Abstract
Using a mathematical model of nonequilibrium crystallization of polymorphous metals with a narrow range of stability of the high-temperature modification, we have conducted numerical analysis of the kinetics of the formation of the metastable polytype of cerium (μ-Ce) that is fixed by melt quenching at cooling rates more than ∼105 K/s. Agreement between the calculation data and the results of X-ray diffraction phase analysis of rapidly quenched foils has been obtained at a physically reasonable value of the model parameter having the meaning of the degree of metastability of μ-Ce.
