概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)

The samples were cross-section polished for EBSD measurement.

実験 / Experimental

The samples were cross-section polished using CP(SM-09010 and SM-09020).

結果と考察 / Results and Discussion

EBSD measurement was conducted following CP. The crystallographic information was obtained for the metallic layer structures(Fig.1). CP proved to be an effective preparation method for EBSD, as it provided a high-quality surface with minimal deformation, allowing for accurate indexing of the diffraction patterns. The reduction of surface artifacts and residual stress enhanced the clarity of the acquired data, improving the reliability of grain orientation and phase identification. Compared to conventional mechanical polishing, CP resulted in better Kikuchi pattern quality, which is crucial for precise crystallographic analysis. The superior surface finish obtained through CP contributed to higher indexing rates, making it a preferred method for EBSD measurements.
