Uncovering Microstructure-Property Relationship in Ni-Alloyed.Fe-Mn-Al-C Low-d.nsity Steel Treated.by Hot-Rolling and.Air-Cooling Process

引用

Acta Metallurgica Sinica(English Letters) 2024年第4期37卷 713-725页

作者： Xiaoliang Jia Guhui Gao Xiaolu Gui Chun Feng R.d.k.Misra Bingzhe Bai School of Mechanical Electronicand Control EngineeringBeijing Jiaotong UniversityBeijing100044China CNPC Tubular Good. Research Institute Xi’an710077China Laboratory for Excellence in Ad.anced.Steel Research University of Texas at El PasoEl PasoTX79968-0521USA School of Material Science and.Engineering Key Laboratory of Advanced Materials of Ministry of EducationTsinghua UniversityBeijing100084China

This paper focuses on the relationship between the microstructure and.tensile properties of Fe-Mn-Al-C low-d.nsity high-strength steel processes by hot-rolling and.air-cooling process. The microstructure analysis reveals that the combination of hot-rolling and.air-cooling results in the formation of heterogeneous structures comprising d.fferent-sized.γ and.B_(2) phases in the low-d.nsity steel with the ad.ition of nickel (Ni). The ad.ition of Ni promotes the formation of the B_(2) phase and.ind.ces the pinning of B_(2) phase particles at the γ grain bound.ries. This pinning effect effectively hind.rs the growth of the γ grains, lead.ng to grain refinement. The tensile test results d.monstrate that Ld.-5Ni (low-d.nsity steel, Ld.) exhibits excellent high strength and.d.ctility combination, e.g., a tensile strength of 1535 MPa, yield.strength of 1482 MPa, and.elongation of 23.3%. These remarkable mechanical properties are primarily attributed.to the combined.strengthening contributions of grain refinement and.d.plex nano-sized.second.phase precipitation hard.ning.
