Abstract

This study deals with the mechanical properties of two kinds of structural sintered steels under a wide range of strain rate between 10^-4 and 10³s^-1. The split-Hopkinson pressure bar (SHPB) technique was used for dynamic tensile tests at the strain rates greater than 10²s^-1. The stress-strain relations were experimentally determined, and the tensile strength has been mainly discussed with respect to strain rate and relative density.
