Abstract

In this research we investigate different metallurgical effects, such as: inclusions and hydrogen (H) on the dynamic strength of different metals. We also investigate the deformation mechanism evolved from inclusions by metallurgical analysis. The dynamic loading was produced by accelerating Al or steel impactors in a gas gun into different targets (uniaxial plate impact experiments) at a velocity range of 330 to 430 m/s. After impact, the hydrogen-lean duplex stainless steel (HLDS) system represents the same failure mechanism as in the lower strain rates; increasing strength and decreasing ductility. The Al-Ta and Al-B systems indicate different failure mechanisms compared with the ultra-pure (UP) Al. In addition, the failure mechanism was different when the Ta amount in the Al matrix was higher. Our results show that small amount of inclusions have the same effect on the Al matrix. However, differences can be seen when Ta amount is higher, as opposed to previously published work in the literature.
