TOMOGRAPHIC ANALYSIS METHOD
A method for the tomographic analysis detects anomalies in a part. The method includes the steps of acquiring at least one three-dimensional image of the part by means of a tomography device; subdividing the image into elementary subparts; analyzing a grayscale distribution in each subpart; obtaining at least one parameter representative of said grayscale distribution for each subpart; and comparing the one or more parameters obtained for each subpart with standard values characteristic of a defect-free region. The method further includes the steps of detecting abnormal subparts for which the one or more parameters differ from the standard values; determining risk regions, which comprise each abnormal subpart and each subpart adjacent to at least one abnormal subpart; and analyzing the risk regions in order to detect the anomalies in the part.
DETECTION OF CRYSTALLOGRAPHIC PROPERTIES IN AEROSPACE COMPONENTS
Aspects of the disclosure are directed to an analysis of a material of a component. A radiation source is activated to transmit radiation to the component. A beam pattern is obtained based on the component interfering with the radiation. The beam pattern is compared to a reference beam pattern. An anomaly is detected to exist in the material when the comparison indicates a deviation between the beam pattern and the reference beam pattern.
