Abstract : Acoustic Emission (AE) during martensitic transformation of two Fe-Ni-C alloys (31.4 Ni-0. 03C and 22 Ni-0.44 C) was investigated as a function of their thermomechanical history. The use of AE technique for M sub s temperature determination in alloys steel is discussed. This study was a part of an alloy development program and demonstrated the merit of AE technique for this application. In all, 15 different steel compositions were examined.
