Mechanical Property Comparison of AISI 5120 Steel Produced by LENS and DMD Systems

Engineering Reports, Volume 8, Issue 6, June 2026.
This study compares AISI 5120 steel produced by LENS and DMD processes, revealing trade‐offs in mechanical performance. LENS offers higher surface hardness and impact toughness, while DMD provides superior tensile strength and ductility. Findings guide process selection for application‐specific needs in automotive, aerospace, and heavy machinery ...

Mechanism of Inverse Bainitic Transformation in High Carbon Steels

, 2019
The formation of bainite is the most studied and the most debated phase transformation in steels, with research spanning almost a century. With two theories of transformation, the transformation mechanism of bainite is still a disputed subject among ...

Improving strength and ductility via ausforming combined with austempering through deformation-induced bainite refinement

Journal of Materials Research and Technology
The refinement of bainitic ferrite laths is one of the most critical ways to improve the combination of strength and ductility. However, low-temperature bainitic transformations in the microstructural evolution of carbide-free bainite in high-carbon ...

Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

steel research international, Volume 97, Issue 6, Page 3308-3327, June 2026.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

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.

The Acceleration of Phase Transformation and Strength–Toughness Match by Cerium Addition for Low‐Temperature Bainite

Rare Metals, Volume 45, Issue 5, May 2026.
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.

The Effect of Bainitic Transformation on Martensite Start Temperature of a Fe-C-Mn-Si Alloy

, 2011
The martensite start temperature (Ms) of a Fe-0.40%C-1.87%Mn-1.65%Si alloy with bainite and martensite dual phases was studied. The phase transformation dilation curves were measured and Ms temperatures of deformed and non-deformed specimens were ...
