共析转变;
Both the austenite-graphite eutectic reaction temperature and eutectoid reaction temperature are higher than those of austenite-cementite.
奥氏体-石墨共晶和共析反应温度也都高于奥氏体-渗碳体的共晶和共析反应温度。
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.
由形核(长大)驱动力的计算证明,亚共析钢共析反应的领先相为铁素体,而过共析钢的领先相为渗碳体。
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。
