Abstract

In this paper a new approach about relation of ACOUSTIC EMISSION (AE) method and mechanical properties of FERRITE-martensite DUAL PHASE STEELs (DPS) has presented. The AE signals from a tensile test using a range of DPS with different volume fractions of MARTENSITE (VM) s, in the range of 12-65% VM, were obtained and their AE signals were investigated. In order to better study DPS internal behaviour, a function named “sentry function” was used. The amount of this function depends on the strain energy and ACOUSTIC EMISSION energy. the Results show that AE monitoring and sentry function are efficient tools for detection of micromechanisms, consisting of FERRITE-Martensite interface decohesion and/or MARTENSITE phase fracture, identifying the correlation of failure mechanisms to microstructure in DPS.
