The acoustic emission (AE) characteristics from the fatigue crack propagation in SM50B-Zc steel were strongly affected by the environment medium. The AE feature from the fatigue process both in air and in 3.5 % NaCl aqueous solution manifested a periodicity which indicated the fatigue extension was discontinuous. The fatigue striation and secondary cracking were main AE sources during the fatigue crack growth in air. In contrast, AE during the fatigue crack propagation in 3.5 NaCl solution was released from the intergranular fracture and quasicleavage cracking.
