Stochastic Computer Simulation of High-temperature Blistering at Fluctuation Stage into Multylayer Medium
Abstract:
Stochastic computer simulation of vacancies-gaseous defects into crystal lattice is applied to investigation of alternating thin layers medium of technological metal mirror. These diagnostic devices are used for radiation focuses on the detectors. The vacancies-gaseous defects storage into lattice (or blistering) is caused by fluxes of high energy particles which migrate beneath the surface. Radiation stimulated defects and its clusters (or bubbles with alternating mass) participate in Brownian motion which leads to follows: porosity, stress of lattice as well as to roughness with peaks and craters on the surface and flaking off of surface layer. Kinetic model of the first order phase transition in form of blistering worked out and it may be used in technologies materials and structures producing.
