Segregation of Fe during the sintering of doped W–Cu Alloys

In Fe dilute W–Cu alloys, the Fe distribution in W and liquid Cu, and the Fe interfacial segregation are studied by a thermodynamic approach and by energy dispersive analysis in transmission electron microscopy. The results show the preferred Fe distribution in liquid Cu and some Fe segregation in W...

Description
Summary:In Fe dilute W–Cu alloys, the Fe distribution in W and liquid Cu, and the Fe interfacial segregation are studied by a thermodynamic approach and by energy dispersive analysis in transmission electron microscopy. The results show the preferred Fe distribution in liquid Cu and some Fe segregation in W grain boundaries.
