摘要：

Measurement of electrical resistivity is an appropriate method for estimating dislocation densities even at high deformation. The findings were: (below 40% reduction): steep increase of resistivity; (40% - 98% reduction): linear increase of resistivity; (above 98% reduction): no further increase of resistivity, saturation. Reductions of 98. 6% and 99. 4% mean nominal strains of 7000% and 16000%.
