摘　　要：研究了新型双相铸造不锈钢的化学成分、组织及其腐蚀与磨蚀行为。结果表明，该钢在含有固相颗粒的高温碱介质中具有良好的耐腐蚀与耐磨蚀性能。此外，还具有较好的力学性能和铸造性能，而且成本较低。The chemical composition of new type duplex phases cast stainless steel has been designedThe microstructure,corrosion behavior and erosion corrosion behavior of the steel were studiedThe experimental results show that this cast stainless steel has better corrosion resistance and erosion corrosion resistance can be used under the conditions of high temperature alkaine medium with solid grainsIn addition,the steel has good mechanical and casting properties,and lower cost,thus it is expected to be used to a wide application range
