An investigation into the effects, including the athermal effect, of a pulsed current on AZ31B magnesium alloy was carried out. Different peak current densities were applied at the same temperature under uniaxial tensile testing. The results indicate that the stress reduction caused by the increasing peak current density is independent of temperature. The strain hardening coefficient also shows a similar trend. The fracture strain shows the optimum value due to the current crowding effect.
对脉冲电流对AZ31B镁合金的影响（包括非热效应）进行了研究。在单轴拉伸试验中，在相同温度下施加不同的峰值电流密度。结果表明，峰值电流密度增加所导致的应力降低与温度无关。应变硬化系数也呈现出类似的趋势。由于电流聚集效应，断裂应变呈现出最佳值。
