摘要: Abstract Electropulsing treatment (EPT) was performed on a nickel base corrosion resistant alloy during aging. The effect of EPT the microstructure and resistance mechanisms were investigated. results show that intergranular can be improved substantially without degradation mechanical properties by EPT. has an enhancing interface diffusion rate alloying element, which is higher than body rate. And thus discontinuous precipitation M 23 C 6 type carbides appears at grain boundary in EPT, decreases depletion extent elements substantially. As result, any properties.
