Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

steel research international, Volume 97, Issue 6, Page 3308-3327, June 2026.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

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

Fatigue &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 ...

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...
