“…P is the source term, and k is the energy density, d(x) is the distribution function of ion beam energy with depth, which was calculated by SRIM. The current density evolution function with time is given by f(t), and its evolution of the TEMP-4M device was taken from the paper [43]. Both f(t) and d(x) are normalized functions.…”

In recent years, high entropy alloys (HEAs) have attracted significant attention due to their excellent physical, chemical, mechanical properties, and good irradiation resistance, thus are considered as potential candidates for fission and fusion structural applications. CoCrFeMnNi HEA was irradiated by high intensity pulsed ion beam (HIPIB) to investigate the effects of thermal shock irradiation on its microstructure, surface morphology and mechanical properties. It was found that CoCrFeMnNi HEA maintained the face-centered cubic single-phase structure after HIPIB irradiation. The ion beam effect of irradiation produced numerous defects such as vacancies and stacking faults within the range of carbon ions. While the thermal effect reduced vacancy concentration beyond the ion range by promoting the recombination of vacancies with interstitials, and decreased the nano-hardness of CoCrFeMnNi HEA. The thermal effect and shock wave effect promoted the migration of vacancies and formed defects such as stacking faults etc. far beyond the ion range in CoCrFeMnNi HEA. Because of the very compositional complexity, the high-level chemical disorder and local lattice distortion of CoCrFeMnNi HEA, the lattice parameter was almost unchanged after HIPIB irradiation. Even if the temperature reached the melting point of CoCrFeMnNi HEA, there was no crack on the surface after surface remelting and rapid cooling. CoCrFeMnNi HEA showed good thermal stability and thermal shock irradiation resistance..

“…Intense pulsed ion beam (IPIB), invented as ignition technique for inertial confinement fusion (ICF) [1], has been intensively researched for various applications such as nanopowder synthesis [2,3], film deposition [4,5], surface modification [6,7] and simulation of high thermal load for nuclear fusion [8]. When IPIB with high-power density bombard on material, a fast temperature rise and decline are induced in the near-surface region of material, giving rise to melting, evaporation, and re-solidification.…”

Intense pulsed ion beam (IPIB), featured with pulsed high-power density, has been widely used in the modification of materials. The influence of IPIB irradiation on surface microstructure and phase structure of (TiZrNbTaCr)C ceramics was investigated in this work. Experiments were carried out using TEMP-4M accelerator with peak accelerating voltage, current density, and pulse duration (FWHM) of 220 kV, 150 A/cm2, and 80 ns respectively. Atomic force microscope (AFM), scanning electron microscope and Energy-dispersive X-ray spectroscopy (SEM-EDS), as well as X-ray diffraction (XRD) were used to analyze the surface microstructure and phase structure of (TiZrNbTaCr)C ceramics under IPIB irradiation. The AFM and SEM images showed that the grain size of (TiZrNbTaCr)C increased, and the size and quantity of holes decreased after IPIB irradiation which might improve the erosion resistance of material. After IPIB irradiation, the segregation of Cr and Ta elements were observed by EDS measurement. The phase structure stability of samples under IPIB irradiation was confirmed by XRD and the lattice parameters and crystal spacing was discussed as well.
