![[Example of Analysis by EBSD] Screw](https://image.mono.ipros.com/public/product/image/d61/2000533368/IPROS90868083247351914914.png?w=280&h=280)
We will introduce an example of analysis using EBSD for screws (Cu2Zn).
The EBSD method allows us to confirm the distribution of crystal sizes and the orientation of crystal orientations. In this case, it was found that there is a significant orientation difference in the valleys of the screw, suggesting that there is a large residual stress. Additionally, it was observed that small crystal grains are distributed on the surface of the screw. [Summary] ■ Analysis Method - Observation of crystal structure using EBSD ■ Results - It was found that there is a significant orientation difference in the valleys of the screw - It is inferred that there is a large residual stress - It was also observed that small crystal grains are distributed on the surface of the screw *For more details, please refer to the PDF document or feel free to contact us.
