Current pulses (approximately 10 3 A/mm 2 for about 20μs) have been applied to the drawing process of Cr17Ni6Mn3 and 4J42 (42Ni-56Fe) alloyed wire, the drawing stress being found to be decreased significantly. Furthermore, the ultimate tensile strength σ b was decreased and the elongation ratio δ (%) was increased with the application of the current pulses. In this experiment, the wire-drawing velocity of Cr17Ni6Mn3 was increased from 9m/min to about 60m/min, latter being the actual wire-drawing velocity employed in the factory. With the data of the magnetic properties of the Cr17Ni6Mn3, it was found that the saturated magnetization B s and the residual magnetization B r had decreased with the application of the current pulses. On the other hand, with the increase of the drawing speed, the decrease of the drawing stress had reduced, which accorded with the data of magnetic properties. Thus, the frequency of the current pulses should be increased with the increase of the wire-drawing velocity so as to ensure the electroplastic effect.
