Advanced Functional Materials, EarlyView.Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

Advanced Functional Materials, EarlyView.Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Progress in Structural Engineering and Materials, 1997
AbstractIn recent decades, the ductility and weldability of structural steels has improved considerably. Also, the developments in modern welding technology have led to a decrease in the fabrication costs of steel structures, especially when higher strength steels are used. This has created new opportunities for more economical applications of steel in

Metal Science and Heat Treatment, 1998
Steels have found wide application in modern aircraft and are the profile materials in some structures. They are used when a high specific strength, rigidity, fatigue limit, and high-temperature strength are required, for example, in the production of wing bars, longerons, ribs, landing gear parts, and gear transmission mechanisms.

1. In steels with 0.25–0.35% C and 10–14% Ni the mechanical properties after quenching (cooling in air) are approximately the same as for carbon-free maraging steels: σb=190−200 kg/mm2; δ=10–12%; ψ=45–50%;an=6–7 kg-m/cm2;ap=1.7–2.2 kg-m/cm2. Small cold plastic deformation (2–5%) substantially increases the strength characteristics: ΔσT=50−60 kg/mm2,

Favourable Steel Structures using High Strength Steels
ce/papers, 2021AbstractAs a part of the European RFCS‐project STROBE, HOCHTIEF Engineering has developed a calculation programme as the basis of a web‐tool for the design and optimization of steel beams. The programme is suitable for steel girders of normal strength and for high strength girders up to S690 including welded hybrid girders. In this paper, the developed

High strength austenitic steels
Metal Science and Heat Treatment of Metals, 1959‘Transitional’ steels have an unusual combination of mechanical properties. They may have a low yield stress (20–40 kg/sq. mm=28, 400–56, 900 psi) and a high tensile strength (100–200 kg/sq mm=142, 000–284, 000 psi). The mechanical properties of these steels depend mainly on the extent to which austenite decomposes into martensite in deformation, and ...

High-Strength, Low-Alloy Steels
Science, 1980High-strength, low-alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load-bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium,
