为了快速准确检测出GCr15碳化物带状,并进行评级。本文对GCr15带状碳化物的形成过程进行了阐释,找出了检验过程中的重点部位;并通过试验对球化退火处理和未经球化退火后的试样进行比较,结果表明经球化退火试样要比未经球化退火试样带状评级要高约0.5级,从而提出可在未球化退火试样上对GCr15带状碳化物进行评级,简化了GCr15检验前的热处理工艺,提高了工作效率,降低了热处理加工成本。 GCr15 carbide bands were quickly and accurately detected and rated. In this paper, the forming process of GCr15 banded carbides was explained, and the key parts in the testing process were found out. The ball annealing and non-ballizing annealed samples were compared by the test. The annealed sample is about 0.5 higher than that of the non-spheroidized annealed sample. Therefore, it is proposed that the GCr15 banded carbide can be rated on the non-pelletized annealed sample to simplify the heat treatment process before the GCr15 test, Improve work efficiency, reduce the heat treatment processing costs.
