Abstract

The morphology of martensite in widely varying series of Fe-C, Fe-Ni-C and Fe-Cr-C alloys was investigated using optical microscopy. The effects of formation temperature and alloying elements on the martensite morphology were studied in detail. It was found that in Fe-C alloys, lath martensite forms in alloys with less than 0.8wt% carbon, butterfly martensite forms in alloys with between 0.98 and 1.42wt% carbon and lenticular martensite forms in alloys with more than 1.56wt% carbon. In Fe-Ni-C alloys, four different martensite morphologies form depending upon the formation temperature and composition, and for alloys of a fixed carbon content the martensite morphology changes from lath to butterfly to lenticular to thin plate as the formation temperature is decreased. In Fe-Cr-C alloys, lath martensite forms at high temperature, and below the lath formation temperature mainly {2 2 5}_f plate martensite is formed. Based on the results obtained, the importance of the strength of austenite, and the austenite stacking fault energy to the martensite morphology was discussed.

Fe-C、Fe-Ni-C和Fe-Cr-C合金中马氏体的形貌

用光学显微镜研究了不同系列Fe-C、Fe-Ni-C和Fe-Cr-C合金的马氏体形貌。详细研究了形成温度和合金元素对马氏体形貌的影响。结果表明:在Fe-C合金中，碳含量低于0.8wt%的合金形成板条马氏体，碳含量在0.98 ~ 1.42wt%之间的合金形成蝴蝶马氏体，碳含量高于1.56wt%的合金形成透镜状马氏体。在Fe-Ni-C合金中，根据形成温度和成分的不同，可以形成四种不同的马氏体形态，对于固定碳含量的合金，随着形成温度的降低，马氏体形态从板条状到蝴蝶状到透镜状再到薄板状。Fe-Cr-C合金在高温下形成板条马氏体，板条形成温度以下主要形成{2 2 5}板片状马氏体。在此基础上，讨论了奥氏体强度和奥氏体层错能对马氏体形貌的影响。
