| dc.description.abstract | This study documents an investigation of the flow stress properties and microstructural
features of Ti6Al4V (ELI) alloy produced using laser powder bed fusion (LPBF). Selected heat
treatment strategies were applied to the material to obtain different microstructures. The influence of
quasi-static strain rates and temperature on the obtained microstructures of this material and their
strain hardening properties are documented in this study. All microstructures of the alloy formed
in this study were found to be sensitive to quasi-static strain rates and temperatures, where their
flow stresses increased with increasing strain rate and decreased for tests conducted at elevated
temperatures. The strain hardening rates of the fine microstructures were found to be high compared
to those of coarse microstructures. The strain hardening rates for the various forms of LPBF Ti6Al4V
(ELI) examined here were found to diminish with increasing test temperature. Though the deformed
surfaces of the built samples were largely dominated by adiabatic shear bands (ASBs), the absence of
ASBs was noted for all samples tested at a temperature of 500 ◦C and an imposed strain of 30%. | en_US |
