Experimental evidence is presented for trapping of Sb by TaC and Cu precipitates in Fe. These processes were studied during annealing at 873 K of Fe ion-implanted with either Ta, C, and Sb, or Cu and Sb. For both precipitates the derived binding enthalpy is approx.0.4 eV when referenced to an Sb solution site in the bcc-Fe phase. It is argued that this trapping occurs at the precipitate-host interface, and that it is due primarily to the associated structural discontinuity. In the Fe-Cu-Sb alloys, trapping was accompanied by two other processes which immobilize Sb, namely, dissolution into the fcc-Cu phase and formation of ..beta..-Cu/sub 3/Sb. The trapping effects observed in these studies are of potential significance for the control of Sb embrittlement in ferritic steels.
