Abstract:
Al alloys with Mg as the major alloying element constitute a group of non-heat treatable alloys with medium strength, high ductility, excellent corrosion resistance and weldability. However, the segregation of Mg may adversely affect the performance of these materials if they are exposed to rapid heating and cooling environments such as resistance spot welding. The formation and migration of vacancy is an important factor affecting Mg segregation. In this paper, the amount and distribution of Mg were measured by electron probe microanalysis and the vacancy formation energy in AA5754 alloys was

Abstract:
The effect of chromia additive on defects in yttria stabilized zirconia (YSZ) nanopowders was investigated in this work. It was found that positrons are trapped at vacancy-like misfit defect at grain boundaries and at larger defects situated at triple points. Moreover, a long-lived ortho-positronium contribution was found in YSZ nanopowder without chromia. Addition of chromia prolongs the lifetime of positrons trapped at vacancy-like misfit defects which indicates segregation of Cr ions at grain interfaces and interaction of Cr with vacancy-like misfit defets. Moreover addition of chromia comp

Abstract:
Tritium interactions with irradiation-induced defects in α-Zr are important for understanding getter performance in tritium-producing burnable absorbed rods. Vacancy-type basal loops are prominent in α-Zr irradiated at high dose rates. As they generate substantial tensile strain fields, such loops can trap tritium atoms. For this reason, vacancy-type basal dislocation loops are potentially important for tritium transport, tritium solubility, and tritide precipitation. We perform molecular dynamics simulations of tritium distributions around vacancy-type basal dislocation loops of different siz

Abstract:
In this paper, the diffusion coefficient of vacancy-solute complex and diffusion coefficient of solute atoms, P, in non-equilibrium grain-boundary segregation under low tensile stress in steel 12Cr1MoV are calculated based on the model developed by Xu. Both the simulation and experimental kinetics curves are achieved. Results show that the calculated result with the kinetic equations perfectly fits with the experimental observations for phosphorus in steel 12Cr1MoV under low tensile stress. In the segregation process, the rate of phosphorus segregation is high due to a large diffusivity of the

Abstract:
The atomic structure of antiphase boundaries in Sr-doped lanthanum scandate (La1−xSrxScO3−δ) perovskite, promising as the proton conductor, was modelled by means of DFT method. Two structural types of interfaces formed by structural octahedral coupling were constructed: edge- and face-shared. The energetic stability of these two interfaces was investigated. The mechanisms of oxygen vacancy formation and migration in both types of interfaces were modelled. It was shown that both interfaces are structurally stable and facilitate oxygen ionic migration.

Abstract:
We computed the atomic shift sizes of the closest adjacent atoms adjoining the (001) surface F-center at ABO3 perovskites. They are significantly larger than the atomic shift sizes of the closest adjacent atoms adjoining the bulk F-center. In the ABO3 perovskite matrixes, the electron charge is significantly stronger confined in the interior of the bulk oxygen vacancy than in the interior of the (001) surface oxygen vacancy. The formation energy of the oxygen vacancy on the (001) surface is smaller than in the bulk. This microscopic energy distinction stimulates the oxygen vacancy segregation

Abstract:
Grain boundaries (GBs) influence many physical and mechanical properties of crystalline materials. This is primarily because of their interactions with other kinds of defects, such as point and line defects. Such interactions are known to depend on the structure and properties of individual GBs, i.e. the GB character. Although much research has been done in this regard, an understanding of the effect of GB character on such interactions is still incomplete. The present study was undertaken to particularly understand the effect of GB character on vacancy--GB interactions in aluminium (Al). T

This chapter examines how different rationalities and practices of governing vacant housing have formed in the context of intersecting local, regional and national policies and projects in Halle/Saale. It draws attention to the conflicting rationalities and messy actualities of devaluing certain types of housing while reclaiming and promoting others.

Abstract:
Abstract Grain boundary Cr concentration influences resistance to intergranular stress corrosion cracking of stainless steel reactor core components. Therefore it is important to understand (1) how initial thermal processing affects thermal nonequilibrium segregation (TNES), (2) how service exposure affects radiation-induced segregation (RIS), and (3) how temperature affects post-irradiation annealing (PIA). In this study, each process is shown to be controlled by Cr-vacancy interactions. Mechanistic predictions are in accord with measured kinetics of changes in grain boundary Cr concentration

Abstract:
Abstract High gate to source/drain (S/D) leakage was observed at both failed pins and ET structures with random failure signatures. Detailed TEM failure analysis revealed an abnormal thin Nitrogen-rich nitride layer along the poly gate which extended to the S/D regions. Along the abnormal nitride layer, appreciable Arsenic (As) segregation occurred. The segregated As dopants at these interfaces may form a continuous conducting path, accounting for the gate to S/D leakage mechanism. The preferable As segregation at the Silicon nitride interface may be related to a vacancy-assisted As diffusion
