Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

open access: yessteel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

open access: yessteel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

open access: yessteel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

open access: yessteel research international, EarlyView.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

open access: yessteel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...
