This paper is concerned with the hardening behavior of 4340 steel at ultra-high strain rates from 104 s1 to 106 s1. Tension tests were conducted using Instron 5583, HSMTM, and SHPB testing machines at a wide range of strain rates from 103 s1 to 103 s1. Three different impact velocities were performed for the Taylor impact tests to evaluate the reliability of Johnson–Cook model, modified Johnson–Cook model, modified Khan–Huang model, and Lim–Huh model at ultra- high strain rates for 4340 steel.
