Effect of Repeated Austenitisation and Cooling on the Microstructure, Hardness and Tensile Behaviour of 0.16 wt % Carbon Steel [PDF]

Archives of Metallurgy and Materials, 2018
Repeated austenitisation and furnace cooling of homogenised 0.16 wt. % carbon steels result in ferrite grain sizes between 27 μm and 24 μm. Similarly, repeated austenitisation and normal-air cooling produces ferrite grain sizes between 17 μm and 12 μm ...

Spatially Configuring RGO Interlayers With PANI/Lignin Nanoparticles Toward High‐Performance Asymmetric Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
A novel PLNPs@RGO electrode, self‐assembled from polyaniline/lignin conjugated mesoporous nanoparticles (PLNPs) and reduced graphene oxide, exhibits excellent capacitance and high energy density in supercapacitors. The high‐performance flexible solid‐state asymmetric supercapacitor (FSAC) plays a critical role in advancing the innovation of next ...

Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

steel research international, Volume 97, Issue 8, Page 4293-4305, August 2026.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

steel research international, Volume 97, Issue 8, Page 4316-4325, August 2026.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

steel research international, Volume 97, Issue 8, Page 4246-4260, August 2026.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Morphology and Formation of Chrysanthemum-like Pearlite in 100Mn13 Steel During Aging Treatment

Crystals
The morphology and microstructure of pearlite formed in 100Mn13 high-carbon high-manganese steel aged, respectively, at 525 °C and 650 °C after 1050 °C water toughening treatment were observed and analyzed by a scanning electron microscope (SEM) and ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

steel research international, Volume 97, Issue 8, Page 4270-4281, August 2026.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...
