Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling [PDF]

Materials & Design, 2014
The effect of pearlite microstructure characteristics on strength and deformation of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar spacing on the ferrite plasticity parameters and residual stress induced by plasticity.

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.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

An Experimental and Computational Framework to Investigate the Microstructural Effects on the Mechanical Properties of Pearlitic Steels

Advanced Engineering Materials, Volume 27, Issue 2, January 2025.
A robust computational framework is proposed, which is designed to simulate microstructural‐scale plastic deformation and damage in pearlitic steels. The framework is calibrated and validated using experimental data from pearlitic steel rail samples. Subsequently, it is employed to investigate the impact of microstructural parameters, such as cementite

Application possibility of arc welding processes for long butt joint of 75Mn steel plates without preheating

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
An arc welding process for long butt joint of high carbon −75Mn steel plates without preheating was selected, assuring quality of weld and productivity. Abstract In order to ensure the stability of the track mechanical device, this paper solves the problem of attaching the lock flange to the side of the rail.

Co‐Deformation in Severely Deformed Multiphase Crystalline Metallic Systems: Physical Mechanisms, Intrinsic Limitations, and Perspectives

Advanced Engineering Materials, Volume 26, Issue 19, October 2024.
Taking advantage of co‐deformation mechanisms is a promising way to achieve fine grain metal matrix composites or architectured structures with unique properties. Understanding physical mechanisms is critical to promote refinement or fragmentation or mechanical mixing.
