The effect of different microstructures,obtained under different tempering temperatures on acoustic emission (AE) characteristics and source mechanisms during tensile deformation,was investigated in this study.Different heat treatments were carried out on hot-rolled low-alloy steels to obtain different microstructures (ferrite/pearlite,tempered martensite and tempered sorbite) and the AE
