This paper is concerned with the hardening behavior of 4340 steel at ultra-high strain rates from 104 s1 to 106 s1. Tension tests were conducted using Instron 5583, HSMTM, and SHPB testing machines at a wide range of strain rates from 103 s1 to 103 s1. 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.
