Effect of Nb-V microalloying on low-cycle fatigue property of Fe-Mn-Al-C austenitic steel

Ting Zhao et al.

Summary: The tensile and low-cycle fatigue properties of Fe-Mn-Al-C austenitic steels with and without Nb-V microalloying are comparatively analyzed. The Nb-V microalloyed steel exhibits higher strength and lower elongation. It shows continuous cyclic softening behavior. The fatigue life of the Nb-V microalloyed steel is higher at strain amplitudes of 0.4% and 0.6%, but lower at 0.8%, compared to the non-microalloyed steel. The microstructures of the steels after fatigue testing exhibit parallel deformation bands composed of planar dislocations. The precipitation of (Nb,V) C positively influences the fatigue life improvement compared to k-carbides.

Precipitation of κ-Carbide in a V-Containing Austenite-Based Lightweight Steel

Mingxiang Liu et al.

Summary: The precipitation behavior of kappa-carbides in a Fe-20Mn-9Al-1.2C-1.0V austenite based lightweight steel has been studied. Cold rolling before aging precipitation can promote the precipitation of kappa-carbides and accelerate the eutectoid transformation of austenite. V element is slightly enriched in the region of kappa-carbides and affects the nucleation barrier energy. After annealing, precipitated V-carbides induce the subsequent precipitation of kappa-carbides in the form of band distribution.

The effect of Cr content on intragranular κ-carbide precipitation in Fe-Mn-Al-(Cr)-C low-density steels: A multiscale investigation

Jianlei Zhang et al.

Summary: The effect of Cr content on intragranular kappa-carbide precipitation behaviors in Fe-Mn-Al-Cr-C low-density steels was investigated. It was found that the volume fraction of kappa-carbides decreased and the growth rate slowed down with increasing Cr content. The precipitation temperature and temperature range of kappa-carbides were also affected by the increased Cr content. The presence of Cr atoms in the kappa-carbide structure increased interfacial energy and nucleation energy, making kappa-carbide formation more difficult. The increased interfacial energy, improved solubility of Al and C, and decreased diffusion coefficient of C in gamma-austenite caused by increasing Cr content resulted in a slower growth rate of the kappa-carbides.

Ultrahigh strength-high ductility 1 GPa low density austenitic steel with ordered precipitation strengthening phase and dynamic slip band refinement

L. L. Wei et al.

Summary: This article investigates the mechanical behavior of Fe-27Mn-9Al-1C austenitic steel microalloyed with Nb, specifically focusing on its work hardening behavior and plasticity mechanisms. The study reveals that pronounced planar dislocation slip occurs during plastic deformation, and the shearing of precipitates and refinement of slip bands contribute to strain hardening of the steel. Annealing twin boundaries act as dislocation sources, promoting further subdivision of slip bands and suppressing strain localization.

Strengthening κ-carbide steels using residual dislocation content

T. W. J. Kwok et al.

Summary: This study investigated the effect of hot rolling temperature on the mechanical properties of a Fe-28Mn-8Al-1.0C steel. It was found that lower temperature rolling significantly increased the yield strength without compromising the elongation to failure. The improvement in strength was attributed to the increase in residual dislocation density, which was retained even after the ageing heat treatment. The homogeneous precipitation of kappa-carbides indicated that the high residual dislocation density did not adversely affect precipitation kinetics.

Crystallographic texture evolution and martensite transformation in the strain hardening process of a ferrite-based low density steel

Mingxiang Liu et al.

Summary: The strain-induced martensite transformation plays a crucial role in the strain hardening process of low-density steel. This transformation is affected by the texture evolution and grain size of austenite, influencing the rate of martensite transformation in each stage of strain hardening. The presence of TWIP effect and high density dislocations during martensite transformation contributes to continuous hardening, but the final stage is slowed down by unfavorable orientation and reduced grain size of austenite.

Reverse partitioning of Al from κ-carbide to the γ-matrix upon Ni addition and its strengthening effect in Fe-Mn-Al-C lightweight steel

Chiwon Kim et al.

Summary: The study found that the addition of Ni to Fe-Mn-Al-C-Si-Mo cast lightweight steel led to simultaneous cooperative precipitation- and solid solution-strengthening after aging, effectively suppressing the movement of dislocations and contributing to continuous hardening. Atom probe tomography revealed that Al was preferentially enriched in the gamma-matrix in the aged 3Ni steel, with clustering of Ni atoms observed, indicating reverse partitioning of Al from kappa-carbide to the gamma-matrix through Ni addition. This study provides the first report of this phenomenon.
