摘要: FeCrAl alloys are proposed candidate materials for liquid lead applications. Chromium is needed to assist the formation of a protective alumina layer, albeit has be limited avoid α′ precipitation. Reactive elements (RE) improve oxidation properties, but little known about RE effects at lower temperatures. An alloy matrix based on Fe–10Cr–4Al (wt%), with varying Zr, Y and Ti contents, was exposed up 1 year in temperature interval 450–550 °C. It found that dependent RE/carbon ratio. All ratios than unity showed poor properties due Cr-carbides metal–oxide interface. A sufficiently high amount Zr shown significantly both The positive effect related suppression by addition stronger carbide formers.
