Abstract

The invention relates to a method for ultrasonically detecting a metal material texture, belongs to the field of material characterization, and solves the problems that in the prior art, a metal material is thick and large, and sample texture information is difficult to quickly obtain. The method comprises the following steps: step 1, processing a sample; step 2, ultrasonic sound velocity detection; uniformly collecting on the rolling direction surface and the normal direction surface of each sample to obtain 125 rows * 125 columns of ultrasonic signals; 3, fitting the ultrasonic sound velocity and the deflection angle; 4, converting the sound velocity into a deflection angle and matching; 5, Euler angle conversion and orientation information visualization are carried out; the method comprises the following steps: firstly, acquiring Euler angle data, then importing the Euler angle data into texture analysis software TSL OIM Analysis, and obtaining a calculation pole graph to realize orientation information visualization. According to the method, rapid characterization of metal material texture information is realized.

Description

technical field [0001] The invention relates to the technical field of texture characterization, in particular to a method for ultrasonically detecting the texture of metal materials. Background technique [0002] Texture often occurs during the preparation and processing of polycrystalline materials. As a special organizational structure, texture is an important reason for the anisotropy of mechanical properties of polycrystalline materials. [0003] In the process of studying the anisotropy of polycrystalline materials, the commonly used characterization methods include X-ray texture detection technology (XRD method), electron backscatter diffraction technology (EBSD method) and neutron diffraction method. The XRD method and EBSD method mainly detect the surface texture information of the sample. The XRD method has good statistics, the EBSD method has high precision, and the neutron diffraction method can collect the sample body information. However, the detection conditio...
