Abstract

Abstract

Electro-pulse treatment was first used in bearing steel-GCr₁₅ in laboratory. The experimental results show that the solidification structure is fined significantly through changing in electro-pulse voltage. Simultaneously it is found that the perlities are coarsened gradually under the electro-scanning microscope. The mechanism of EPM for improving the solidification structure has been discussed as well.
