Hydrogen Diffusion and Its Effect on Hydrogen Embrittlement in DP Steels With Different Martensite Content

open access: yesFrontiers in Materials, 2020
The hydrogen diffusion behavior and hydrogen embrittlement susceptibility of dual phase (DP) steels with different martensite content were investigated using the slow strain-rate tensile test and hydrogen permeation measurement.

Interaction of martensite and bainite transformations and its dependence on quenching temperature in intercritical quenching and partitioning steels

open access: yesMaterials & Design, 2019
A series of quenching temperatures (QT) were applied to investigate the interaction of bainite and martensite transformations in intercritical quenching and partitioning steels with multiple-stage martensite transformation.

Discontinuous lath martensite transformation and its relationship with annealing twin of parent austenite and cooling rate in low carbon RAFM steel

open access: yesMaterials & Design, 2021
Lath martensite transformation in low carbon steel relates to the discontinuity of the transformation rate, which exhibits a series of martensite transformation rate maxima (peaks), especially in low cooling rates. In the present work, we put an emphasis

Kwinking as the plastic forming mechanism of B19 NiTi martensite [PDF]

open access: yesInternational journal of plasticity, 2023
Irreversible plastic forming of B19$^\prime$ martensite of the NiTi shape memory alloy is discussed within the framework of continuum mechanics. It is suggested that the main mechanism arises from coupling between martensite reorientation and coordinated

Controlling the work hardening of martensite to increase the strength/ductility balance in quenched and partitioned steels

open access: yesMaterials & Design, 2017
The role of retained austenite on tensile behavior in quenched and partitioned (Q&P) steels has been studied extensively, but the deformation behavior of martensite, which comprises the majority of Q&P microstructures, has received less attention.

Martensite plasticity and damage competition in dual-phase steel: A micromechanical experimental-numerical study [PDF]

open access: yesActa Materialia, 2022
Martensite damage in Dual-Phase (DP) steel has been studied extensively, yet, the exact deformation mechanisms that trigger or inhibit damage initiation remain mostly unexplored.

Effect of Silver Addition on Cu-based Shape Memory Alloys [PDF]

open access: yesChemical and Biochemical Engineering Quarterly, 2023
Shape memory alloys (SMAs) are smart materials with unique properties of superelasticity and shape memory effect. These properties are the consequence of thermoelastic martensitic transformation, which can occur under thermal or mechanical deformation ...

The Tapering Length of Needles in Martensite/Martensite Macrotwins

open access: yesArchive for Rational Mechanics and Analysis, 2023
AbstractWe study needle formation at martensite/martensite macro interfaces in shape-memory alloys. We characterize the scaling of the energy in terms of the needle tapering length and the transformation strain, both in geometrically linear and in finite elasticity.

Effect of Austenization and Repeated Quenching on The Microstructures and Mechanical Properties of Wear-Resistant Steel

open access: yesJournal of Materials Exploration and Findings, 2023
This study was focused on determining the effect of repeated austenitization and quenching on mechanical properties and microstructure. The experiment was carried out in a rolled quencher facility with a heat treatment process of one to two times, with ...

Dislocation densities in a low-carbon steel during martensite transformation determined by in situ high energy X-Ray diffraction

open access: yesMaterials Science & Engineering: A, 2021
The evolution of the dislocation densities in martensite and in austenite during the quench of a low-carbon (0.215 wt% C) steel is investigated in situ by the mean of a High Energy X-Ray Diffraction experiment on a synchrotron beamline.
