| 摘要: |
| GH2132(A286)是析出强化型铁基高温合金,其含有多种合金化元素,为避免不合适的成分选择导致的综合性能失配,通过重点分析东北特钢提供的产品成分,解析国标成分区间的合理性,本文提出了一个更加合适的新成分标准形式。为此,引入“团簇加连接原子”结构模型,该模型将合金成分的结构载体表述为［中心-第一近邻］(连接原子)的团簇成分式形式。首先将合金化元素分为基体Fe、稳定奥氏体的(Ni,Mn)、稳定铁素体的(Cr,Mo,V,Si,Ti,Al)、以及不进入团簇式的(C,P,S,B)。通过分析国标规定的成分区间和实际合金成分,指出合金的实际成分区间远小于国标范围,并由16原子的成分式限定:Fe(8.5~9.0)±0.25(Ni,Mn)4±0.25(Cr,Mo,V,Si,Ti,Al)3~3.5。进而揭示了同类元素内部的质量百分比协同变化关系,即24.6≤Ni+Mn ≤28.0和17.4≤Cr+0.6Mo+V+1.7Si+1.1Ti+1.8Al≤20.4。由此更合理地限定Mn、Si元素成分区间,并对东北特钢的合金成分提供了改进建议。 |

| Abstract: |
| GH2132(A286) is an iron-based superalloy reinforced with γ′-Ni3(Ti, Al) phase,which contains multiple alloying elements.By investigating the composition of the product provided by Dongbei Special Steel Group and analyzing the reasonableness of the composition range in the international standard, this paper proposes a new composition standard form, aiming at avoiding the comprehensive performance mismatch caused by an inappropriate choice of composition. The “cluster-plus-glue-atom” model was employed,which identifies the structural carrier of the alloy composition and expresses as cluster formula ［center-nearest neighbors］(glue atoms). The alloying elements were first divided into matrix Fe, austenite stabilizers (Ni, Mn), ferrite stabilizers (Cr, Mo, V, Si, Ti, Al), and those that do not enter the cluster formula (C,P,S,B). By analyzing the elemental ranges specified in the international standard and the composition of some real alloys, it was pointed out that the actual composition range was far smaller than the international standard range, and was specified by 16-atom composition formula: Fe(8.5~9.0)±0.25(Ni,Mn)4±0.25(Cr,Mo,V,Si,Ti,Al)3~3.5. Then,the coordinated changes in weight percent within each classified element were unveiled: 24.6≤Ni+Mn ≤28.0 and 17.4≤Cr+0.6Mo+V+1.7Si+1.1Ti+1.8Al≤20.4. Thus, the composition ranges of Mn and Si were redefined, and suggestions were given to improve the product composition of Dongbei Special Steel Group. |
