Abstract
With the objective of establishing the effects of the metallurgical condition on the propensity to form adiabatic shear bands, low-carbon steels (AISI 1018 and 8620) having widely different temperability responses were subjected to impact by cylindrical projectiles in the velocity range of 450 to 1050 m/s. These steels received a variety of mechanical and thermal treatments that provided a wide range of microstructures and mechanical responses. The propensity for shear band formation was strongly dependent on the mechanical response. It was measured by counting the length of shear bands per cross section. Microstructural characterization of the bands revealed that white-etching bands were only observed in the quenched and quenched-and-tempered conditions.
