Constitutive Modeling of High-Strength Steel Designed for Ballistic Protection

EPJ Web of Conferences, 2018
Constitutive behaviour of a high-strength nanostructured bainitic steel NANOS-BA® was investigated in the article. A few types of mechanical tests under varying strain rates were carried out to determine the values of constants of Johnson-Cook flow and ...

Impact of Partitioning Temperature Parameters during the Quenching and Partitioning Process on Medium Carbon Steels with Two Different Alloying Strategies

steel research international, Volume 96, Issue 6, June 2025.
The study investigates microstructural evolution during high‐temperature partitioning in medium‐carbon, high‐silicon aluminum‐aided steels, exploring phase transformations affecting the final microstructure. Quenching and partitioning processes, with varying primary martensite fractions, reveal significant austenite stabilization at 350 °C, but ...

From Nanoindentation to Microhardness to Tensile Strength: Correlation Coefficients Estimates as a Function of Microstructure in Eutectic SnBi Alloy

Engineering Reports, Volume 7, Issue 4, April 2025.
Our manuscript focuses on the correlation between nanohardness, microhardness, and macroscopic tensile strength—an area of increasing industrial demand, especially considering advent to miniaturization of all electronic components and non‐destructive testing. The material selected for this study stems from the microelectronic industry's pursuit of lead‐

Formation of Bainite in a Low‐Carbon Steel at Slow Cooling Rate – Experimental Observations and Thermodynamic Validation

steel research international, Volume 96, Issue 2, February 2025.
A low‐carbon (0.23 wt%) carbide‐free bainitic steel is successfully developed with a total alloying addition of 4.9 wt%, which is relatively lower than alloying additions reported in similar category of steels. The present findings indicate that the currently designed low‐alloy steel composition is amenable to generation of nearly carbide‐free bainitic

Short fatigue crack growth in an artificial-defect-containing nanostructured bainitic steel [PDF]

, 2023
For a full exploitation of novel steels in applications under mechanical cyclic loading, it is vital to understand the crack-microstructure interactions. In this work, the fatigue behaviour of a nanostructured bainitic steel in the short crack regime has

Heterostructured Metallic Structural Materials: Research Methods, Properties, and Future Perspectives

Advanced Functional Materials, Volume 34, Issue 51, December 16, 2024.
Heterostructured materials (HSMs) are becoming an emerging strategy for superior mechanical properties of metallic materials. Comprehensive evidence is necessary to substantiate their feasibility. This study provides an extensive review of experimental results from worldwide research groups across titanium, magnesium, aluminum, copper, steel, and ...

Influence of Ausforming on the Micro‐ and Nanostructure of PH 13‐8 Mo Maraging Steels

steel research international, Volume 95, Issue 8, August 2024.
The potential of the integration of ausforming into the heat treatment of PH 13‐8 Mo maraging steels is investigated. By performing ausforming, a refinement of martensite is achieved. Furthermore, the high number of induced nucleation sites can elevate the number density of β‐NiAl precipitates after aging.

Effect of retained austenite on adhesion-dominated wear of nanostructured carbide-free bainitic steel [PDF]

, 2020
Sliding wear performance of carbide-free bainitic steel is significantly affected by microstructure. This investigation is an attempt to find a correlation between microstructure and wear resistance of carbide-free bainitic steel and compare the results ...

Microstructure evolution during tensile deformation of a nanostructured bainitic steel [PDF]

Scripta Materialia, 2013
In situ neutron diffraction was used during tensile testing at room temperature to examine the changes in the proportion and texture of both ferrite and austenite in a nanocrystalline bainitic steel transformed at two different temperatures, 200 and 300 C, for different times to achieve the same phase percentages.
