WebIn this study, different eddy-current based probe designs (absolute and commercial reflection) are used to detect artificial defects with different sizes and at different depths in parts composed of stainless-steel (316) and titanium (TI-64) made by Laser Additive Manufacturing (LAM). The measured defect signal value using the probes is in the ... Web[14, 19] Another possibility to achieve more accurate results is to use eddy current testing as the excitation frequency can be varied and different studies demonstrate a good correlation between the martensite content and measured values in eddy current testing. ... which is a widely used metastable stainless steel. The data obtained ...
