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.

ABSTRACT The engineering application of traditional nano‐bainite steel, also known as low‐temperature bainite steel, has been restricted due to its relatively low toughness and the prolonged isothermal transformation time during manufacturing processes.

Effect of Two-Step Austempering Process on Transformation Kinetics of Nanostructured Bainitic Steel [PDF]
The two-step austempering process has been reported to be an effective method to accelerate the bainitic transformation process by introducing martensite (Q-M-B). However, in this study, it was found that the Q-M-B process reduced the incubation time, but the transformation duration remained nearly unchanged.

Formation of bainite below martensite start temperature in quenching low carbon steel
According to the phase transformation kinetics that we recorded by dilatometry in rapid cooling of low carbon steel, some amount of isothermal bainite appeared in the middle of martensitic temperature range.

Here, the microstructure evolution of a new generation ultrahigh‐strength S1300‐type structural steel has been investigated for direct‐quench and tempering route. Various stages of tempering are elucidated by thorough characterization, and a new strain‐size parameter of martensite is proposed to have a correlation with hardness, which will be useful in

New Model for the Overall Transformation Kinetics of Bainite. Part 2: Validation
A new model for the overall kinetics of the bainite transformation has been validated experimentally. The new model, presented in the 1st part of this work, is based in the displacive mechanism for bainite transformation. Thus, the bainite transformation kinetics of three medium carbon-high silicon steels has been studied.

Upper to Lower Bainite Transition in a High-Carbon Low Alloy Steel: Linking Overall Transformation Kinetics, Microstructure and Microhardness [PDF]
The transition from upper-to-lower bainite in carbon steels is a complex process yet not fully explored. This study examines such transition in a 0.7C, 0.74Mn, 0.61Si, 0.2Cr (wt%) low-alloy steel using a comprehensive approach that integrates dilatometry,

ABSTRACT High‐entropy alloys (HEAs) exhibit exceptional mechanical properties under cryogenic conditions, defying the conventional strength‐ductility trade‐off observed in traditional metal. This review systematically consolidates recent advancements in understanding the deformation mechanisms, microstructural dynamics, and anomalous mechanical ...
