The precipitate particles formed during several heat treatments consisting of solution, air-cooling, and high-temperature tempering in reduced activation Fe – Cr – W – V – C alloy were investigated. The morphology and structure of the precipitate particles formed in the matrix of the alloy were evaluated by means of metallography, transmission electron microscopy (TEM), x-ray diffraction (XRD), and scanning electron microscopy (SEM) after tempering at 600°C for 5 and 20 h. Hardness measurements of the specimens were also done. The combination of these techniques provided new insights into how different precipitate morphologies may form during different heat treatments. The results showed that two types of particles were mainly precipitated, M7C3and M23C6, were in spherical and blocky shapes.
