Abstract

Mechanical behavior of an AISI/SAE 8620 steel and of a sintered Fe-P alloy has been investigated using acoustic emission signals. Four-point bending tests were carried out using strain gages to measure the deformation. The onset of plastic strain was determined through the acoustic signal. The acoustic signal of the sintered material was very strong and increased continually with external load. The correlation between microstructure and signal acoustic is discussed.
