This paper is concerned with the effect of deformation twinning on the strain hardening behavior of commercially
pure titanium during the compressive loading. In accordance with many studies on titanium, the
strain hardening behavior of titanium during compression has different characteristics from those of general
metallic materials. It has been reported that the strain hardening rate of titanium during compression can
be divided into three stages. In the first stage, the strain hardening rate decreases as the strain increases
due to dynamic recovery. Following the first stage, however, a sudden increase in the strain hardening rate
is observed in the second stage. It is well known that the occurrence of the second stage is due to the generation
of deformation twinning. After the second stage, the strain hardening rate decreases again as the strain
increases in the third stage. In this paper, a strain hardening model that can represent the three stages of
strain hardening is proposed based on the investigated effect of deformation twinning on the strain hardening
behavior of titanium. The electron backscatter diffraction (EBSD) analyses are conducted to quantify the
twin volume fraction with increase of compressive plastic strain, which provide fundamental frame of the
hardening model for titanium.
