High-rate deformation of single crystal tantalum: Temperature dependence and latent hardening
- Univ. of California, San Diego, La Jolla, CA (United States). Center of Excellence for Advanced Materials
Latent hardening is defined as the hardening on a secondary slip system caused by slip on a primary slip system. Latent hardening is usually quantified by a latent hardening ratio (LHR) = {tau}{sub s}/{tau}{sub p}, where {tau}{sub p} is the shear stress on the primary system just before unloading, and {tau}{sub s} is the yield shear stress on the secondary system. The aim of the present research was to experimentally determine the LHR on the {l_brace}211{r_brace} {l_angle}111{r_angle} slip systems of single-crystal tantalum during dynamic deformation. The temperature dependence of the {l_brace}110{r_brace} and {l_brace}211{r_brace} slip planes at these high strain rates was also determined.
