Abstract
The influence of the exposure duration of nanosecond electromagnetic pulses (NEMI) on crystallization, structure and properties (hardness, density, microhardness of structural parts, corrosion resistance, wear-resistance) of low-silicon cast iron is examined. It is found that the increase in duration of NEMI exposure on the melt results in the increase of starting temperature for eutectic and eutectoid transformation. Physical and mechanical properties of cast iron vary considerably depending on the melt exposition duration (MED) according to extreme dependence with maxima and minima properties under of 10 – 15 min. For example, the thermal conductivity of the melt increases two or more times.
