Residual stress relief mechanisms of 2219 Al–Cu alloy by thermal stress relief method
Reviews on Advanced Materials Science, 2022 Monolithic thin-wall components of 2219 Al–Cu alloy are widely used in aerospace and military fields, and usually treated with solution and quenching to improve their comprehensive performance. However, a high magnitude residual stress is introduced into

Crystals, 2017 Continuous diamond films with low dislocation density were obtained by two-step epitaxial lateral overgrowth (ELO). Grooves were fabricated by inductively coupled plasma etching. Mo/Pd stripes sputtered in the grooves were used to inhibit the propagation

Faceting and Twin–Twin Interactions in {1121} and {1122} Twins in Titanium
Metals, 2022 Twin–twin interactions are an important component of the microstructural evolution of hexagonal close-packed metals undergoing plasticity. These interactions are prevalent because of the predominance of twinning due to limited easy slip modes.

Unveiling the Mechanisms of High-Temperature 1/2[111] Screw Dislocation Glide in Iron–Carbon Alloys
Crystals, 2022 We have developed a self-consistent model for predicting the velocity of 1/2[111] screw dislocation in binary iron–carbon alloys gliding by a high-temperature Peierls mechanism.

Vacancy-induced dislocations within grains for high-performance PbSe thermoelectrics
Nature Communications, 2017 To minimize the lattice thermal conductivity in thermoelectrics, strategies typically focus on the scattering of low-frequency phonons by interfaces and high-frequency phonons by point defects.

Deslocamentos em dois cortejos processionais católicos
Religião e Sociedade, 2008 As observações sobre duas procissões em honra de S. Sebastião, Padroeiro católico do Rio de Janeiro, oferecem a possibilidade de análises com respeito a um conjunto de deslocamentos os quais refletem atos ou situações de transitividade observados hoje em

Multiscale modeling of dislocation-precipitate interactions in Fe: From molecular dynamics to discrete dislocations. [PDF]
Physical Review E, 2016 The stress-driven motion of dislocations in crystalline solids, and thus the ensuing plastic deformation process, is greatly influenced by the presence or absence of various pointlike defects such as precipitates or solute atoms.

Strength and plasticity of nanolaminated materials
Materials Research Letters, 2017 The mechanical behavior of nanolaminates is dominated by interfaces that act as sources, barriers, and preferred sites for storage and dynamic recovery of glide dislocations.

60 years of dislocations in ceramics: A conceptual framework for dislocation mechanics in ceramics
International Journal of Ceramic Engineering & Science, 2022 High‐tech ceramics are typically engineered by controlling point defects and interfaces while one‐dimensional dislocations have found much less attention so far.
