The controlled phase transformation approach is a new generation of microstructure engineering for enhancing ductility in ultrafine-grained materials. The present study aims to extend this concept to dual-phase steel for enhanced tensile ductility at high strength. In this study, cold-rolled steel was...

A metastable CS-HEA with minimal void vol% was successfully fabricated using LPBF AM technique. As-printed ε-dominated columnar grained microstructure facilitated exceptional work hardening ability in CS-HEA, and thus resulted in very high strength-ductility synergy under tensile loading. The higher ...
Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility. Here, we review recent advances in overcoming this tradeoff, by purposely deploying heterogeneous nanostructures in an otherwise single-phase metal. Several structural designs are being explored, ...
PURPOSE: To produce a steel plate excellent in the balance of strength-ductility and workability by specifying its compsn. ;CONSTITUTION: Composition of this steel plate is constituted of, by weight, 0.002% C, 0.1 to 2.O% Si, 0.5 to 2.S% Mn, 0.03 to 0.20% P, ≤0.003% S,% 0.1...
The strength–ductility trade-off has been a long-standing dilemma in materials science. This has limited the potential of many structural materials, steels in particular. Here we report a way of enhancing the strength of twinning-induced plasticity steel at no ductility trade-off. After applying...
an effect referred to as the strength-ductility trade-off. This [work] studies the kinetics and thermodynamics of microstructural evolution of lightweight steels through simulations and experiments, and proposes a mechanism to achieve higher strength and larger ductility – a method that can be readil...
The strength-ductility synergy in TZK alloy was achieved by a combination of aging, extrusion and novel DT-ECAP process.The appearance of jogs or kinks highly contributed to the continued plastic straining during DT-ECAP process.The high strength originated from the strengthening mechanisms of grain...
