Acoustic-emission evaluation of the quality of

We propose a procedure for the evaluation of the quality of bimetallic rims of rock-crushing disks by the method of acoustic emission. According to this procedure, specimens are loaded by applying tensile forces at various points of the surface of the matrix. Normal and tangential stresses formed as a result provoke the development of defects which generate signals of acoustic emission.
