“…Based on Eqs. [1] through [4], the magnitude of retardation of a certain kind of solute at given temperatures is associated with the bulk concentration of the solute and the size mismatch between the solute and the Fe atoms. A higher concentration and a higher size mismatch give rise to a higher E esc , thus the dislocation velocity and subgrain boundary migration will be more suppressed.…”

“…The effect of impurities has been investigated in a hot-rolled low-carbon steel with regard to microstructure, but also effect of residuals on transformation kinetics and grain size, and hence mechanical properties. [4] Low-carbon formable steels are primarily used for drawing applications. Good drawability requires a high degree of true strain in the planar direction and good resistance to plastic flow in the thickness direction; meanwhile the planar anisotropy should be low to reduce the extent of earing.…”

Impurities (Cu, Sn, Cr, and Ni) have been added to a low-carbon formable strip steel to simulate the scenario of increased use of scrap during steel production. Texture evolution during annealing of the cold-rolled base steel and impurity-added steel have been investigated. The impurities were shown to suppress the development of the γ-fiber texture. Meanwhile, a higher fraction of random orientations was developed in the impurity-added steel. However, the adverse effect of impurities on the γ-fiber was mitigated during annealing at higher temperatures (650 °C to 750 °C). The correlation between texture development and microstructure heterogeneity, and the effect of impurity additions on texture development are discussed. This work provides guidelines on recycling scrap for the production of low-carbon formable steels.

“…Structural defects affect the reflection angle and enhance absorption opportunities, thereby increasing the shielding effectiveness . Impurities derived from natural materials can be used to fine-tune important effects that favor new properties, such as changes in crystallite size, crystal shape, and thermodynamic properties, , and the selection of materials from nature makes composites an environmentally friendly material during or after use. Therefore, we combine NS with natural materials, such as iron sand (IS) and laterite soil (LS), using the milling method , to form NS/IS and NS/LS nanocomposites.…”

Efforts to produce microwave absorber materials that are inexpensive and environmentally friendly have become a means of greening the environment. The breakthrough can be focused on industrial waste and natural materials for functional purposes and how to enhance their performance. We successfully synthesized nickel slag/laterite soil (NS/LS) and nickel slag/iron sand (NS/IS) nanocomposites using a simple mechanical alloying technique, and the electromagnetic (EM) wave absorption capacities of the nanocomposites were measured using a vector network analyzer. The structural properties of the nanocomposites were analyzed by X-ray diffraction spectroscopy, where the results of the analysis showed that NS/IS has the largest crystallite size (15.69 nm) and the highest EM wave absorption performance. The optical properties of the nanocomposites were determined from their Fourier transform infrared spectra using the Kramers–Kronig relation. As determined through a quantitative analysis of the optical properties, the distance between the longitudinal and transversal optical phonon wavenumber positions (Δ(LO – TO) = 65 cm–1) is inversely proportional to the reflection loss. The surface morphologies of the nanocomposites were analyzed by scanning electron microscopy, and the particle diameters were observed by binary image and Gaussian distribution analyses. The nanocomposite surface exhibits a graded-like morphology, which indicates multiple reflections of the EM radiation, consequently reducing the EM interference. The best nanocomposite for an attenuated EM wave achieved a reflection loss of −39.14 dB at 5–8 GHz. A low penetration depth has implications for the electrical charge tuning of the storage and composite magnets. Finally, the EM absorption properties of NS/IS and NS/LS indicate a 2-mm-thick environmentally friendly nanocomposite for EM absorption.

“…Sn had an obvious effect on low-temperature impact properties of 1.5Mn-Mo cast steel, resulting in a marked rise of the fracture appearance transition temperature (FATT) when the Sn content was increased from 0.05-0.10% [15]. Furthermore, increasing the Sn content can slightly increase tensile strength but lower room-temperature fracture toughness as well as tensile ductility [15][16][17]. However, the current control processes for residual tin in steel are not satisfactory, and tin removal from steel cannot be achieved by conventional processes [18].…”

The intercritical heat treatment process is considered a novel technology to solve the mismatch of strength and toughness of low alloy steel containing residual elements. In the present study, the effects of initial microstructure and intercritical quenching temperature on microstructural morphology, mechanical properties and fracture appearance of the experimental tin-bearing steel have been investigated. The results show that, under the same intercritical quenching and tempering (IQ-T) heat treatment parameters, the initial microstructures of bainite and ferrite (B-F) and complete martensite (M) yield different ferrite morphologies, block and strip-like ferrite, respectively. It is found that after IQ-T process, the tensile strength of the steel containing 0.09% tin with B-F as initial microstructure is 1061 MPa, but the impact energy value is only 26 J; while the steel with M has achieved the combined properties of high strength and excellent toughness, and the optimal intercritical quenching temperature is 770°C.
