For a better understanding of multistimuli-responsive caloric materials with first-order transition and for optimization their functional properties, it is necessary to predict the behavior material under changes both magnetic field pressure. Here, we design build special device that can provide self-consistent set parameters needed comprehensive characterization materials. Using this scientific instrument, data simultaneously measured magnetization, ${M(T)}_{H}$, volume magnetostriction,...
The effect of high-pressure torsion (HPT) on the microstructure, phase composition, mechanical characteristics, degradation rate, and bioactive properties Zn-1%Mg alloy is studied. An ultrafine-grained (UFG) structure with an average grain size α-Zn equal to 890 ± 26 nm grains subgrains Mg2Zn11 MgZn2 phases a 50-100 are formed after HPT. This UFG leads increase in ultimate tensile strength by ~3 times elongation 6.3 3.3% due formation basal texture. study corrosion resistance did not show...
The wide application of Nd-Fe-B permanent magnets, in addition to rare-earth metal resource constraints, creates the necessity development efficient technologies for recycling sintered magnets. In present study, a magnet-to-magnet process is considered. As starting materials, magnets different grades were used, which processed by hydrogen decrepitation and blending powder with NdHx. Composition inhomogeneity Nd2Fe14B-based magnetic phase grains recycled existence core-shell structure...
A study of microstructure, phase composition, mechanical properties, corrosion processes, and biocompatibility in vitro the Zn–1%Mg Zn–1%Mg–0.1%Ca alloys an annealed state after rotary swaging (RS) is presented. Partially recrystallized microstructure formed studied RS at 200 °C. reduces mass fraction intermetallic phases comparison with states alloys. °C increases strength up to 248 ± 9 249 growth ductility 10.3 3% 14.2 0.9%, respectively. The structure does not lead a change resistance...
A study of the effect high-pressure torsion (HPT) on structure, phase composition, corrosion resistance, mechanical properties and bioactivity in vitro Zn-1%Mg-0.1%Ca alloy was performed. It shown that HPT leads to refinement microstructure with formation recrystallized α-Zn grains an average size 750 ± 30 nm, a mixture different phases 38 7 nm. In addition, precipitation Ca-enriched particles ~20 nm observed. X-ray analysis showed consists five (Zn, Mg2Zn11, MgZn2, CaZn11 CaZn13), whose...
The structure, phase composition, corrosion and mechanical properties, as well aspects of biocompatibility in vitro vivo, a Zn-1%Mg-0.1%Dy alloy after equal-channel angular pressing (ECAP) were studied. structure refinement ECAP leads to the formation elongated α-Zn grains with width ~10 µm Mg- Dy-containing phases. In addition, X-ray diffraction analysis demonstrated that resulted basal texture alloy. These changes microstructure lead an increase ultimate tensile strength up 262 ± 7 MPa...
In this study, we demonstrate that introduction of rare-earth elements, R = La or Pr, into the Bi–O charge reservoir layer BiCuSeO leads to an increase both carrier concentration and effective mass. Although mobility slightly decreases upon Bi3+ R3+ substitution, electronic transport properties are significantly improved in a broad temperature range from 100 800 K. particular, electrical resistivity by 2 times, while Seebeck coefficient drops 323 238 μV K–1 at Thus, power factor nearly 3 μW...
