Abstract

Heat and thermochemical treatments of materials are commonly used in mechanical industries as an effective means of optimizing their mechanical properties. The lean towards a 100% quality approach exacerbates the need for nondestructive means to test the quality of treatment processes. In this paper, we will show the potential of electromagnetic methods for such tests through three industrial applications: analysis of nitriding multilayers with 3MA, stress profile evaluation by 3MA and retained austenite ratio by 3MA and Barkhausen Noise.
