Hydrogen localization under thermal gradients in hydride forming metals
K. A. Forsberg, A. R. Massih
Migration of hydrogen and hydride formation under thermal gradient leads to hydrogen redistribution in certain metals. These metals include zirconium, titanium, hafnium and their a…
Hydrogen redistribution in Zr-base cladding under gradients in temperature and stress
Lars O. Jernkvist, Ali R. Massih
Computational models are used here for simulating diffusion-controlled redistribution of hydrogen that is picked up by zirconium-base nuclear fuel cladding during light water react…
Solid state phase transformation kinetics in Zr-base alloys
A. R. Massih, L. O. Jernkvist
We present a kinetic model for solid state phase transformation (alpha<-->beta) of common zirconium alloys used as fuel cladding material in light water reactors. The model compute…
Nucleation of second-phase near elastic defects in crystalline solids
Christina Bjerkén, Ali R. Massih
The problem of heterogeneous nucleation of second-phase in alloys in the vicinity of elastic defects is considered. The defect can be a dislocation line or a crack tip residing in…
Stress orientation of second-phase in alloys: Hydrides in zirconium alloys
Ali R. Massih, Lars O. Jernkvist
A model for precipitation of the plate-shaped second-phase under applied stress is presented. The precipitates in the matrix-precipitate system are represented by their local volum…
Diffusion of particles in an expanding sphere with an absorbing boundary
Karl Forsberg, Ali R. Massih
We study the problem of particles undergoing Brownian motion in an expanding sphere whose surface is an absorbing boundary for the particles. The problem is akin to that of the dif…
