Description
Technical Field
The invention belongs to the technical field of material testing and analysis, and particularly relates to an angle measuring device which is suitable for texture testing and in-situ measuring processes of a large sample.
Background
In material science, because a material preparation process usually involves obvious force and thermal coupling processes, the orientation distribution of crystal grains in the material at different spatial positions is not strictly uniform, and a certain preferred orientation (namely texture) is shown. Due to the presence of the texture, the material properties also tend to exhibit some directional dependence (i.e., anisotropy). Therefore, the texture is one of the important bases for the control of the material preparation process and the design of service performance. Accordingly, texture measurement is also one of the important links in material science research. The texture can be divided into micro and macro textures according to the difference of the measurement area or scale. The texture measured by the electron back scattering method is generally referred to as a micro texture, while the texture measured by the X-ray and neutron diffraction methods becomes a macro texture. Macroscopic textures are generally more representative than microscopic textures due to the larger sampling volume using X-ray and neutron diffraction methods. In contrast, the macroscopic texture measured by neutron diffraction is more statistically significant than that by X-ray because of the weaker X-ray penetration (only surface measurements can be made) and the neutron has a penetration depth in the order of centimeters (thousands of grains can be measured). In the measurement of the macro texture, the orientation distribution of crystal grains in a three-dimensional space in a sample needs to be analyzed. The angle measuring device is an important component for realizing the three-dimensional attitude control of the sample, namely, any three-dimensional space position of the sample can be defined based on a spherical coordinate system by accurately controlling the rotation and the tilting angles of the sample. However, the existing goniometer is of a closed-loop circular structure, has small internal space and bearing capacity, is suitable for texture testing of small samples (usually with the volume less than 1 cubic centimeter and the weight less than 10 grams) made of conventional materials, and cannot meet the requirements of testing large samples (such as the volume more than or equal to 1000 cubic centimeters and the weight more than or equal to 10 kilograms) of components and the like or in-situ measurement under different environmental loads such as temperature, stress and the like. Therefore, an angle measuring device suitable for large sample texture testing and in-situ measurement is not available at present.
The internal texture information of large samples such as components and the like and the evolution of textures under different environmental loading conditions are often closely related to the manufacturing process and service performance of engineering components, so that the method has a certain scientific guiding significance. Therefore, it is necessary to develop an angle measuring device that solves the problems of the conventional angle measuring device, such as small internal space and load bearing, and suitability for the conventional small sample texture test, so as to support the engineering component manufacturing and service evaluation.
