The physical-mechanical properties of Ti-Ni-Ta and Ti-Ni-Ta-Si-based surface alloys ~1 μm thickness synthesized on the NiTi substrates by additive thin-film electron beam method were investigated. effect these functional composite systems [Ti-Ni-Ta alloy/TiNi substrate] [Ti-Ni-Ta-Si was explored. It established that Ti-Ni-Ta-Si based alloy with an amorphous structure is characterized higher gra...

This paper presents a variational multiscale method for developing stabilized finite element formulations for small strain inelasticity. The multiscale method arises from a decomposition of the displacement field into coarse (resolved) and fine (unresolved) scales. The resulting finite element formulation allows arbitrary combinations of interpolation functions for the displacement and the pres...

Superelastic graphene aerogel with ultra-high compressibility shows promising potential for compression-tolerant supercapacitor electrode. However, its specific capacitance is too low to meet the practical application. Herein, we deposited polyaniline (PANI) into the superelastic graphene aerogel to improve the capacitance while maintaining the superelasticity. Graphene/PANI aerogel with optimi...

In this work, a (TiHfZr)(NbTa)26 (%at) high-entropy quinary alloy has been developed especially for high-temperature superelastic applications and studied over large range of temperatures. The mechanical properties new material were compared with those other alloys. different ingots have made in cold crucible from pure metals. Several thermomechanical treatments performed on the microstructure ...

The regularities of the change in inelastic strain coarse-grained samples Ti49.3Ni50.7 (at%) alloy are studied when given torsional state high-temperature B2 phase. During cooling and heating, investigated underwent B2–B19′ martensite transformation (MT); temperature end reverse MT was Af = 273 K. It found that at isothermal cycles “loading-unloading” + 8 K, specimen is assigned a 4%, effect su...
