电塑性效应及其应用

评述显示电塑性效应的最早实验，电塑性研究的新近信息和电塑性技术的应用前景。利用高密度电流脉冲剌激导致的电塑性现象，是一种综合物理效应，它主要由电子对位错的有效推动作用引起，焦尔热效应、磁压缩效应、电流集肤效应、电子润滑剂效应起辅助作用。与传统拔丝工艺比较，电塑性拔丝显著降低掺制力，增大金属的塑性，改进丝的质量和性能，减免中间退火，强化生产，提高生产力，节约能源，改善生态环境，是一种有发展前途的新的

Electroplasticity and Its Applications

The prime experiments first show-ing the electroplastic effect, the latest informa-tion concerning studies on electroplasticity andthe application prospects of electroplastic tech-nologies were briefly reviewed. Theoretically,electroplasticity resulting from the stimulationby high density electric current pulses is a conse-quence of combined physical effects, it stems ba-sically from an active electron push on movingdislocations during plastic flow and the Jouleheating. pinch, skin and electron lubrication ef-fects just play a supplementary role. Comparedwith the traditional wire drawing, electroplasticone can lead to reducing drawing force, enhanc-ing metal's plasticity, advancing wire's qualityand properties, diminishing or eliminating pro-cess annealing, intensifying production, raisingproductivity, economizing on electricity, improv-ing ecological conditions,and so,is a prospective-ly new wire drawing technology.
