By confirming the shape changes of the metal structure and measuring internal strain using EBSD, it is possible to determine whether the bending processes of leaf springs, hair springs, and others are appropriate.
Electron Backscatter Diffraction Pattern (EBSD) allows for the following when combined with a Scanning Electron Microscope (SEM): - Analysis of crystal orientation after cross-section formation - Confirmation of shape changes in metal microstructures and internal strain distribution In this case, we introduce "internal strain measurement of wire materials" using EBSD. This measurement technique is useful for determining whether bending processes, such as those for leaf springs and hair springs, are appropriate and for setting processing conditions. We encourage you to give it a try. Additionally, our company conducts various cross-sectional analyses using TEM and surface analysis using XPS, enabling multifaceted analytical evaluations. Both sales and technical staff are available to assist directly, so we would be grateful if you could feel free to consult with us. Seiko Future Creation Official Website https://www.seiko-sfc.co.jp/
