摘要

采用光学显微镜研究了以离心铸管形式生产的45Ni-35Cr-Nb合金(俗称ET45微合金)在1073和1173 K下经过不同时间时效处理后的形貌。描述了M23C6次生碳化物析出现象随时间的变化规律。采用JMAK (Johnson-Mehl-Avrami-Kolmogorov)模型分析表明，二次碳化物的析出是单阶段的。结果表明，在扩散的辅助下，该现象的活化能为196 kJ/mol。

STUDY OF M23C6 PRECIPITATION IN A 45Ni-35Cr-Nb ALLOY

The 45Ni-35Cr-Nb alloy, commonly known as ET45 micro, produced in the form of centrifugally cast tubes, was studied by means of optical microscopy after aging treatments at 1073 and 1173 K for different times. A description of M23C6 secondary carbides precipitation phenomenon was made as a function of time. The analysis after using the Johnson–Mehl–Avrami–Kolmogorov (JMAK) model showed that the secondary carbide precipitation occurs in a single stage. It was found that this phenomenon, which is assisted by diffusion, has an activation energy of 196 kJ/mol.
