Effect of heat treatment on stability of impact-induced adiabatic shear bands in 4340 steel

Adiabatic shear bands (ASBs) have been observed in many engineering applications, including armor plates and metal working operations subjected to both high strain rates (>103S−1) and large strains. These bands indicate excessive deformations due to strain localization. Preventing their formation by proper choice of materials or eliminating them when formed may avert the occurrence of catastrophic failures. In this study, impacted specimens of …
