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 ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

open access: yessteel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

EFFECTS OF TEMPERATURE ON AUSTENITIZING GRAIN SIZE STEEL 31CrMoV9

open access: yesЛитьë и металлургия, 2016
Austenitizing studied the effect of temperature on austenite grain size of the chrome-molybdenum-vanadium steel. It is shown that at austenitizing 850–1050ºS in the structure of chrome-molybdenum-vanadium steel nominal diameter of austenite grain varies ...

Micro‐Mechanism Informed Neural Networks for Process‐Property Prediction in Laser Powder Bed Fusion

open access: yesArtificial Intelligence for Engineering, EarlyView.
Hard physics embedding, where neural networks learn residuals relative to analytical baselines, substantially outperforms soft loss‐function constraints for extrapolation in LPBF process–property prediction. Physics integration architecture determines generalization capability more than constraint quantity.

Extraction replica method from thinned transmission electron microscopy samples without floating off carbon films: A case study on reduced activation steel

open access: yesJournal of Microscopy, EarlyView.
Abstract A recipe for producing carbon extraction replicas from twin‐jet electropolished disks is described. This technique allows tracking the analysed region with respect to the bulk sample. An example use of the method as applied to a reduced activation ferritic martensitic (RAFM) steel, ‘UK‐RAFM’, is reported.

Formation of Austenite Grains and Grain Boundary Segregation in Heating Process of Steel

open access: yesFormation of Austenite Grains and Grain Boundary Segregation in Heating Process of Steel
application/pdf The transforming process was traced on 1%Cr-0.5%Mo steel in the conditions of as-hot-rolled, quenched-and-tempered. The rapid heating process was employed from the viewpoint of weld thermal cycle. In as-hot-rolled specimen, austenite grain nucleates at ferrite/pearlite boundary, and grows into massive from.

High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2097-2115, June 2026.
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...
