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‐

Comparison of Novel 1 GPa Low‐Carbon, Low‐Alloyed Steel Produced with Simulated and Laboratory‐Scale Thermomechanical Controlled Processes

steel research international, Volume 96, Issue 3, March 2025.
A laboratory‐scale hot‐rolled Ti–Mo–V–Nb steel with 1 GPa tensile strength is produced, and its microstructure and tensile properties are characterized using advanced analysis techniques and tensile testing. A Gleeble 3800 thermomechanical simulator is used to determine a process window. Results show significant differences in mechanical properties and

A Physically Based Mean Field Model for Strain‐Induced Precipitation and Recrystallization in High‐Strength Low‐Alloy Steels

steel research international, Volume 96, Issue 1, January 2025.
A physically based mean field model is employed to describe the microstructural evolution during the thermomechanical control process of X70 high‐strength low‐alloy steels, due to the interaction between strain‐induced precipitation of niobium and titanium carbonitrides and static recrystallization of austenite.
