Special Issue Information

Dear Colleagues,

Metals and alloys are the most important structural materials. The fabrication process determines the microstructure of the material, which in turn determines its corrosion resistance. Corrosion problems occurring on critical infrastructure significantly impact the global economy and the safety of people, with industrial equipment suffering millions of dollars in losses each year due to corrosion-related failures. Surface treatment/ coatings provide a new strategy for corrosion protection. Therefore, we have a Special Issue on “Alloy/Metal/Steel Surface: Fabrication, Structure, and Corrosion”.

We invite you to contribute a paper to this Special Issue. This Special Issue aims to have at least 10 articles, which may be printed in book form if this number is reached.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: metal/alloy fabrication, characterization, surface film/coatings characterization, electrochemistry/corrosion of metal/alloy or surface film/coatings.

We look forward to receiving your contributions.

This article is based on ABAQUS 2022 finite element software to establish a finite element model of the hydraulic forming process of bimetallic composite pipes. The results show that the larger the bulging pressure, the earlier the circumferential elastic deformation of the outer wall of the lining pipe is fully restored during unloading. Under the action of the base pipe, the compression elastic deformation of the lining pipe is greater, and the bonding strength between the base pipe and the lining pipe is higher; as the bulging pressure increases, the rebound amount of the outer wall of the liner slightly decreases, while the rebound amount of the inner wall of the base pipe gradually increases, and the difference in rebound amount between the inner wall of the base pipe and the outer wall of the liner pipe gradually increases; before plastic deformation occurs on the inner wall of the base pipe, its circumferential rebound increases rapidly with the increase in bulging pressure. When plastic deformation occurs on the inner wall of the base pipe, the rate of increase in circumferential rebound decreases; the residual contact stress between the base pipe and the liner increases linearly with the increase in bulging pressure.

The excellent mechanical properties of AISI 201 make it well-suited for applications in industrial components, transportation, and household appliances. However, during machining, this material generates high cutting forces and temperatures, leading to rapid tool wear and high costs. To address this issue, micro-grooves were designed on the rake face in areas prone to thermal and mechanical stress concentration. Through machining experiments focusing on workpiece surface quality, it was found that micro-grooved tools produced superior surface quality, specifically manifested in lower surface roughness, reduced work hardening, and shallower hardened layer depth. Experiments demonstrate that under identical conditions, increasing the cutting speed with tool M reduces the workpiece surface roughness by 0.096 μm to 0.236 μm compared to tool O. Under identical conditions, increasing the feed rate with tool M reduces the workpiece surface roughness by 0.070 μm to 0.236 μm compared to tool O. As cutting speed varies, the absolute surface hardness of workpieces machined by tool M decreases by approximately 39.85 HV, representing a hardness reduction of 14.5%. As feed rate varies, the surface hardness of workpieces machined with tool M is suppressed to a level 10.2%–14.2% lower than that of tool O. As cutting depth varies, the surface hardness of workpieces machined with tool M is suppressed to a level 10.0%–14.7% lower than that of tool O. Additionally, micro-grooved tools demonstrated superior chip curling and breaking performance. This tool design approach, optimized for tool durability and workpiece surface quality, establishes a research foundation for tool design targeting difficult-to-machine materials. Full article

The high hardness and toughness of AISI 4130 alloy present significant challenges during machining, including excessive cutting forces, rapid tool wear, and poor surface finish control. To address these issues, this study combines numerical simulation with turning experiments to systematically investigate the effects of tool geometry and cutting parameters on cutting force, temperature, and surface roughness. Through Deform-3D finite element modeling, one-factor, and orthogonal simulation tests, it was found that the optimal tool geometric combination (λs = 2°, κr = 99°, γ0 = 5°) reduces the cutting forces by 21.86% as compared to the baseline parameters. Experimental validation showed that the agreement between simulated and measured cutting forces was 86.73%–87.8%, with simulated values being 10%–13.27% higher due to idealized boundary conditions. Surface morphological analysis by Bruker Contour Elite K shows that the surface roughness of the workpiece decreases with an increasing cutting speed and increases with an increasing feed rate and depth of cut. The above studies provide a certain research basis for optimizing the tool angle and improving the cutting efficiency. Full article

The corrosion of steel reinforcements substantially degrades the longevity of reinforced concrete structures, particularly in marine settings. This investigation introduces a comprehensive model that simulates the processes involved in moisture and chloride ion transport, rebar corrosion, and the consequent cracking of concrete. The model reveals that the transport dynamics of chloride ions are primarily dictated by their penetration rates through the solution. The sensitivity of the steel to corrosion is a function of the concentrations of water and chloride ions, whereas the rate of corrosion predominantly depends on the availability of oxygen at the corrosive site. Oxygen diffusion is the rate-limiting step in the entire process of the electrochemical reactions of the rebar. And the peak corrosion rates are observed at the interface between the solution and the gas phase. The model calculates the stress and strain in the concrete resulting from volumetric expansion due to oxidization of the steel bars. By accurately reproducing the progression of corrosion-related damage, this model provides crucial insights for predicting the service life of offshore concrete structures and enhancing durability against aggressive environmental conditions.
