Notes on the two-phase model for radiation-induced dimensional changes in graphite☆

摘要: Abstract The historical development and modifications to the “single-phase model” of graphite structure, used interpret predict behavior during neutron irradiation, are outlined. In singlephase model all parts artificial aggregate assumed behave as if they were part a crystal lattice. It is shown that changes occurring in non-graphitic carbon phase, relief internal stresses induced cool-down from graphitization temperature, chances crack structure must also be considered interpretation dimensional produced high-temperature irradiations.
