Radiation-induced Segregation in Ni Alloys by Deuterium Ion Irradiations

(100) surface segregation in Cu-Ni alloys.

Phase transformations and segregation in Fe–Ni alloys and nanoalloys

Ordering and segregation properties of Fe–Ni alloys and nanoalloys are investigated by means of Metropolis Monte Carlo (MMC) and molecular dynamics (MD) simulations. The model is based on an embedded atom potential which, according to thermodynamic integration, only stabilizes those phases that are observed experimentally. This stability is confirmed by MMC and the same phases are found stable ...

Radiation Produced by Glow Discharge in Deuterium

Radiation produced by low-voltage discharge in a gas containing deuterium was measured using a Geiger counter located within the apparatus. This radiation was found to consist of energetic particles that were produced only when the voltage was above a critical value. In addition, the emission was very sensitive to the presence of oxygen in the gas. In the presence of the required conditions, em...

Microstructural Examination of Ni-ion Irradiated Fe-Ni-Cr Alloys Followed to Micro-zone Deformation

Examination of deformation microstructures induced by micro-indentation technique by means of transmission electron microscopy following an MV range metallic ion irradiation was performed in order to study the influence of irradiation-produced microstructural defects on plastic deformation behavior of materials. In this work, specimens of an Fe-Cr-Ni austenitic model ternary alloy before and af...
