Abstract
The nature of the Acoustic Emission (AE) generated during tensile deformation and fracture of two austenitic alloy PE-16 are presented and discussed. Effects of second phases are carbides and cohirent precipitates i.e., Ni3(Al, Ti). Time and frequency doma in analyses have been used to characterise the dislocation behaviour. Correlations of dynamic strain ageing in 316 SS with AE signal are presented. A method to amplify the weak AE signals in 316 SS is highlighted. The studies in PE-16 have shown that AE can be correlated with the type of interactions i.e., whether Orowan looping and/or particle shearing is operating.
