ժҪ The effect of electropulsing treatment (EPT) on the microstructure of a Ti-based bulk metallic glass (BMG) has been studied. The maximum current density applied during EPT can exert a crucial role on tuning the microstructure of the BMG. When the maximum current density is no more than 2720 A/mm2, the samples retains amorphous nature, whereas, beyond that, crystalline phases precipitate from the glassy matrix. During EPT, the maximum temperature within the samples EPTed at the maximum current densities larger than 2720 A/mm2 is higher than the crystallization temperature of the BMG, leading to the crystallization event.
