Phase Equilibrium Dynamic Model and Thermodynamic Behavior of Tight Gas Hydrate
Shiyou jixie, 2021 Natural gas is easy to form hydrate and continuously accumulate in the process of flowing in wellbore and pipeline. Therefore, this article presents a calculation method of liquid and gas phase fugacity based on Van Laar mixing rule PRSV2 state equation,

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...
