Title:
METHOD FOR ACCURATELY REPRESENTING CRYSTAL THREE-DIMENSIONAL ORIENTATION AND CRYSTALLOGRAPHIC ORIENTATION
Document Type and Number:
WIPO Patent Application WO/2021/027264
Kind Code:
A1
Abstract:
A method for accurately representing a crystal three-dimensional orientation and a crystallographic orientation, comprising the following steps: acquiring a two-dimensional tissue topography and an EBSD pattern in an area to be detected of a crystal material; using three-dimensional image analysis software to perform three-dimensional image synthesis so as to obtain a three-dimensional topography; extracting a three-dimensional orientation of a characteristic topography in a coordinate system where the three-dimensional topography is located; and by converting the three-dimensional orientation into a crystallographic coordinate system obtained by EBSD, obtaining the crystallographic orientation of the characteristic topography. By using the method, the orientation of characteristic organization structures of various materials and the crystallographic orientation may be simultaneously analyzed, which has a great significance for research on the material crystal growth orientation and growth behavior.
