Influence of back tension on wire deformation heterogeneity and texture intensity: A coupled macro-micro calculation study

Journal of Materials Research and Technology
Pearlitic steel wires are typically produced through cold drawing process, where the wire is pulled through drawing dies by external forces, leading to diameter reduction and length elongation.

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

Strength Anisotropy and Residual Stress in Drawn Pearlite Steel Wire

ISIJ International, 2004
Strength anisotropy is found by tensile and compressive tests for a drawn pearlite steel wire, where the compressive tests are performed for prepared specimens along directions of 0, 45 and 90 degrees with respect to the drawing direction. The influence of annealing on such anisotropic strength is also examined. To make clear the origin of the strength

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.

Surface Functionalization of Novel Work‐Hardening Multi‐Principal‐Element Alloys by Ultrasonic Assisted Milling

Advanced Engineering Materials, Volume 26, Issue 20, October 2024.
Multi‐principal‐element alloys (MPEAs) with high work hardening capacity, like Hadfield steel, can extend conventional alloy systems. In this study, CoFeNi‐based MPEAs with Mn and C are cast and mechanically finished using ultrasonic milling. The resulting MPEAs show significant hardness increase and improved wear resistance, demonstrating their ...
