Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Evolution of crystallographic texture and material anisotropy effects resulting from uniaxial deformation for high‐strength steels with high manganese content

Journal of Applied Crystallography, EarlyView.
The present study investigates the deformation behavior of high‐strength steels and the associated evolution of material anisotropy. Particular focus is placed on the impact of crystallographic texture and intergranular strains on how residual stresses can be evaluated using X‐ray diffraction and the associated assessment of weld seams in the ...

Constraints from rocks in the Taiwan orogen on crustal stress levels and rheology [PDF]

, 2012
Taiwan's Hsüehshan range experienced penetrative coaxial deformation within and near the brittle-plastic transition between ∼6.5 and 3 Ma. This recent and short-lasting deformation in an active, well-studied orogen makes it an ideal natural laboratory ...

Describing neutron spin echo data from undulating lipid vesicles: recent advances

Journal of Applied Crystallography, EarlyView.
We present results and practical considerations for the analysis of neutron spin echo data from vesicles with undulating membranes using a framework that was recently published [Granek et al. (2024). Eur. Phys. J. E47, 12]. We show the importance of vesicle diffusion, size, lamellarity and osmotic pressure as well as the effects of membrane viscosity ...

Influence of strain history on the mechanical and micro-fabric evolution of calcite rocks: insights from torsion experiments [PDF]

, 2018
Different types of deformation experiments were conducted on specimens of Carrara marble at a temperature of 1000 K, 300MPa confining pressure, and 3 × 10−4s−1 shear strain rate.

Scale-dependent influence of pre-existing basement shear zones on rift faulting : a case study from NE Brazil [PDF]

, 2013
Rifting of continental crust initiates faults that are commonly influenced by pre-existing structures. We document newly identified faults cutting Precambrian units in the interior of the NE Brazilian margin to assess the effects of structural ...

The complex stacking disorder of Fe‐ and Ru‐based 1,1′‐(3,6‐pyrazabolyl)metallocenes

Acta Crystallographica Section B, EarlyView.
The ferrocene Fc(BHpz)2 and the ruthenocene Rc(BHpz)2 belong to the same order–disorder (OD) polytype family and feature a complex stacking disorder, with different ordered and disordered domains in the same crystal.1,1′‐(3,6‐Pyrazabolyl)ferrocene [Fc(BHpz)2] and the corresponding ruthenocene [Rc(BHpz)2] crystallize as order–disorder (OD) structures ...

Eocene and Miocene extension, meteoric fluid infiltration, and core complex formation in the Great Basin (Raft River Mountains, Utah) [PDF]

, 2015
Metamorphic core complexes (MCCs) in the North American Cordillera reflect the effects of lithospheric extension and contribute to crustal adjustments both during and after a protracted subduction history along the Pacific plate margin. While the Miocene-
