Stereo transmission electron microscopy has been used to characterize the distribution in depth of disordered zones and associated dislocation loops in the ordered alloys Ni3Al and Cu3Au after heavy-ion irradiation, most extensively for Ni3Al irradia

The kinetics of clustering in Al–Mg–Si alloy is studied by means of Kinetic Monte Carlo simulations. The simulations take into account the probability of vacancy jumping to nearest neighbour sites. This probability is calculated by considering bo

The microstructural changes of a Hastelloy alloy under 10 MeV electron irradiation at 650 °C for 700 h to a total fluence of 2 × 10– 3 dpa (displacements per atom) were investigated by transmission electron microscopy and by 3-dimensional atom-pr

The formation of the L12 phase in an A3B intermetallic solid solution has been investigated by Monte Carlo simulation. The ordering is modelled with a simple atomic exchange mechanism based on a fcc Ising model with appropriate values for the pairwis

The interpretation of experiments on the stability of ordered precipitates in irradiation environments demands the detailed knowledge of the 3-d concentration profiles during the dissolution under the irradiation. They can be calculated by a numerica

We discuss the time evolution of local changes in the alloy composition {ital X}({ital r},{ital t}) and in the degree of long-range order {ital S}({ital r},{ital t}) under irradiation with energetic particles. Coupled kinetic equations for {ital X} a

Composition fluctuations arising from thermal effects are known to influence the spinodal decomposition in concentrated alloys. However, at very low temperatures these effects slow down because of the very small diffusionrates. This paper examines th
