Abstract Using the technique of acoustic emission energy, the deformation and fracture in low strength and high plastic α-Ti has been studied. The logarithm of total acoustic emission energy is proportional to the logarithm of long range stress, and its turning point corresponds to the point of cracking. Therefore, it seems to be available to determine accurately the state of the cracking tip of these low strength and high plastic alloys by the method.Two kinds of acoustic emission sources were found during the plastic deformation and fracture process of α-Ti: the dislocation movement and the microcracking and growth of a crack.
