High-current pulsed electron-beam (HCPEB) surface modification of Al-Co-Cr-Fe-Ni high-entropy alloy (wt. %) Al—15.64; Co—7.78; Cr—8.87; Fe—22.31; Ni—44.57, fabricated via wire-arc additive manufacturing was studied. The initial condition the sample is characterized by a highly inhomogeneous distribution chemical elements that form alloy. samples were irradiated with different electron beam ener...

Interdiffusion coefficients of the refractory elements in Fe-Cr-X (X 1⁄4 Mo, W) and Fe-Mo-W ternary alloys were measured on the basis of the modified Boltzmann-Matano method for ternary systems. The cross interdiffusion coefficient, ~ D CrW was positive in Fe-Cr-W ternary alloy, indicating that W accelerates interdiffusion between Fe and Cr atoms. On the other hand, the cross interdiffusion coe...

Average effective interdiffusion coefficients of individual components and tracer diffusion coefficient Ni were experimentally determined in FCC CoCrFeNi high entropy alloys. elements alloys using the Dayananda-Sohn approach. Cr had highest while lowest magnitude average alloy. The was without application radiotracers novel analytical method proposed by Belova et al. based on linear response th...

We present high resolution, high SNR spectra of the QSO Q2206-199 obtained with HIRES on the 10m W.M. Keck Telescope. Our analysis focuses on the two previously identified damped Lyα systems found at z = 1.920 and z = 2.076. For the z = 1.920 system, we measure accurate abundances (relative to solar) for Fe, Cr Si, Ni, Ti, and Zn: [Fe/H] = −0.705 ± 0.097, [Cr/H] = −0.580 ± 0.100, [Si/H] = −0.40...
