共析分解是合金中扩散型固态相变之一。二元合金中的高温固相,在一定的温度下,分解为在该温度稳定的两个新合金相,一个贫第二组元,另一则富第二组元。新合金相可以是两个固溶体(或纯组元),也可以是一个固溶体(或纯组元)和一个化合物或两个化合物。
共析分解是个自组织过程,具有铁素体和渗碳体互为领先相的整合机制。
The eutectoid decomposition is a self organization process, which is characterized by the integrated mechanism that ferrite and cementite acted as prevenient phase alternatively.
研究贝氏体相变的特点,弄清贝氏体相变反应与共析分解的区别极为重要。
It is important to understand the difference of bainite transformation and eutectoid decomposition in steels.
提高退火温度,尤其是在高于共析温度退火有助于加快块状组织的分解过程。
With the increase of annealing temperature, the decomposition process of massive microstructure will be accelerated.
