Advanced Functional Materials, EarlyView.The electroplating of a CrCoNi medium‐entropy alloy is achieved using a mixture of an ionic liquid and an aqueous solution containing metal salts. The CrCoNi medium‐entropy alloy thin film exhibits high wear and corrosion resistance superior to conventional hard chromium coatings. Abstract High‐entropy alloys (HEAs) and medium‐entropy alloys (MEAs) are

Electron states and magnetic phase diagrams of strongly correlated systems [PDF]
Phys. Met. Metallogr., Vol. 119, No. 13, pp. 1267-1271 (2018), 2019 Various auxiliary-particle approaches to treat electron correlations in many-electron models are analyzed. Applications to copper-oxide layered systems are discussed. The ground-state magnetic phase diagrams are considered within the Hubbard and $s$-$d$ exchange (Kondo) models for square and simple cubic lattices vs.

Materials and Corrosion, EarlyView.The austenitic stainless steel AISI 316 L was ground using industrially common grinding belts to investigate the corrosion resistance of the resulting surfaces. Although all grinding belts produced comparable ground surfaces, differences in corrosion resistance were detected. The cause of the local corrosion susceptibility was identified and quantified

Modern Physics of the Condensed State: Strong Correlations and Quantum Topology [PDF]
Physics of Metals and Metallography, Volume 120, Issue 6, pp.
513-548 (2019), 2019 The topic of the review is the application of new ideas of unconventional quantum states to the physics of condensed matter, in particular of solid state, in the context of modern field theory. A comparison is made with classical papers on many-electron theory, including the formalism of many-electron operators.

Materialwissenschaft und Werkstofftechnik, EarlyView.Hot tensile testing of low carbon microalloyed steel at 650 °C–1100 °C and strain rates of 10−2 s−1 and 10−3 s−1 revealed a ductility minimum at 700 °C–850 °C. Thick ferrite films at <700 °C led to ductile fracture, while thinner films in the 700 °C–850 °C range caused brittle intergranular fracture.
