“…According to previous studies, possible mechanisms for the creation of a crater are (a) bombardment of the melted surface by the accelerator elements (a technological factor) [12,13]; (b) formation of pores in the surface layer of the sample due to casting [13]; and (c) instability in the physical and chemical states of the irradiated surface [7,12,[21][22][23][24], including differences in phase and chemical composition, impurity distribution, and dislocation density of targets. Few other studies have also suggested filamentation of the ion beam in the pulse [10] and formation of a gas-plasma phase during the ablation of surface volatiles [12] as possible mechanisms for the creation of craters.…”

“…As an increase in the ion dose, this led to increase the amorphous lattice site in terms of crater formation. 21 Crater can be observed at the central part of the Figure 2C, and nickel concentration was present in the form of patches at the ridges of that crater. Small particles were present inside the crater can be seen in subsize figure (c).…”

Funding information Higher Education Commission of PakistanIn this study, nickel ions were implanted in brass at 2.0-MeV energy doses ranging from 1.9 × 10 14 , 4.8 × 10 14 , and 1.0 × 10 15 ions cm −2 at room temperature. Formation of micro size particle cluster, crater, void, rust, and flower-like structure were observed in scanning electron microscope (SEM) micrographs. XRD patterns explain the plane (1 1 1) and plane (2 2 0) under abrupt fluctuations, but in plane (2 0 0), systematic changes occur after ion implantation. Modifications in crystallite size, lattice strain, and dislocation density were discussed. In all the implanted specimens, values of hardness were smaller as compared with the unimplanted one.Precise changes occurred in the value of d-spacing that produced alteration in electrical conductivity at the initial ion doses. Therefore, electrical conductivity values were changed from 3.980E 6 (S/m) to 2.966E 7 (S/m). Further increment in the ion dose, electrical conductivity reduced to recover its value. Initial trend of hardness and electrical conductivity was nonlinear, but both tend to recuperate their values in the end. In FT-IR spectra, three new bands were formed at 1261, 1417, and 1455 cm −1 after ion implantation that was due to change in bonding of brass.

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..
