The influence of coupling effect between stress and high temperature on the degradation of microstructure and hardness in P91 steel

Materials & Design
Interrupted aging and creep tests were performed in the condition of 650 °C/70 MPa for P91 steel. The mechanisms of hardness and microstructure evolution during aging and creep were studied through hardness test, SEM/EBSD and TEM/EDS.

Temperature-Dependent Fatigue Characteristics of P91 Steel [PDF]

Acta Mechanica et Automatica, 2020
Abstract In this paper, the experimental investigations, constitutive description and numerical modelling of low-cycle fatigue behaviour of P91 steel in non-isothermal conditions are presented. First, experimental tests are performed to recognise different aspects of material behaviour.

Electrochemical Hofmann Rearrangement for Modular Synthesis of Unsymmetrical Ureas and Late‐Stage Modification of Drugs

Advanced Science, Volume 13, Issue 31, 4 June 2026.
An electrochemical Hofmann rearrangement of amide involving amine or other amide nucleophiles has been developed. The use of NaI guarantees the feasibility and compatibility of the electrosynthesis protocol, which enables highly chemoselective synthesis of unsymmetrical N‐acylureas from two different amides, as well as the production of unsymmetrical ...

Atom Probe Tomography‐Based Analysis of Residual Trace Elements in Advanced Metallic Materials

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Residual trace elements inherited from raw materials strongly influence the mechanical and environmental performance of advanced metallic alloys and recycling materials due to preferable boundary/interface segregation and resultant embrittlement effects, yet their parts per million level concentrations pose significant challenges to ...

Electrochemical and Surface Insights Into X12CrMoWVNbN10‐1‐1 Steel Corrosion in Chloride Solutions at Variable pH

Materials and Corrosion, Volume 77, Issue 4, Page 518-528, April 2026.
The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
