在最近的一篇关于钢中贝氏体反应的综述中，其他作者叙述了原共析铁素体、贝氏体和板条马氏体转变的结构和动力学特征，表明它们都是一个单一的、统一的序列的一部分，随着驱动力的增加而演变。在论文的最后，他们邀请对他们的结论进行“建设性的辩论”。通过立即指出我们的基本共识和分歧点，可以有效地介绍对他们的邀请作出的这一反应。关于前者，作者同意Purdy和Hillert以及其他一些同事的观点，即预共析铁素体、上贝氏体和下贝氏体是微观组织发展连续体的一部分，具有重要的共性。他们还一致认为，这些反应的发生速度都不会超过体积扩散控制所允许的速度。然而，在这两个协议领域的基础细节方面，存在着重大的差异。它们不接受下贝氏体和马氏体之间的任何基本连续性。在讨论的最后，对这些问题提出了另一种观点。
In a recent review of the bainite reaction in steel, other authors recounted structural and kinetic features of the proeutectoid ferrite, bainite and lath martensite transformations which suggest that all of them are a part of a single, unified sequence evolving with increasing driving force. At the end of the paper they invited ''constructive debate'' about their conclusions. Introduction of this response to their invitation may be usefully accomplished by noting immediately our basic points of agreement and of disagreement. With respect to the former, the authors agree with Purdy and Hillert, as well as with a number of other colleagues that proeutectoid ferrite, upper bainite and lower bainite are part of a continuum of microstructural development with important commonalities. They also agree that none of these reactions can occur more rapidly than volume diffusion-control allows. However, there is a significant substructure of differences with respect to the details underlying both of these areas of agreement. And they do not accept any fundamental continuity between lower bainite and martensite. At the end of the discussion, another viewpoint on these matters is presented.
