In order to explore the graphitization of inertinite, this paper conducted high-temperature thermal simulation experiments (HTT) and high-pressure (HTHP) on isolated samples enriched in inertinite. X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM) were used analyze process ① Results HTT: inertinite has a “threshold condition” with temperature threshold ranging ...

Graphitization in carbon steels must be prevented because it reduces the amount of matrix, which degrades material performance due to loss strength. In addition, when graphite particles are aligned, they can cause fracture by their linkage. The safety management standards for high-temperature applications state that graphitization should considered at 698 K and above. number reported cases on b...
