his study investigates the effect of room temperature deformation on the
microstructural behavior of Ti6Al4V alloy. To study this, room temperature
uniaxial compression test was carried out at low strain rate of 0.01 s
-1
with
increase in 5% stepwise degree of deformation up to fracture. At each
stage of the deformation, stress strain curve was correlated with change in
microstructure and grain orientation. Microstructural evolution and grain
orientations are mapped at each stage of deformation with the help of electron
back scattered diffraction (EBSD) and optical microscopy. Fracture of material
occurs within 30% of deformation and exhibit grain refinement. Flow stress
increases with increase in deformation and indexed in terms of increase in
strain hardening exponent and hardness. EBSD mapping and microstructural
analysis confirms Alpha phase fragmentation and grain size reduction.
Deformed sample exhibit basal texture with increasing deformation.
