Solid state phase transformation kinetics in Zr-base alloys
Abstract We present a kinetic model for solid state phase transformation ( $$\alpha \rightleftharpoons \beta$$ α ⇌ β ) of common zirconium alloys used as fuel cladding material in light water reactors. The model computes the relative amounts of $$\beta$$ β or $$\alpha$$ α phase fraction as a functio...
