【摘要】：1966年Aaronson根据热力学计算结果对钢的贝氏体转变的切变理论提出了异议,由此引发了一场世界范围的超过半个多世纪的对钢的贝氏体转变机制的研究和讨论高潮,有些问题已经得到共识,但有些问题依然存在分歧。在此期间,对马氏体转变及珠光体转变也有一些新的建树。现特以纯铁及碳钢为例,对珠光体、贝氏体、马氏体3个转变机制的现状进行了概括,其中包括了本文作者的一些分析和判断。衷心希望读者对本文提出批评指正。
[Abstract]:In 1966, Aaronson challenged the shear theory of bainite transformation on the basis of thermodynamic results, which led to a worldwide high tide of research and discussion on the bainite transformation mechanism of steel for more than half a century. Some issues have been agreed upon, but some remain divided. During this period, there are some new achievements in martensite transformation and pearlite transformation. In this paper, taking pure iron and carbon steel as examples, the present situation of three transformation mechanisms of pearlite, bainite and martensite is summarized, including some analysis and judgement made by the author of this paper. I sincerely hope that the reader will criticize this article.
