Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Rational Design of Multifunctional Nano–Architected Coatings for Bipolar Plates in Proton Exchange Membrane Fuel Cells

Rare Metals, EarlyView.
ABSTRACT Proton exchange membrane fuel cells (PEMFCs) require advanced bipolar plate coatings to enhance efficiency, durability, and commercialization potential. This review presents a systematic framework for evaluating and designing bipolar plate coatings, integrating material selection, performance metrics, deposition techniques, and future ...

Influence of cementation duration on the structure and properties of structural middle carbon steel 40Cr4, 35CrMnSi4 and 42CrMoS4

Литьë и металлургия
The influence of increasing the cementation duration from 8 to 12 hours with subsequent quenching and low‑temperature tempering on the structure formation and contact fatigue of structural medium‑carbon low‑alloy steels 35CrMnSi4, 40Cr4, and 42CrMoS4 ...

Quenching and Partitioning of Multiphase Aluminum-Added Steels

Metals, 2019
The quenching and partitioning response following intercritical annealing was investigated for three lean TRIP-type high-Al steel compositions. Depending on the intercritical austenite fraction following annealing, the steels assumed either a ferrite ...

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

Surface and Interface Analysis, EarlyView.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.
