The investigation has been made of the effect exerted by high-frequency magnetic field on changing the structure and properties of the gray iron (С -3,16; Si -1,46; Mn-0,9; Cr -0,1; Ni- 0,18; Cu -0,5) produced using the method of continuous cyclic freeze crystallization casting. It is established that structure changes resulting from iron exposure by high-frequency magnetic-pulse field include “healing” of surface defects, perlite dispersion, decrease of ferrite amount in structure due to transformation of ferrite-graphite complex into perlite, coarsening and changing of internal graphite inclusion structures as well as changing the cementite morphology. The observed structure changes determine the hardness decrease of automobile parts of pistoncylinder unit. |
