Phys.org  August 7, 2024 A team of international researchers (Stanford University, Lawrence Livermore National Laboratory, Purdue University, Carnegie Mellon University, SLAC National Accelerator Laboratory, Germany) used diffraction patterns from x-ray pulses to investigate the temperature evolution of laser-shocked Al–Zr metal film composites at time delays ranging from 5 to 75 ns driven by a short-pulse laser. They found significant heating of both Al and Zr after shock release. A conventional hydrodynamic model did not fully account for the measured temperature increase, which suggested that other strength-related mechanisms (such as fine-scale void growth) could play an important role in thermal responses under […]
