Abstract

The plastic deformation of a commercial grade low carbon steel has been investigated using microhardness and grain strain measurement techniques. Two distinct modes of deformation during plastic flow in low carbon ferritic steel have been identified. The initial stage involves the propagation of the Luder's band along the gauge length of the sample by slip strain in the surface and near surface grains only, the strain accommodation in the interior of the material being attained by a predominantly grain translation mode. The second stage involves the propagation of a strain hardening front through the cross-section of the material as the macro-strain is increased through the flow stress region.
