Heterostructure effect at the interface of maraging steel deposited upon carbon steel via directed energy deposition

Maraging steel was deposited on S45C carbon steel via directed energy deposition to investigate the mechanical behaviour of the interface region where dissimilar metals are deposited by additive manufacturing process. Due to the mechanical incompatibility between each region of the layered structure, the synergetic heterostructure effect of the layered structure was attributed to the formation of strain gradient and back stress strengthening effect. The new study found that the mechanical interaction of domains in the interface region, as well as the residual stress field distribution, should be precisely monitored in order to enhance the interface region's mechanical stability.

A Comparison of Low-Temperature Deformation Behavior and Fracture in Low-Carbon Steel Specimens Obtained by Electron Beam Additive Manufacturing and Conventional Casting and Normalization

The microstructure, phase composition, and temperature dependence of low-carbon steel produced by conventional casting and electron beam additive manufacturing have been investigated in the present study. A decrease in test temperature from 300 K to 77 K leads to a change in the steel's fracture micromechanism from a dimple fracture to a cleavage one.

Finite Element Modeling of Hot Rolling of 1075 Carbon Steel Process with Variable Cross Section

Currently, it is common to use steel poles for livestock and agriculture applications. The steel industry in Mexico imports products from other countries or companies that specialize in metallurgy at unreasonable price. Given a varied cross section railway profile, SFTC DEFORM-3D software was used to model five hot rolling passes.

The corrosion inhibition of carbon steel in 1 M HCl solution by Oestrus ovis larvae extract as a new bio–inhibitor

In this study, the corrosion behavior of carbon steel in the HCl solution was investigated because, nowadays, using the eco-friendly and economic corrosion inhibitors in various industries is a challenge. The Tafel polarization's results revealed that the inhibition sensitivity was about 56% with the highest value at a concentration of 1 g/L. Sample properties changed according to the proposed electrical circuit, according to the electrochemical impedance spectroscopy findings, with the indicated concentration of bio-inhibitor.

Corrosion rate and corrosion behaviour analysis of carbon steel pipe at constant condensed fluid

This report investigates the corrosion rate and deterioration behavior of carbon steel pipe in the presence of a constant condensed fluid from a geothermal power plant. During the immersion period, where water quality parameters are constant, the corrosion rate in the liquid portion of the condensate fluids remains stable, according to the results. In the meantime, the corrosion rate of low carbon steel pipe pipes decreases, but with the longer exposure time of the condensate fluid, it may become less effective. During immersion tests determined in the corrosion test, the corrosion products were found to be uniform with iron oxide in the form of FeO and Fe2O3*H2O.

Effect of molybdenum addition on microstructure and mechanical properties of plain carbon steel weld

The present investigation focuses on two key areas: the first is to determine the mechanical properties of weld joint alloying with different amounts of molybdenum, with the second being the optimization of welding process parameters of submerged arc welding using Taguchi philosophy. Using multiple regression analysis for the new base metal plate geometry, a mathematical relationship between bead width, arc voltage, and welding speed was also found.

Electrochemical Corrosion of Low Carbon Steel in a Hydrochloric Acid Medium

In a HCl solution, BPTU appears to be a good anodic inhibitor for low carbon steel. The results obtained by the Tafel extrapolation and linear polarization techniques for the degradation of mild steel in HCl medium were in good agreement, according to the investigation. In the present study, the effect of temperature and BPTU concentrations on low carbon steel corrosion is also investigated.

Ionic liquids as corrosion inhibitors for carbon steel protection in hydrochloric acid solution: A first review

Carbon steel is one of the most widely used metallic alloy and widely used in extreme industrial conditions, especially in the extraction and processing of oil/gas, making this alloy particularly vulnerable to corrosion. To maintain carbon steel in such condition, the use of corrosion inhibitors is essential. Conventional corrosion inhibitors have been the primary method to minimize the corrosive effect on carbon steel for decades. In this first review, the authors used ionic liquids as corrosion inhibitors for carbon steel in hydrochloric acid, with significant developments reported in recent literature.

Sodium Succinate as a Corrosion Inhibitor for Carbon Steel Rebars in Simulated Concrete Pore Solution

In 0. 6 M Cl u2212 simulated concrete pore solution, sodium succinate was tested as an organic corrosion inhibitor for carbon steel rebars. The investigated corrosion inhibitor had a good corrosion inhibiting result as it adsorbs on the surface of the rebar, producing a waterproof adsorption film. The PDP tests were verified by EIS, showing that sodium succinate displaces the water molecules at the interface, resulting in an adsorption film by complicateding with ferrous ions. The film thickness was determined, and sodium succinate was able to produce a thicker protective film relative to the reference film at every temperature. The adsorption of sodium succinate by Temkin isotherm. The delocalized electrons in the carboxyl group were also highly HOMO energies and electrostatic potential, which allows the absorption of sodium succinate corrosion inhibitor onto the carbon steel rebar surface, which facilitates quantum chemical analysis.
