摘要
评述了刘宗昌等关于贝氏体铁素体形核的工作,包括:(1)过少有关贝氏体铁素体形核机制文献综述;(2)实验工作远不够形核所要求的精确;(3)母相(奥氏体)中的成分和结构等起伏(涨落)不能成为贝氏体铁素体形核的基础;(4)提出的所谓"贝氏体形成属非切变非扩散机制"未得到先进相变理论和精细实验的支持。
Comment on works concerning the nucleation of bainitic ferrite, authored by Liu Zongchang et al, containing : ( 1 ) few literature concerning nucleation mechanism of bainitic ferrite was cited ; (2) the experiments were far away from the required precision; (3) the composition and structural fluctuations in parent phase (austenite) can not effectively act as the nucleation of bainitic ferrite and (4) the suggested mechanism so called as "non-shear-diffusionless " has not been supported by advanced theory of phase transformation or precise experimental result.
