A concise review of Beilby's amorphous surface layers, discovered in early years of the twentieth century, is presented. While being treated mechanically the crystals form these layers characterized by an enhanced hardness and specific optical, electrical, and magnetic properties. The temperature stresses arising from a periodic contact of the abrasive with the crystal surface are supposed to be a reason for Beilby layer formation. A mathematical description of propagation of the temperature waves is given. The temperature wave amplitude is shown to be e times attenuated at the distance from the crystal surface being about the grain size.
