Abstract

The high-frequency magnetic field influence on changes in the structure and properties of CЧ-25 cast iron obtained by the method of continuous-cycle freeze casting has been studied. It has been found that the structure effects of high-frequency magnetic-pulse action on cast iron are the “healing” of surface defects, perlite dispersion, a decrease in the ferrite content in the structure due to the ferrite-graphite complex transformation into perlite, coarsening and modification of the internal structure of graphite inclusions, and a change in the cementite morphology. The observed structural changes determine the decrease in hardness of automobile parts of the cylinder-piston block.
