Description

technical field [0001] The invention relates to an ultrasonic three-dimensional imaging method for lamellar defects, in particular to an ultrasonic three-dimensional imaging detection method for the distribution of lamellar defects inside a material. Background technique [0002] There are many lamellar defects in the process of material processing, such as folds, cracks, lamellar inclusions, etc. These defects have an adverse effect on the performance of the material. Accurate evaluation of the size, extension, and distribution of the above-mentioned defects plays an important role in improving the new energy of materials and promoting process innovation. Three-dimensional ultrasound imaging can provide rich three-dimensional structure information, and has been widely used in the medical field. Theoretically, the defect distribution inside the material can be non-destructively measured by ultrasonic three-dimensional imaging technology. However, due to the large amount of...
