“…The presence of the thermal martensite in ADSS has already been evidenced and discussed in our previous work [25] and its contribution to the mechanical behavior could be significant in composites n (i>1), since the fraction of martensite increases together with the interfacial area between ferrite and austenite, and with the extent of interdiffusion.…”

“…no transformation to martensite has occurred. In addition, these results show that the stability of the austenitic phase is not significantly disrupted by the changes in the chemical composition of 316L due to interdiffusion of solute elements during the annealing steps [25].…”

“…The Architectured Duplex Stainless Steels (ADSS) samples were prepared using the Accumulative re-Bundling and Drawing (ABD) process, described in detail in our previous work [25]. Commercial austenitic and ferritic stainless steels of grades respectively 316L AISI (UGIMA® -X 4404) and 430LNb AISI (UGIMA® 4511) provided by UGITECH, have been used in elaborating ADSS wires of diameter of 1.55 mm.…”

“…In the present work, we investigate the mechanical behavior of DSS wires produced by Accumulative re-Bundling and Drawing (ABD), following our previous description of this material processing [25]. We evidenced in [25] a systematic increase in the yield strength, as a function of the manufacturing step, independently from the phases' volume fraction. An indepth analysis has been conducted here to investigate the different hypotheses and to rationalize the resultant mechanical behavior from that of each constitutive phase.…”

“…These fractions are calculated by assuming that the martensite is formed within a constant layer within the vicinity of ferrite/austenite interface and inside 316L phase. The thickness of this layer was taken to be the maximum observed by EBSD and TEM [25], namely 3µm.…”

The mechanical behavior of micro-composites Duplex Stainless steels (DSS) produced by Accumulative re-Bundling and Drawing (ABD) has been investigated. We evidenced a systematic increase in the yield strength, as a function of the manufacturing step, independently from the phases' volume fraction. A simple rule of mixture (ROM) successfully predicted the first generation of composites presenting a simple microstructure. However, a modified ROM taking into account the contribution of each component and its grain size could not predict the mechanical response of the composites of higher generation. An in-depth analysis is conducted to investigate the microstructure-mechanical behavior relationship and to rationalize the resultant mechanical behavior from that of each constitutive phase. For this purpose, in-situ synchrotron High Energy X-ray Diffraction measurements during uniaxial tensile experiments have been carried out to calculate the strain partitioning within each phase of the composites.

Improving the strength‐to‐ductility trade‐off remains the prime driving force for the development of advanced high‐strength steel. Traditionally research breakthroughs are focused on the microstructure and relative phase composition. Herein, laser hardening is applied to ductile ferritic steel to introduce straight and corrugated martensitic reinforcements, effectively generating architectured steel sheets. Tensile behavior of laser‐architectured samples is studied both using finite‐element method simulation and mechanical testing to reveal the effect of laser‐induced corrugations on strength and necking strain. The results show that with the same reinforced volume fraction of 24%, an increase in corrugation height/period leads to a gain in necking strain with a loss in yield strength and ultimate tensile stress. This beneficial effect on necking strain is due to the corrugation unbending process which introduces so‐called geometric work hardening during tension. Extended simulations are carried out on various corrugation heights/periods and the evolution trends of ultimate tensile strength and necking change with different reinforced volumes. This study proposes a perspective on corrugation‐reinforced architectured materials. Corrugation parameters can be chosen to tailor the mechanical behavior of laser‐architectured materials.
