介绍了测定氧化鳞片生长应力的实验技术，并对实验结果进行了简要总结。由不同的工作者提出的理论来解释生长压力的存在是批判性的审查。讨论了氧化过程中塑性流动发生的原因，并简要描述了氧化物蠕变的各种机制；强调外在过程的明显重要性。详细介绍了化学计量学对氧化物塑性的影响，并讨论了化学计量学对可移动晶格缺陷的影响。研究了金属基体中空位注入和位错产生的问题。最后，对进一步的实验研究提出了一些建议。
The experimental techniques for determining the growth stresses in oxide scales are described, and the results briefly summarized. The theories proposed by various workers to account for the existence of growth stresses are critically reviewed.The reasons for suggesting that plastic flow takes place during the oxidation process are discussed, and the various mechanisms proposed for creep in oxides are briefly described; the apparent importance of extrinsic processes is emphasized. A detailed survey of the effect of stoichiometry on oxide plasticity is given, and the implications of this in terms of mobile lattice defects is discussed. The problems of vacancy injection and dislocation generation in the metal substrate are also examined.Finally, a number of suggestions are made for further experimental investigations.
