“…Therefore, a new treatment approach, the electropulsing treatment (EPT), is carried out to optimize the microstructure of cemented carbide. [6][7][8][9][10] The EPT, also known as the electric current pulses treatment, [11] is a newly developed processing method that applies a high density of current pulses to materials in a short time. Compared with conventional heat treatments, the EPT has the advantages of environmental protection, economy, energy savings, and high efficiency.…”

Electropulsing treatment (EPT) is a promising postprocessing method to optimize microstructure. In the present work, the EPT was applied to treat cemented carbide (WC-15Co). The electropulse-induced microstructural evolution in WC-15Co was investigated. Compared with the untreated sample, the transverse rupture strength and electrical resistance of the treated sample were reduced. However, there was no significant change in the scanning electron microscopy (SEM) microstructure. Therefore, electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) were carried out to detail the microstructural evolution. This process revealed that electropulsing could promote the recrystallization and the transition of e-Co to a-Co, as well as the evolution of microstructure. In addition, the dislocations in the treated sample were significantly fewer than those in the untreated sample.
