Calculation of the driving force for nucleaction ( growth) gives an evidencs that the leading phase of the eutectoid reaction in hypoeutectoid steels is ferrite while that in hypereutectoid steels is cementite.

When cooling, peritectic reaction between α-Mg and Zr happened in the Zn-rich area in the grains, while eutectic reaction and eutectoid reaction happened in grain boundaries.

冷却时，α-Mg与Zr在晶内富Zn处发生包晶反应，晶界处发生共晶反应和共析反应。
