Unraveling the Effect of Tramp Elements on Phase Transformations in Steels by Combining CALPHAD Modeling and Experiments

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.

Fatigue Crack Growth Behavior due to the Localized Compressive Deformation on Structural Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1597-1609, May 2026.
ABSTRACT The localized compressive deformation (LCD) process was used to analyze the fatigue crack growth behavior of a high‐strength low‐alloy structural steel. Eccentrically loaded single‐edge crack tension specimens (ESE(T)) in accordance with standard ASTM E647 were precracked at a crack length of about 4 mm from the machined notch by applying a ...
