We have experimentally determined the main thermodynamic properties of SrCl2, a potentially promising salt for thermochemical heat storage. found high energy density 2.4 ± 0.1 GJ/m3 and proved full cyclability at least 10 cycles going from anhydrate to hexahydrate without chemical degradation. equilibria each individual transition corresponding metastable zones. find that zone is widest monohyd...

Metastable phase equilibria in the W-C system are presented in the vicinity of the metastable reactions involving W2C, WC1-x, and WC. Metastable phase boundaries were obtained by reproducing the stable boundaries using optimized Gibbs energy formulations and extrapolating them into regions of metastability. Four metastable reactions were obtained: a metastable congruent melting reaction of WC a...

Experimental measurements of colloidal crystallization in a wide range of volume fractions of charged particles were performed to investigate the liquid-metastable-stable transition process. To fit the obtained experimental data, we developed a theoretical model to formulate the kinetics of the concurrent liquid-metastable and metastable-stable transitions. This model is well-supported by our o...

The medium Mn steels are gaining increasing attention due to their excellent combination of mechanical properties and material cost. A cold-rolled 0.1C5Mn medium Mn steel with a ferrite matrix plus metastable austenite duplex microstructure was resistance spot-welded with various welding currents and times. The nugget size rose with the increase of heat input, but when the welding current excee...

This paper presents an efficient filtering system for a metastable state-based true random number generator. To output a result with high randomness, we use loop-storage for storing the value of metastability. During the metastable state, the output value is accumulated to the storage. When the non-metastable state arises, the stored metastable value will be used for output instead of the resul...

We report on high-pressure torsion (HPT) processing of Si and related semiconducting materials, discuss their phase transformations electrical, thermal, optical properties. In-situ synchrotron x-ray diffraction revealed that the metastable bc8-structure Si-III r8-structure Si-XII in HPT-processed samples gradually disappeared hexagonal-diamond Si-IV appeared during annealing up to 473 K. The fo...

A thin low-velocity layer that continues from the surface down to at least 135 km depth has been detected within the subducted slab through the analysis of a three-component short-period set of digital data from seismic stations in southern Taiwan. Two distinct phases in the first few seconds of the P-waves generated by nine intermediate-depth earthquakes are observed at one station (TAW) locat...

We show how coupling techniques can be used in some metastable systems to prove that mean metastable exit times are almost constant as functions of the starting microscopic configuration within a “metastable set”. In the example of the Random Field Curie Weiss model, we show that these ideas can also be used to prove asymptotic exponentiality of normalized metastable escape times.
