Abstract: A glassy Fe66Cr10Nb5B19 alloy and its crystalline counterpart consisting of the α-(Fe,Cr), FeNbB and Fe2B phases were spark plasma sintered with aluminum at 570 ◦C to investigate the interfacial reactions in the systems. In the mixture containing the crystalline alloy, α-(Fe,Cr) and Fe2B reacted with aluminum forming the Fe-Al intermetallic reaction products. The crystallites of FeNbB were distributed in the intermetallic matrix. The absence of α-(Fe,Cr) and Fe2B in the composite sintered from the glassy alloy was confirmed by Mossbauer ¨ spectroscopy. Overall, under the short SPS processing, the crystalline alloy was found to be more reactive towards aluminum than the glassy alloy. An increased reactivity was due to the presence of α-(Fe,Cr), a Fe-rich phase, in the crystalline alloy.
