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。
In 1966, Aaronson disagreed on the theory of shear in bainite transformation of steel based on thermodynamic calculations, leading to a worldwide study and discussion of the bainite transformation mechanism of steel for more than half a century Some issues have been agreed upon, but some issues remain divided. During this period, there have also been some new contributions to the transformation of martensite and pearlite. Now with special iron and carbon steel, for example, pearlite, bainite, martensite transformation mechanism of the current status are summarized, including some of the authors of this analysis and judgment. Sincerely hope that readers will criticize this article.
