The transformations during continuous cooling and their effect on the thermoelastic behaviour of β-CuAlBe shape memory alloys have been studied by electrical resistometry, microscopy and differential calorimetry. Under ...

The structural transformations accompanying the low-temperature phase transition (PT) β´→γ in the argyrodite Ag8SnSe6 characterized by mixed electron-ionic conductivity, have been studied using nuclear gamma resonan...

Monte Carlo simulations and finite-size scaling analysis have been carried out to study the critical behavior in a submonolayer lattice-gas, which mimics a nanoporous environment. In this model, one-dimensional chains of...

This study addresses the under-explored dynamic characteristics of unmanned ships in trajectory planning by constructing a constraint space in the navigation state-phase plane. First, we employ a path-velocity decoupling...

The influence of alloy element distributions on austempered ductile iron microstructure and austempering treatment was analysed by a cellular automaton model that considers the ausferritic and martensitic transformations...

The structural and phase composition of boron-rich Fe–В–С alloys in the concentration range of 9.0–16.0 % В, 0.001–1.7 % С, Fe – the balance (in wt. %) was investigated in this work. The cooling rate of the...

Thermodynamic studies on phase transformation of biopolymers in solution are useful to understand their nature and to evaluate their technological potentials. Thermodynamic studies should be conducted avoiding time-relat...

Duplex stainless steels fabricated by Laser Bed Powder Fusion (LPBF) exhibit refined and metastable microstructures that can be particularly sensitive to intermediate-temperature exposure. In this study, the effect of 47...

Abstract Friction Stir Welding (FSW) is the most promising solid-state metals joining method introduced in this era. Compared to the conventional fusion welding methods, this FSW can produce joints with higher mechanical...

With the application of a linear theory of elasticity of anisotropic crystals and the use of experimental values of elastic moduli Сij and compliances Sij given in the Landolt-Börstein tables, characteristic surfaces o...

Problem. The reliability of detachable electrical contact connections is significantly reduced due to an increase in transition electrical resistance caused by thermomechanical deformations, oxidation of contact surfaces...

With the advancement in understanding of the physics inside chaotic systems, chaos has been harnessed from a nuisance to a beneficial factor in optical devices. Light–matter interaction in chaotic systems has been util...

For the Ukrainian industry operating amidst structural transformations, war-related challenges, and resource limitations, innovations constitute not only a source of economic growth but also an important tool for renewal...

This article examines the concept of Generative Engine Optimization (GEO) in the context of the transformations enabled by the integration of generative artificial intelligence into contemporary information search an...

The interactions between the government and the opposition in Ukraine during the Revolution of Dignity (November 2013 – February 2014), a pivotal stage in the development of the contemporary Ukrainian political system,...

The Article is devoted to the substantiation of the key global regularities of the development of the world market of aviation transportation on the basis of a comprehensive generalization of the stages of society’s de...

The shape memory effect in Cu–Al–Ni alloys iscaused by martensitic transformations between a metastablematrix (β phase) and one or more martensitic phases. Inthese alloys, when diffusion becomes significant, precipi...

The effects of post-deposition heat treatment on the microstructure and mechanical properties of boron nitride thin films deposited on 316L stainless steel substrates via radio frequency magnetron sputteringwere investig...

El artículo analiza la evolución y características del empleo y la desocupación en el Gran Tucumán-Tafí Viejo en las distintas fases que componen el período 2003-2015. Para ello, se describe las dinámicas que tuv...

Background: Participatory budgeting (PB) techniques have emerged to promote democratic engagement with local government to influence local government expenditures and ensure priorities of all role-players are incorporat...

Abstract Planetary interiors experience high-pressure-high temperature conditions that give rise to unconventional states of matter, reshaping our understanding of planetary dynamics and the generation of magnetic fields...
