摘要
nfluence of hot corrosion on the creep rupture behavior for both single crystal Ni-based superalloy DD3and specimens coated with Pt-Al was studied. In mixed salt, Pt-Al coating can improve creep properties of thealloy. The low melting point eutectic products lead to premature failure of alloy. This article proposes a newfracture model to explain the creep fracture behavior of DD3 at elevated temperature.
