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

ON NEW MATHEMATICAL METHODS OF ANALYSIS OF THE PEARLITIC STEELS EUTECTOID COLONIES MICROSTRUCTURE

Литьë и металлургия, 2008
Algorithms for mathematical description of microstructures of pearlitic steels is offered. It is shown that mathematical models of microstructures, built using frequency distribution of the eutectoid pearlitic steel colonies, allow to evaluate the degree

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 ...

Microstructure and wear resistance of high-carbon pearlitic CrMo wear-resistant cast steels containing submicron-sized precipitates

Journal of Materials Research and Technology
Vanadium (V) plays a crucial role in the formation of precipitates. In this study, different amounts of submicron-sized precipitates were introduced in high-carbon pearlitic CrMo wear-resistant cast steel by the addition of V.

Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

steel research international, Volume 97, Issue 8, Page 4067-4084, August 2026.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Prediction of critical cooling rate under rapid heating rate and short holding time for pearlitic rail steel

Journal of Materials Research and Technology
Critical cooling rate (Vc) is typically employed to assess the ability of forming martensite for pearlitic railway steels. Currently, the examination of Vc is normally conducted by dilatometry analysis under a fully austenitizing condition.
