| Abstract Scope |
Structural materials for next-generation applications need to endure increasingly demanding conditions, including coupled high temperatures and mechanical loading. Nanoindentation can complement bulk scale data by providing a highly localized response, but combining high strain rate and high temperature has been a bigger challenge comparatively at the small scale. Recent advances in instrumentation have allowed Berkovich nanoindentation at strain rates of >100 1/s while at high temperatures, which will be presented here. The behavior of tungsten, which was used as a model system since it is frequently employed as a refractory material, will be explored in terms of its high strain rate behavior, the temperature dependence of the mechanical behavior and its strain rate sensitivity. Changes in material properties with strain rate and temperature will be discussed, as well as challenges and outlooks on the applications of the technique. |
