Background

Determination of crystal orientation, orientation difference or orientation relationship, and grain boundary index is one of the main tasks accomplished by the EBSD technique. The crystal orientation analysis function makes the EBSD technology become a new standard micro-zone texture analysis technology.

The EBSD is used for measuring the microscopic textures of plate and strip products such as electrical steel, automobile plate IF steel and the like, and the performance and the textures have direct relation. It is important whether the sample is in alignment or not, since this will directly affect the measurement result, otherwise the measurement error will be increased and even a wrong test result will be obtained.

Because the plate strip sample is thin, the sample preparation is generally carried out after the inlaying. The circular inlaid sample size is bigger, if the sample is directly stuck on a general sample seat, the sample is difficult to be straightened, a large sample can block the horizontal straight line edge of the end part of the pre-tilt table by 70 degrees, and the edge of the plate strip sample is difficult to be ensured to be parallel to the horizontal straight line edge of the end part of the pre-tilt table. And the mosaic sample is also heavier, if a traditional fixing mode is adopted, the vertical direction of the sample table is inclined by 70 degrees, and the sample is easy to slide in the testing process under the action of gravity, so that the originally set detection area is changed, the picture is deflected, and the test result is inaccurate or even fails.

In prior art, only adopt the mode of level placing the sample to carry out test operation to the sample, the sample circular dimension is inlayed to the slab band is big be difficult to the alignment, and it is great to inlay sample weight, can appear removing in the testing process, leads to final image drift, and experimental failure has reduced work efficiency when increasing the operation degree of difficulty, brings inconvenience for user's use.
