Abstract
Holes are one of the most critical features of aero-engine components subjected to fatigue loads. Thus, it is essential to ensure a good surface integrity during hole making operations. This work proposes a non-destructive procedure based on X-ray diffraction measurements to determine residual stresses and white layers in holes. Drilling tests were done in Inconel 718 using new and worn tools for different cutting conditions. The results showed that residual stresses can be determined non-destructively with ±150 MPa error. Importantly, Full Width at Half Maximum values showed an unequivocal agreement with the presence of white layer and plastic deformation.
期刊介绍：
NDT&E international publishes peer-reviewed results of original research and development in all categories of the fields of nondestructive testing and evaluation including ultrasonics, electromagnetics, radiography, optical and thermal methods. In addition to traditional NDE topics, the emerging technology area of inspection of civil structures and materials is also emphasized. The journal publishes original papers on research and development of new inspection techniques and methods, as well as on novel and innovative applications of established methods. Papers on NDE sensors and their applications both for inspection and process control, as well as papers describing novel NDE systems for structural health monitoring and their performance in industrial settings are also considered. Other regular features include international news, new equipment and a calendar of forthcoming worldwide meetings. This journal is listed in Current Contents.
