Ultra fine grain formation during hot rolling process is a systematic change.
在热轧过程中,超细颗粒形成是一个系统性的变化过程。
It is not a simple physical procedure.
它不是一个简单的物理过程.
The process includes deformation and
under-cooling of austenite,
这个过程包含变形和冷却,
dynamic recrystallization and also includes recovery,static,
动态的重新结晶,还包括恢复,静态的
continuous and un-continuous phenomena depending deformation and
temperature conditions,
在变形和静态的条件下所导致的连续的或者不连续的现象,
and the phase transformation procedure.
和这个渐变阶段
See Figure 1.19.
参照图1.19
The first chapter of this book describes only austenite conditioning at high
temperatures that is the preparation stage for the following procedures.
这本书的第一章介绍了奥氏体温度在高温度的条件下 下列程序的准备过程.
热轧过程中超细颗粒的形成过程是一个系统性的变化。它不是一个简单的物理过程。该过程包括：形变，过冷奥氏体，动态再结晶也包括基于形变和温度限制的恢复，静止，连续和非连续的现象，及相变过程。参见图1.19。这本书的第一章仅介绍了奥氏体仅在高温下的调节工程，即如下过程的准备阶段。
热轧过程中超细晶粒的形成是一个系统的变化，而非简单的物理过程。这个过程包括变形和奥氏体的过冷，动态再结晶，还包括不同变形和温度条件下的恢复，静态的，持续的和非持续的现象，以及相位变化过程，参见图1.19。本书第一章仅描述在高温条件下的奥氏体，这是后续各个步骤的准备阶段。
