前言 RA333(GH333)板材合金用于制造长期使用的地面和海上燃气轮机高温部件时,由于所用燃料品位低,燃气中常含有S、Na、K、V等离子,这就要求材料具有良好的抗热腐蚀性能。长期使用过程中还要求材料有一定的塑性和强度,而合金析出相的类型、分布和状态对合金性能产生重要的影响。本文就RA333(GH333)合金在900℃长期时效和在工况下长期运行后,碳化物的变化及其对合金塑性和强度产生的影响进行
Preface The use of RA333 (GH333) sheet alloys for the manufacture of long-term high-temperature components for surface and offshore gas turbines requires the use of S, Na, K, V in the gas due to the low grade of fuel used, which requires good hot corrosion resistance . Long-term use of the material also requires a certain degree of plasticity and strength, and the type of alloy precipitation phase, distribution and state of the alloy has an important impact on performance. In this paper, RA333 (GH333) alloy long-term aging at 900 ℃ and long-term operation under the conditions, the carbide changes and its plasticity and strength of the alloy produced
