Abstract

Fracture toughness tests of the matrix and weld joint of 316LN stainless steel (SS) were carried out, while the acoustic emission (AE) signals were monitored simultaneously during the fracture process in real time. Then the AE signals were classified. The results show that the fracture of the matrix of 316LN SS and the weld joint was ductile ones, and the plasticity of the matrix was better than that of the weld joint. The fracture process could be divided into five stages including the crack tip opening stage, the elastic deformation stage, the plastic deformation stage, the crack initiation stage and the stable crack propagation stage. Moreover, the correlation analyses of rise time and duration of the AE signals indicated that the fracture processes could be classified into several categories, which was available for distinguishing the noise signal and effective fracture signal within the AE signal spectrum.

Key words: materials failure and protection fracture toughness acoustic emission technology 316LN stainless steel association analysis
