Hierarchical Ordering Induced Ultrahigh Cryogenic Strength and Strain Hardening in a Ni2CoFeV Medium‐Entropy Alloy

Advanced Science, EarlyView.
A tri‐phase Ni2CoFeV medium‐entropy alloy with fcc, κ, and L12 phases achieves exceptional cryogenic strength‐ductility synergy at 77 K. It delivers a yield strength of 1.4 GPa, an ultimate tensile strength of 2.07 GPa and a tensile ductility of 28%.

A General Criterion for Liquefaction in Granular Layers with Heterogeneous Pore Pressure [PDF]

, 2013
International audienceFluid-saturated granular and porous layers can undergo liquefaction and lose their shear resistance when subjected to shear forcing. In geosystems, such a process can lead to severe natural hazards of soil liquefaction, accelerating

Resolving passive heat transfer and phase‐change heat in cryogenic CO2 deposition (Desublimation) from CO2/N2 mixtures

AIChE Journal, EarlyView.
Abstract In cryogenic CO2 desublimation systems where phase change dominates both heat transfer and separation, conventional lumped thermal‐resistance treatments embed interfacial latent heat into an overall heat‐transfer coefficient, obscuring how phase‐change heat is partitioned between the gas phase and the coolant and limiting diagnostic insight ...

Effect of cement content on the static and dynamic liquefaction resistance of fine tailing

Case Studies in Construction Materials
Cement tailings storage (CTS) in goaf may experience static and dynamic loading, such as rock stress, mine earthquake and blasting stress. When subject to dynamic loading, the risk for liquefaction of CTS may cause goaf barricade instability.

Pore Water Pressure Generation and Energy Dissipation Characteristics of Sand–Gravel Mixtures Subjected to Cyclic Loading

Geotechnics
At least 32 case histories have shown that liquefaction can occur in gravelly soils (both natural deposits and manmade reclamations) during severe earthquakes, causing large ground deformations and severe damage to civil infrastructures.
