The paper considers kinetics of short-range ordering of hydrogen atoms in ternary iron-base alloys containing a substitutional
impurity strongly interacting with hydrogen (Pd) under fast supercooling. Kinetics of change of order parameter and hydrogen solubility is calculated both for isothermal holding and continuous cooling.
Key words: iron alloys, hydrogen, Fe–Pd–H alloys, short-range order, kinetics.
