“…The crystallite size is evaluated for the reflection plane of brass (200) by using Sherrer's formula. 17 Crystallite Size (D) = 0.9 λ FWHMCOSθ (6) Where λ is the X-ray wavelength and its value is 1.542 Å, FWHM is full width half maximum and θ is diffraction angle. The FWHM and diffraction angle are measured in radian.…”

“…This volume can significantly be extended (up till µm ) region than ion implanted region (nm). 17 The second reason for enhancement in the disordered region as compared to ion implanted region is the cascade growth of atomic displacements. By the interaction between Ni ions and host atom of target lattice, the kinetic energy is transferred from ions to host atom in 10 −17 second.…”

“…Furthermore, many works were published describing the implanted ions into the surface of a solid can be modify or change the material's near-surface chemical composition or defect state. 15,16 In the previous work 17 our group has investigated the effect of carbon ions produced by Pelletron accelerator on the brass target. In that work ions of energy 2 MeV with various fluences ranging from 56 × 10 12 to 26 × 10 13 ions.cm −2 were used to modify the properties of brass.…”

“…The ion source, energy as well as dose of ions and consequently the corresponding modifications in brass are entirely different from the previously reported work. 17 The motivation behind the present work is to improve surface, structural and mechanical behavior of brass after self-designed and fabrication laser induced ion source. A nanosecond laser system with, 120 mJ energy, 248 nm wavelength, and 20 ns of pulse duration, has been employed to produce laser induced Ni plasma ions.…”

Laser induced Ni plasma has been employed as source of ion implantation for surface, structural and mechanical properties of brass. Excimer laser (248 nm, 20 ns, 120mJ and 30 Hz) was used for the generation of Ni plasma. Thomson parabola technique was employed to estimate the energy of generated ions using CR39 as a detector. In response to stepwise increase in number of laser pulses from 3000 to 12000, the ion dose varies from 60 × 1013 to 84 × 1016 ions/cm2 with constant energy of 138 KeV. SEM analysis reveals the growth of nano/micro sized cavities, pores, pits, voids and cracks for the ion dose ranging from 60 × 1013 to 70 × 1015 ions/cm2. However, at maximum ion dose of 84 × 1016 ions/cm2 the granular morphology is observed. XRD analysis reveals that new phase of CuZnNi (200) is formed in the brass substrate after ion implantation. However, an anomalous trend in peak intensity, crystallite size, dislocation line density and induced stresses is observed in response to the implantation with various doses. The increase in ion dose causes to decrease the Yield Stress (YS), Ultimate Tensile Strength (UTS) and hardness. However, for the maximum ion dose the highest values of these mechanical properties are achieved. The variations in the mechanical properties are correlated with surface and crystallographical changes of ion implanted brass.
