GH36合金在生产和使用中曾多次产生质量问题。本文探讨了使用质量和材质的关系表明:涡轮盘榫齿裂纹主要与第一是受力过大造成的,调整齿间距Δ=S 片-S盘为零或负值时,有效地消除了榫齿裂纹。涡轮盘槽底裂纹与合金的抗氧化、腐蚀(特别是晶界腐蚀)和冷热疲劳性能直接有关。文中论述了合金存在异金属夹杂、碳化物偏析、局部低倍粗大晶粒等在一定程度上影响合金的某项性能,但对零件使用还得分析具体使用条件,材质质量的类型、性质、程度以及分布部位等要区别对待。最后对质量应采取必要措施,既保证使用安金,又不浪费金属材料,提出了看法。
GH36 alloy has many times in the production and use of quality problems. This paper discusses the use of quality and material relations show that: the turbine disk tenon crack main and first is caused by excessive force, adjust the tooth spacing Δ = S-S disk is zero or negative, effectively eliminating the tenon Tooth crack. Turbine groove bottom crack and the alloy’s oxidation resistance, corrosion (especially grain boundary corrosion) and thermal fatigue properties directly related. In this paper, the existence of different metal inclusions, carbide segregation, local low-times coarse grains and so on to a certain extent, affect a certain performance of the alloy, but the use of parts have to analyze the specific conditions of use, the type of material quality, nature, extent And the distribution of sites to be treated differently. Finally, the quality of the necessary measures should be taken, both to ensure the use of Anjin, without wasting metal material, put forward their views.
