On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

PT-conditions of deformation within the Palaeoproterozoic South Finland shear zone: Some geothermobarometric results [PDF]

Bulletin of the Geological Society of Finland, 2005
Four rock samples were collected from the crustal-scale South Finland shear zone in order to compare PT-conditions of deformation between gneissose and mylonitic rock types.

Microstructure and geochronology of pseudotachylite from the Hamm Peak, East Antarctica, and its geological significances

Dizhi lixue xuebao, 2021
The pseudotachylite in granulite facies granitic gneisses from the Hamm Peak, southwestern Prydz Bay, East Antarctica, occurs along the east-west-trending ductile-brittle shear zone. The characteristics of microstructure show that the pseudotachylite was

Kinematics and Vorticity in Kangmar Dome, Southern Tibet: Testing Midcrustal Channel-flow Models for the Himalaya [PDF]

, 2010
Kinematic, kinematic vorticity (Wm), and deformation temperature analyses were completed to test the hypothesis that midcrustal rocks exposed in the core of the Kangmar gneiss dome, southern Tibet record ductile deformation patterns of a “frozen” segment

EBSD Study of Creep‐Induced Lattice Misorientation in MgO‐Particle‐Reinforced Austenitic Steel Composites

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.

Structural deformation and geochronology of the ductile shear zone along the southern margin of the Foping dome, South Qinling

Dizhi lixue xuebao
Objective  A typical granulite–migmatite–gneiss dome developed in the Foping area of the central Qinling orogenic belt. This area is key to studying the metamorphic deformation of continental crust and the Mesozoic tectonic evolution of Qinling.

Effect of Weld Current on the Microstructure and Mechanical Properties of a Resistance Spot-Welded TWIP Steel Sheet

Metals, 2017
In this study the effect of the weld current on the microstructure and mechanical properties of a resistance spot-welded twinning-induced plasticity (TWIP) steel sheet was investigated using optical microscopy, scanning electron microscopy–electron back ...

A new perspective on the significance of the Ranotsara shear zone in Madagascar [PDF]

, 2018
The Ranotsara shear zone in Madagascar has been considered in previous studies to be a >350-km-long, intracrustal strike-slip shear zone of Precambrian/Cambrian age.

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Fault textures in volcanic conduits: evidence for seismic trigger mechanisms during silicic eruptions. [PDF]

, 2005
It is proposed that fault textures in two dissected rhyolitic conduits in Iceland preserve evidence for shallow seismogenic faulting within rising magma during the emplacement of highly viscous lava flows. Detailed field and petrographic analysis of such
