简要总结了钢中珠光体相变的机制，特别是珠光体形核的晶体学和长大的动力学。
The mechanisms for the formation of pearlite in steels are reviewed in brief with particular reference to the role of crystallography in nucleation and the kinetics of growth.
相变后的最终组织为大量铁素体加部分珠光体。
The microstructure after phase transformation consists of ferrite mainly and some pearlites.
以相变动力学为基础，研究了奥氏体向铁素体、珠光体和贝氏体转变的温度和相变体积分数的计算方法。
On the basis of transformation kinetics, the transformation of austenite to ferrite, austenite to pearlite, austenite to bainite was investigated.
而铌元素的加入增大了过冷奥氏体的稳定性，相变点温度降低，并且推迟珠光体的转变。
But Nb adding increases the under-heating austenite stability, reduces the temperature of phase transformation point and postpones the transformation of pearlite.
