TEM characterization of precipitates in EUROFER 97

The spatial distribution, morphology, structure and chemical composition of different precipitates and inclusions in 9%Cr reduce activation ferritic–martensitic steel known as EUROFER 97 has been studied using transmission electron microscopy (TEM). The EDX, EELS analyses as well as HRTEM imaging and electron diffraction have been applied for imaging, analysis and identification of the M23C6 precipitates and MX particles, which were identified as TaC, VN, and TiC. Their influence on the formation of microstructure has been discussed. A detailed characterization of complex precipitates with TiC core is reported.
