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

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.
