Interaction mechanisms between C15 Laves phase clusters and 〈1 1 1〉 dislocation loops in BCC-Fe: An atomistic perspective

Results in Physics
Small C15 Laves phase clusters are extended interstitial defects that form during collision cascades in body-centered cubic (BCC) iron. Although their stability has been confirmed by ab initio calculations up to a certain size, their interactions with ...

Dislocation Loops with a Burgers Vector Produced by 1 MeV Electron Irradiation in FCC Copper-Nickel

, 1975
Dislocation loops with Burgers vector a are formed in Cu-Ni alloys during 1 MeV electron irradiation in a high-voltage electron microscope at 350°-400°C. The dislocation loops are of interstitial type and pure edge in character with line vectors. Some of

Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Damage behavior of additive manufacturing 316L stainless steel irradiated with Fe ions

Nuclear Materials and Energy
The irradiation damage behavior of 316L stainless steel (SS) fabricated using selective laser melting (SLM) and traditional manufacturing (TM) was investigated in terms of microstructural changes in hardness and swelling at RT under irradiation with 3 ...

Irradiation tolerance of Co-free high entropy alloy: a quantitative microstructural evaluation of the effect of irradiation damage dose

Materials & Design
High entropy alloys (HEAs) are potential structural materials for next-generation nuclear systems due to their excellent high-temperature strength and corrosion resistance. However, their viability in extreme environments remains uncertain, necessitating

Collapse of Defect Cascades to Dislocation Loops in Cu3Au [PDF]

, 1986
TEM and ordered Cu/sub 3/Au were employed to measure the probability of dislocation loop formation as functions of irradiating ion mass (Ar/sup +/, Cu/sup +/ and Kr/sup +/), energy (50 and 100 keV), and irradiation temperature (30 and 300/sup 0/K ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
