Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy
The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.

Static analysis of the vibration protection mechanism of the human operator seat of a ground machine [PDF]
Ground transport and technological machines are being improved, which leads to an increase in their power, speed, vibrations and impacts. Vibrations have a negative effect on the technical condition of the machine, health and performance of the operator.

Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Effect of propeller phase angles on the vibration response of a twin-screw super-yacht
Propeller-induced hull excitation is one of the most important causes of the vibration levels experienced in the habitable decks of ships. A reliable assessment of on-board vibrations during the early stage of ship design requires the development of ...

Controlling vibration propagation in a thin beam using a neutraliser
This paper is concerned with the control of vibration transmission along a thin beam using a vibration neutraliser. The analysis focuses on the case where the position of the neutraliser is constrained such that it cannot be at the source or the receiver,
