This paper is concerned with the effect of deformation twinning on the strain hardening in pure titanium. It is reported
that the strain hardening of titanium during compressive deformation shows uncommon behavior. Generally, strain hardening rate of
metallic materials is decreasing as strain increases. In accordance with many researches for titanium, however, strain hardening
behavior of titanium shows different characteristics from general metallic materials. It is observed that the strain hardening rate of
titanium during compression process can be divided into 3 stages. In first stage, strain hardening rate is decreasing as strain increases.
Following first stage, strain hardening rate is increasing as strain increases in second stage. After second stage, strain hardening rate
is decreasing again as strain increases in third stage. It is well known that the occurrence of the second stage is due to the occurrence
of the deformation twinning. In this paper, the occurrence and the growth of the deformation twinning are observed using EBSD.
Change of twin volume fraction during compressive deformation of titanium is investigated quantitatively. Strain hardening model
which can represent the strain hardening of titanium is also suggested by investigating the effect of deformation twinning on the
strain hardening behavior.
