| Abstract: | The microstructural features of nanocarbide particles formed in Fe-Cr-W-V alloy were studied. A Fe-Cr-W-V alloy was first heat treated under different conditions. In this study, optical microscopy, scanning and transmission electron microscopy, x-ray diffraction, and hardness tester were used. The shape, size distribution, type, and lattice parameters of the extracted particles were investigated. The identified carbides were MC, M7C3, and M23C6. The particle size measurements showed that the mean length of carbide particles during 0.5, 5, and 20?h was about 103, 128, and 142?nm, respectively. Also, the mean thickness of carbide particles during 0.5, 5, and 20?h was about 54, 67, and 74?nm, respectively. |
