The defining feature of high-entropy alloys (HEAs) is their unprecedented degree compositional inhomogeneity which influences dislocation movements. We demonstrate differences between a HEA (Fe 40 Mn Co 10 Cr ) and conventional solution alloy (316L stainless steel) using acoustic emission (AE) spectroscopy. AE measurements under tension show the coexistence two avalanche processes in Fe HEA, wh...

Abstract Ni-Ti-Cu alloy can not only prevent scale and biological adhesion, but also has applications in aerospace, automotive engineering, nanotechnology. In this study, Ni 50 Ti 40 Cu 10 45 15 large-size thin-walled parts are prepared on the surface of plates using laser additive manufacturing technology. The optimum operational parameters explored through a two-factor controlled variable met...

The paper reveals the influence of Li, B and composition metal contacts on processes resistive switching in memristive structures M/NC/D/M. After field exposure Cu/(Co50Fe50)Х(LiNbO3)100-Х/s-LiNbO3/Cu/sitall, Cu/(Co50Fe50)Х(LiNbO3)100-Х/d-LiNbO3/Cu/sitall Cu/(Co40Fe40B20)Х(SiO2)100-Х/d-LiNbO3/Cu/sitall at x < 13 at.% was detected a residual voltage (up to 16 mV) due electromigration Li ions,...
