Phenomenology and nature of changes in the grain structure of the magnesium alloy МА14 hot-pressed rod under multi-step isothermal forging to total strain of 10,2 in the temperature range of 200-400 0С were analyzed. It is shown, that continuous recrys-tallization is the main mechanism of transformations of the initial partially recrystallized structure into homogeneous fine-grained one with ~4 m grain size.
