摘要
高合金奥氏体不锈钢铸态组织中有σ相存在，经８５０～１１２０℃热处理所形成的σ相包括：（Ｆｅ－Ｃｒ）σ相、（Ｆｅ－Ｍｏ）σ相、以及（ＣｒＮｉＳｉ）σ相。８５０℃左右有Ｍ６Ｃ型碳化物和ＮｂＣ析出。该钢经１１５０℃×２ｈ水冷固溶处理后，具有优良的抗均匀腐蚀、晶间腐蚀、点蚀和化学腐蚀性能。
The σ pheses exist in as-cast structure of high--alloy cast austenitic stainless steel, σ pheses obtained by the heat treatment at 860～1120℃ include:(Fe-Cr) σ pheses, (FeMo) σ pheses and (CrNiSi) σ pheses. The M6C carbide and NbC have been precipitated at about 850℃, after solution treatment at 1150℃ for 2h WC,this steel prossesses good general corrosion,intergranular corrosion, pitting corrosion and electrochemical corrosion properties.
