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.

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Evolution of crystallographic texture and material anisotropy effects resulting from uniaxial deformation for high‐strength steels with high manganese content

Journal of Applied Crystallography, Volume 59, Issue 1, Page 163-178, February 2026.
The present study investigates the deformation behavior of high‐strength steels and the associated evolution of material anisotropy. Particular focus is placed on the impact of crystallographic texture and intergranular strains on how residual stresses can be evaluated using X‐ray diffraction and the associated assessment of weld seams in the ...

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Synchrotron Diffraction Study of the Cementite Phase in Cold Drawn Pearlitic Steel Wires [PDF]

Materials Science Forum, 2013
Energy dispersive synchrotron diffraction has been carried out on cold drawn pearlitic steel wires. In this paper the observed cementite peaks are analysed. For a broad range of true drawing strains sin²(Ψ) curves have been measured. The residual stress in the cementite is found to saturate after reaching a maximum at a strain of about 1.6.

Microstructural Evolution, Performance, and Triboelectric Response of Cu–Fe Composites Processed via Deformation‐Driven Metallurgy

Engineering Reports, Volume 7, Issue 10, October 2025.
Microhardness reached a maximum of 158.5 ± 3.9 HV at 4 wt.% Fe, with tensile strength peaking at 331.9 ± 9.9 MPa, whereas higher Fe addition (6 wt.%) caused microhardness and tensile strength to decline to 142.4 ± 4.8 HV and 294.7 ± 9.2 MPa, respectively, due to particle clustering and thermal softening.
