摘要：
Magnetic hysteresis properties of cementite obtained by the method of mechanical alloying have been studied. It is shown that the strongly deformed cementite is in a low-coercivity state, and the cementite annealed at 500A degrees C is in a high-coercivity state. The need to allow for the contribution of the coercivity of cementite to the coercive force of high-carbon steel is shown. Taking into account this point of view, the behavior of the coercive force depending on the degree of cold plastic deformation by drawing is explained for a number of carbon steels with a structure of fine platelike and globular cementite.
