Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

Advanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Deformation Behavior of Diaphragm Walls and Ground Surface During Excavation of a Circular Deep Foundation Pit Considering Coupled Dewatering and Recharge Effects

Buildings
Few studies have focused on the deformation of ultra-deep circular foundation pits under the combined effects of dewatering and recharge. Therefore, a case of an ultra-deep circular foundation pit in a soft soil area was selected to investigate the ...

Model-Agnostic Meta-Learning in Predicting Tunneling-Induced Surface Ground Deformation

Symmetry
The present investigation presents the field measurement and prediction of tunneling-induced surface ground settlement in Tianjin Metro Line 7, China. The cross-section of a metro tunnel exhibits circular symmetry, thereby making it suitable for tunneling with a circular shield machine. The ground surface may deform during the tunneling stage.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Evaluating the Effects of Deep Excavation on Nearby Structures Through Numerical Simulation

Applied Sciences
Traditional numerical analyses often overlook the potential impact of adjacent building basements on ground surface deformation. This study investigated the influence of neighboring structures on diaphragm walls and ground surface deformation during deep

Notes on the Vertical Deformations of the Ground Surface in the Central Part of the City of Tokyo.

Journal of Physics of the Earth, 1952
1. The vertical displacements of the ground surface in the central part of the city of Tokyo, which have been detected by levelling surveys repeated recently, consist of two components, namely, the sinking due to the shrinkage of the soft superficial soil layer and the displacement resulting from tilt of the underlying layer of harder material.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

Advanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Spatiotemporal Displacement and Frozen-Ground Conditions of the Baishuigou Rock Glacier Revealed by InSAR and In Situ Observations

Remote Sensing
Rock glaciers are important geomorphic indicators of mountain permafrost conditions, yet the mechanisms controlling spatially heterogeneous deformation within individual rock glaciers remain poorly understood.

On the monitoring of surface displacement in connection with volcano reactivation in Tenerife, Canary Islands, using space techniques [PDF]

, 2002
Geodetic volcano monitoring in Tenerife has mainly focused on the Las Cañadas Caldera, where a geodetic micronetwork and a levelling profile are located.

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...
