A model is developed that simulates exchange of one hydrogen isotope with another hydrogen isotope in a spherical metal hydride particle. This is one of the fundamental physical processes operative during isotope exchange in a bed of spherical metal

Lattice parameter changes in nanoparticles can be used to determine the surface stress of solids. In the past a Laplace–Young relationship has been employed to interpret the lattice parameter changes as a function of the particle size. In the meant

Recently it was proposed that voids in crystals could grow by emission of shear dislocation loops [V.A. Lubarda, M.S. Scheider, D.H. Kalantar, B.A. Remington, M.A. Meyers, Acta Materialia 52 (2004) 1397–1408]. Even more recently, this proposal was

A novel computational treatment of dense, stiff, coupled reaction rate equations is introduced to study the nucleation, growth, and possible coalescence of cavities during neutron irradiation of metals. Radiation damage is modeled by the creation of

Molecular dynamics simulations of the formation and annealing of large collision cascades in delta-phase plutonium are presented. The defect evolution is followed with time up to 2 ns. Simulations are performed with the MEAM potential at three differ

Ga-stabilized δ-Pu undergoes small changes in density with time. These have been associated with four different causes: an initial reversible expansion that saturates after a short time; a continuous change that can be attributed to the in-growth of

A fast numerical approximation is introduced for the interaction of vacancies and interstitials with a spherical cavity in an isotropic elastic medium. The image interaction is evaluated from a fit which is accurate and simple enough to obtain bias f

Bias factors for dislocations quantify the preferential diffusion of self-interstitials relative to the diffusion of vacancies to dislocations. These parameters are essential for rate theory computer codes that model nucleation and growth of voids, h
