Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Role of Aluminide Coating on Oxidation Resistance of Ni-Based Single Crystal Superalloy at 900 °C

International Journal of Electrochemical Science, 2015
In the present study, the role of aluminide coating on oxidation resistance of Ni-based single crystal superalloy was studied at 900 °C. The oxidation kinetics curves obey the parabolic law in both conditions.

Computational Tools for Designing Ni-Base Superalloys

Superalloys 2004 (Tenth International Symposium), 2004
The main objective of this work is to develop a set of integrated computational tools that can be employed to design Ni-base superalloys. In particular, we developed reliable thermodynamic, kinetic and lattice parameter databases for the Ni-Al-Mo superalloys by combining first-principles calculations and CALPHAD (CALculation of PHAse Diagrams ...

Effect of the Fe Content on the Oxide Film Composition and Corrosion Resistance of Inconel 625: An XPS and Cyclic Potentiodynamic Polarisation Study

Surface and Interface Analysis, Volume 58, Issue 3, Page 151-163, March 2026.
ABSTRACT The present work focuses on investigating the effect of increasing Inconel 625 Fe content on the oxide film composition and corrosion behaviour through XPS and cyclic potentiodynamic polarisation (CPP) studies. Different proportions of ASTM A182 F22 steel and Inconel 625 were arc‐melted to achieve a range of Fe contents (2–15 wt.%) in the ...

Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.
