Abstract

Fe-25Cr-5Mo-0.82C alloy was synthesized in an arc furnace in high purity argon atmosphere and crystallized on water-cooled copper mould. The cross section of the ingot was examined by light microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and its Vickers hardness determined. The microstructure is composed of primary and secondary dendrites Fe-Cr-Mo solid solution with equiaxed and elongated morphology, depending on the nature of the crystallization. In the interdendritic regions complex M23C6 carbides are present. The average hardness of the alloy is 264±5 HV10.

Keywords: Fe-Cr-Mo-C alloy, cast alloy, carbides, SEM, XRD
