Acoustic emissions during tensile test of DC06 and HCT600X

authored by: Bernd-Arno Behrens, Sven Hübner, Kai Wölki
Abstract: In this paper the acoustic emission behaviour during tensile tests of the materials DC06 and HCT600X is studied. Two steels with different characteristics (mild deep-drawing steel DC06 and high-strength steel HCT600X) are consciously chosen to show the influence of the material properties on the generated acoustic emissions. The acoustic emission behaviour and the corresponding signals differ clearly from each other. In addition, the effect of the strain rate as well as the rolling direction (0°, 90°) on the acoustic emission behaviour is investigated. Both parameters have a significant influence on the resulting acoustic emissions during tensile deformation. Furthermore, a new criterion based on the acoustic emission parameter FCOG (centroid frequency) for detection of damage beginning in dual-phase steels is developed. The criterion supports the assumption that during tensile deformation of dual-phase steels two failure mechanisms, ferrite/martensite interface decohesion and martensite phase fracture, exist.
