The thermal stability of ball-milled nanocrystalline Sm2Fe17Cx interstitial compounds has been investigated. Sm2Fe17Cx decomposes into a mixture of phases upon annealing above a certain decomposition temperature, Td1, which depends on the carbon concentration in the compound. Annealing above a certain temperature Td2((approximately-greater-than)Td1), the Sm2Fe14C phase starts to form. The amount of the Sm2Fe14C phase increases with increasing annealing temperature at the expense of the Sm2Fe17 carbide until Tr1, at which temperature Sm2Fe14C starts to recombine with other phases to form the Sm2Fe17 carbide. For the starting composition with x〈1.5, the Sm2Fe17Cx single phase can be recovered above the recovery temperature Tr2((approximately-greater-than)Tr1). © 1996 American Institute of Physics.
