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

Surface and Interface Analysis, Volume 58, Issue 4, Page 246-261, April 2026.
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.

Fatigue of Martensite-Ferrite High Strength Low-alloy Dual Phase Steels.

ISIJ International, 1999
Fatigue tests were carried out with as-rolled and heat-treated Si-Mn-Cr-Mo martensite-ferrite dual-phase steels at room temperature in air and 3.5% NaCl solution. The effects of duplex microstructural morphologies, martensite contents and environmental conditions on fatigue stress-life, cyclic deformation behavior, fatigue crack initiation and near ...

On the Impact Energy Absorption of an Advanced High‐Strength Bilayer Steel Composite Consisting of Carbide‐Free Bainitic Steel and High‐Mn Twinning‐Induced Plasticity Steel

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Design of a Cobalt‐Free Maraging Steel with Ultra‐High Strength of 2.3 GPa Through Additive Manufacturing

Advanced Science, Volume 13, Issue 16, 18 March 2026.
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...
