Microstructure Refinement of Hypereutectic High Chromium Cast Iron with Electric Current Pulse

Abstract:

The effect of electric current pulse (ECP) on the solidification structure of hypereutectic high chromium cast iron was studied. The orthogonal array L9 was used to determine the effect of three process parameters of ECP, which were electric voltage, pulse frequency, pulse width. According to the experimental results, the solidification structure of hypereutectic high chromium cast iron was modified from large grains to finer grains with equiaxed crystals, by allowing the ECP to act on liquid.
