Acoustic Emission from Ferrous Martensites,
Abstract
Acoustic Emission during Martensitic transformation of two Fe-Ni-C alloys (31.4 Ni-0.03C and 22 Ni-0.44 C) has been investigated as a function of their thermo-mechanical history. Starting conditions examined include a) as annealed equiaxed austenite (gamma) b) 20, 50 and 80% rolling of (a) at room temperature, c) transformed to martensite (alpha prime) and then rapidly reverted to gamma, d) reverted gamma from 20, 50 and 80% deformed alpha prime e) reverted gamma after 5 thermal cyclings with or without prior deformation. Acoustic emission total counts were monitored as a function of temperature (Modified author abstract)
