles, bulk materials, and composites. 【Device Specifications】 ■ Manufacturer: JEOL Ltd.

The EBSD (Electron Backscatter Diffraction) method obtains orientation information of individual crystals from the electron diffraction patterns generated by electron beam irradiation and maps this information. It is a technique used to investigate not only crystal orientation (texture) but also material microstructural states such as grain distribution and stress-strain as quantitative and statistical data. For example, when the sample is tilted significantly in a SEM and the electron beam is irradiated, if the sample is crystalline, electron diffraction occurs within the sample. By indexing the resulting pattern, it becomes possible to determine the crystal orientation at that point. By observing the differences in crystal orientation, it is possible to infer the residual stress within the crystal grains. 【Features】 ■ Obtains and maps orientation information of individual crystals ■ Investigates material microstructural states such as crystal orientation, grain distribution, and stress-strain ■ Allows inference of residual stress within crystal grains by observing differences in crystal orientation *For more details, please refer to the PDF document or feel free to contact us.
