【摘要】 本文对板条状马氏体的惯习面和位向关系、板条间相对取向关系的孪晶学说和其 它论点以及板条状马氏体形态模型进行了讨论。根据板条间相对取向的孪晶学说详细 地讨论了可能出现的各类面组合（包括已经被发现者和可能出现者）。作者根据已有 的实验结果认为，一寸马氏体板条束内板条只可能按两组位向转变的结论是很值得商 榷的，随着实验技术的进展必然会逐步揭示一个板条来内板条多取向的可能性。更多还原

【Abstract】 The paper discusses the twin theory and other theses on the habit plane of the lath martensite, the direction relationship and the relative oriented relationship between laths. It also discusses the formation model of the lath martensite According to the twin theory of the relative orientation between laths, the paper deals with such various plane combinations in detail as are possible to arise including those which had been found and those which may arise later. On the basis of the present experiment results, authors consider it necessary to discuss the conclusion that the laths in a beam of martensite lath can only transform in two groups of directions. The possibility of the lath multi-orientation in a lath beam will certainly be brought to light step by step along with tile development of the experiment technique.更多还原
