In order to study the effect of initial microstructures on the hot deformation behavior and workability of Ti 2 AlNb alloy, the isothermal compression experiments of as-rolled and solutiontreated Ti-19Al-23Nb-0.5Mo alloys were conducted in the temperature range of 900-1100 • C and strain rate range of 0.001-10 s −1. Subsequently, the processing maps of different state materials were established based on dynamic material model (DMM) and Prasad's instability criterion. The suitable regions for hot working were determined in the processing maps, which was verified through high-temperature tensile test. The results show that although the solution-treatment could be used to improve the ductility of as-rolled Ti 2 AlNb alloy at room temperature, the as-rolled microstructure exhibited better hot workability at high temperature compared to the solution-treated microstructure.

“…Conversely, laser-driven protons can offer many opportunities in this field 13 , in particular when benefitting from their high particle flux that provides ideal conditions for performing and analyzing stress tests on different materials that are exposed to high-energy fluence, i.e., harsh conditions. Examples of these conditions can be found in high-energy density physics, astrophysics, aero spatial applications, or energy production 14 (nuclear plants, but also upcoming facilities for inertial or magnetic confinement fusion (ICF-MCF) 15 in particular for their plasma-facing materials (PFM) 16 – 18 ). Currently, three stress test methods are the most commonly employed.…”

Laser-driven particle acceleration, obtained by irradiation of a solid target using an ultra-intense (I > 1018 W/cm2) short-pulse (duration <1 ps) laser, is a growing field of interest, in particular for its manifold potential applications in different domains. Here, we provide experimental evidence that laser-generated particles, in particular protons, can be used for stress testing materials and are particularly suited for identifying materials to be used in harsh conditions. We show that these laser-generated protons can produce, in a very short time scale, a strong mechanical and thermal damage, that, given the short irradiation time, does not allow for recovery of the material. We confirm this by analyzing changes in the mechanical, optical, electrical, and morphological properties of five materials of interest to be used in harsh conditions.
