Deuterium/Tritium (D/T) handling in defined proportions are pivotal to maintain steady-state operation for fusion reactors. However, the hydrogen isotope effect metal-hydrogen systems always disturbs precise D/T ratio control. Here, we reveal dominance of kinetic during desorption. To reconcile thermodynamic stability and effect, demonstrate a quantitative indicator T
Thermodynamic relationships among dehydrogenation, hydriding disproportionation and dehydriding reactions in ZrCo–H system.
Ni-Ti-Nb and Ni-Ti shape memory thin films were sputter-deposited onto silicon substrates annealed at 600 °C for crystallization. X-ray diffraction (XRD) measurements indicated that all of the composed crystalline (Nb) Nb-rich grains. photoelectron spectroscopy (XPS) tests showed surfaces covered with Ti oxides, NiO Nb2O5. The corrosion resistance in 3.5 wt.% NaCl solution was investigated using electrochemical such as open-circuit potential (OCP) potentio-dynamic polarization tests. higher...
The shape memory effect and nanoindentation response of various phases sputtered NiTi thin films were investigated as a function temperature. phase transformation temperatures observed to be sensitive compositional shift. mechanical properties also presented significant transformations. At the same load, maximum indentation depth for austenite is smaller than martensite, indicating that martensite softer austenite. A film was converted via in situ heating displayed similar at room These...
This letter demonstrates the effects of structural relaxation on crystallization and phase transformation behavior NiTi thin films. Heat treatments below glass temperature produce films with a greater hardness than as-deposited The reduction in free volume occurring during film plays role. Using scanning electron microscopy, was found to decrease overall time increase nucleation rate, thus modifying resulting microstructures. Structural had little effect temperatures fully crystallized...
We have investigated the optical properties of sputter-deposited silver-aluminum alloy thin films on silicon substrates at room temperature. In addition to primary feature that corresponds bulk plasma resonance, a secondary dip appears in reflectance spectra, which shifts and diminishes with thermal annealing. Careful structural characterization both as-deposited annealed suggests resonant originates from surface plasmon resonances, are localized dielectric gap between grains. This result...
The utilization of titanium aluminide (TiAl) alloys is widespread in the high-temperature sectors aerospace industry, despite their challenging manufacturing process and inherent low toughness. Laser additive (LAM), as a solution to these challenges, enhances capability form complex components mechanical properties. influence parameters, heat treatment methods, reinforcing on microstructure TiAl was studied during LAM process. principles designing were emphasized from action mechanism...
This article presents the investigation results on transformation characteristics of a sputter-deposited Ti–Ni–Cu shape memory alloy thin film and its relation to substrate-induced stress. Experimental show that, with substrate attachment, interval increases while hysteresis decreases in comparison those same free-standing condition. By assuming stress distribution through thickness, layer-by-layer sequence substrate-attached is proposed are analysed. The analysis qualitative agreement...
