Materials exposed to ultrashort intense x-ray irradiation experience various damaging conditions depending on the irradiation temperature. A pre-heated target exposed to intense x-rays plays a crucial role in numerous physical-technical systems, ranging from the heavily and repeatedly radiation-loaded optics at x-ray free-electron laser facilities to the inner-most wall of prospective inertial fusion reactors. We study the temperature dependence of damage thresholds in different classes of materials theoretically: an insulator (diamond), a semiconductor (silicon), a metal (tungsten), and an organic polymer (PMMA). The numerical techniques used here enable us to trace the evolution of both the electronic state and the atomic dynamics of the materials. It includes damage mechanisms such as thermal damage, induced by an increased irradiation temperature due to energy transfer from x-ray-excited electrons, and nonthermal phase transitions.
