Tensile properties of heat-treated AISI4340 steel with a thickness of 1 mm were evaluated at various strain rates ranging from 0.001 s1 to 1400 s1 using Instron 5583, a high-speed material testing machine (HSMTM), and split Hopkinson pressure bar (SHPB) testing machine. The specimens for the tests were directly fabricated from the heat-treated projectiles made of AISI 4340 steel. Slack type jig system was utilized for the tests of the intermediate strain rate ranging from 0.1 s1 to 100 s1 to release load ringing phenomenon. Two dimensional digital image correlation (2D-DIC) method was employed to evaluate the strain distribution in the gauge section during tests. The heat-treated AISI4340 steel shows high strain-rate sensitivity in terms of the flow stress and strain hardening. These measures increase as the tensile strain rate increases. The dynamic tensile properties of the heat-treated AISI4340 steel are also compared with those of AISI4340 steel. The flow stress of the heat-treated AISI4340 steel is relatively high compared to that of AISI4340 steel in the entire range of the strain rates.
