| dc.description.abstract | The Ti6Al4V structures in aircraft and biomedical industries are usually exposed to quasistatic
loads. Therefore, understanding the quasi-static behaviour of this alloy manufactured by
an additive manufacturing process is paramount. This paper documents an investigation of the
quasi-static mechanical properties of various microstructures of heat-treated Ti6Al4V(ELI) parts
manufactured by laser powder bed fusion (LPBF). The effects of different quasi-static strain rates on
different microstructures of these samples and their strain hardening are also presented. The test
samples were produced using an EOSINT M280 direct metal laser sintering (DMLS) machine and,
thereafter, subdivided into three major groups, namely samples C, D and E, for high-temperature
annealing at different heat treatment strategies. A universal hydraulic testing machine (UTM) was
used to carry out tests at strain rates of 0.001 s1, 0.005 s1 and 0.1 s1. The three forms of LPBF
Ti6Al4V(ELI) were found to be sensitive to quasi-static strain rate, whereby values of yield and flow
stresses in each form of alloy increased with increasing strain rate. The order of the strength at each
strain rate from the highest to the lowest was found to be samples C, D and E. The effects of strain
rate on flow hardening were found to be significant in samples C and insignificant in samples D
and E. | en_US |
