Abstract

The effect of tensile strain rate on the formation of voids by using the industrial pure iron (0.0028% C,-0.16% Mn,-0.001% Si) with few precipitates was studied. The tensile tests were performed under the initial strain rate of 10-3,101 and 103 s-1. The void distribution, the void spacing and the deformation energy in each strain rate were examined. From these experiments, it was revealed that the energy required for the coalescence of voids was increased with the increase in void spacing and the suppression of void generation by increasing the strain rate improved the local deformation energy.
