摘要

摘要:本文介绍了旨在检测用于进一步处理的元素的次表层不连续性的测试结果。对于不连续点的初始识别，采用了计算机断层扫描的方法。根据所选典型缺陷的层析成像和材料电导率的测量，确定了涡流测试的参数。在约0.48 mm深度的次表层中检测到一系列不连续性。这允许在加工的给定阶段，选择相关的元件进行进一步加工。

Detection of Sub-Surface Defects in Semi-Finished Products from Aluminum Alloys by the Eddy Current Method

Abstract The article presents the results of tests aimed at detecting discontinuities in the subsurface layer of elements intended for further processing. For the initial identification of discontinuities, the method of computed tomography was used. Based on the tomographic images of selected typical defects and measurements of the electrical conductivity of the material, the parameters for the eddy current tests were determined. A series of discontinuities in the subsurface layer to a depth of about 0.48 mm were detected. This allowed, at a given stage of machining, relevant elements to be selected for further processing.
