“…However, hydrogen pipelines are not solely composed of a single metal. The doping of alloying elements such as Cr, Mn, Ni, and Mo in steel materials can improve the chemical and mechanical properties of the steel [38][39][40][41][42]. Extensive research has been conducted on the impact of these alloying elements on the mechanical properties of metals, with most studies examining their effects at the macroscopic level.…”

Based on first principles density functional theory (DFT) methods, this study employed the Cambridge Serial Total Energy Package (CASTEP) module within Materials Studio (MS) software under the generalized gradient approximation to investigate the adsorption, diffusion behavior, and electronic properties of hydrogen atoms on α-Fe(110) and α-Fe(110)-Me (Mn, Cr, Ni, Mo) surfaces, including calculations of their adsorption energies and density of states (DOS). The results demonstrated that doping with alloy atoms Me increased the physical adsorption energy of H2 molecules on the surface. Specifically, Mo doping elevated the adsorption energy from −1.00825 eV to −0.70226 eV, with the largest relative change being 30.35%. After doping with Me, the chemical adsorption energy of two hydrogen atoms does not change significantly, among which doping with Cr results in a decrease in the chemical adsorption energy. Building on this, further analysis of the chemical adsorption of single atoms on the surface was conducted. By comparing the adsorption energy and the bond length between a hydrogen atom and iron/dopant metal atom, it was found that Mo doping has the greatest impact, increasing the bond length by 58.58%. Analysis of the DOS functions under different doping conditions validated the interaction between different alloy elements and H atoms. Simultaneously, simulations were carried out on the energy barrier crossed by H atoms diffusing into the metal interior. The results indicate that Ni doping facilitates the diffusion of H atoms, while Cr, Mn, and Mo hinder their diffusion, with Mo having the most significant effect, where its barrier is 21.88 times that of the undoped surface. This conclusion offers deep insights into the impact of different doping elements on hydrogen adsorption and diffusion, aiding in the design of materials resistant to hydrogen embrittlement.

“…The recycling and production of secondary zinc alloys accounts for 30% of the global zinc consumption. The level of recycling is increasing in line with advances in zinc production and zinc recycling technologies [4][5][6]. Zinc is most often used as a coating element or as an alloying element.…”

One of the main objectives in order to increase economic efficiency in foundries is to determine the ratio of the scrap material which can be used in the further manufacture. This factor is important for determining the final prices of products and their competitiveness, given that the prices of zinc on world markets have increased significantly in the recent years. This article deals with the possibilities of remelting the zinc foundry alloy ZnAl4Cu3 and also evaluates the effect of cadmium on selected properties. The main goal is to provide a comprehensive view of the influence of these two factors on selected mechanical properties, casting properties, and microstructure. An important part of the research is to point out the combined influence of given factors. The results of experiments confirmed that an addition of 3 wt.% of Cd has a significant impact on technological and mechanical properties. Fluidity values compared to the Cd-free alloy increased by 22.4%. In terms of mechanical properties, the influence of Cd on the tensile strength was most visible, with a decrease in average by 25 MPa.
