Training-Induced Criticality in Martensites [PDF]

open access: yesPhysical Review Letters, 2007
We propose an explanation for the self-organization towards criticality observed in martensites during the cyclic process known as `training'. The scale-free behavior originates from the interplay between the reversible phase transformation and the concurrent activity of lattice defects.

Lattice deformations at martensite-martensite interfaces in Ni-Al [PDF]

open access: yesLe Journal de Physique IV, 2001
The atomic configurations at macrotwin interfaces between microtwinned martensite plates in $Ni_{65}Al_{35}$ material are investigated using high resolution transmission electron microscopy (HRTEM). The observed structures are interpreted in view of possible formation mechanisms of these interfaces.

Application of Virtual Reality for Learning the Material Properties of Shape Memory Alloys

open access: yesApplied Sciences, 2019
A shape memory alloy (SMA) is an alloy which can eliminate deformation at lower temperatures and restore its original shape upon heating. SMAs have been receiving considerable attention in the research field of materials science, and their applications ...

Martensite tempering kinetics: Effects of dislocation density and heating rates

open access: yes, 2020
In this study, the combined effect of dislocation density and rapid thermal cycling on the tempering kinetics of fully martensitic steel has been investigated by straining the sheets to different deformation levels.

Deformation behavior of duplex austenite and ε-martensite high-Mn steel

open access: yesScience and Technology of Advanced Materials, 2013
Deformation and work hardening behavior of Fe–17Mn–0.02C steel containing ε-martensite within the austenite matrix have been investigated by means of in situ microstructural observations and x-ray diffraction analysis. During deformation, the steel shows

The effect of reversed austenite on mechanical properties of 13Cr4NiMo steel: a CPFEM study

open access: yesJournal of Materials Research and Technology, 2022
In order to investigate the effect of reversed austenite on the mechanical properties of 13Cr4NiMo steel, a meso scale crystal plasticity finite element model (CPFEM) was established to simulate the deformation induced martensitic transformation (DIMT ...

Mechanical and tribological behavior of dual-phase ductile iron with different martensite amounts

open access: yesJournal of Materials Research and Technology, 2023
Ferrite-martensite (F/M) dual-phase ductile iron with different relative amounts of martensite was fabricated via intercritical quenching in the present study. The mechanical properties and tribological behavior were investigated. The strength of ductile

Strain hardening behaviour of as-quenched and tempered martensite

open access: yes, 2020
Martensite is a key constituent in advanced high strength steels and plays an important role in providing the high strength. While the strength of martensite has been extensively studied in the past, its low elastic limit and extremely high strain ...

Crystallographical Analysis on Martensite Transformation and Martensitic Morphology.

open access: yesISIJ International, 1997
The strain tensor and displacement vector associated with lattice deformation were introduced to discuss the effect of self-accommodation and plastic accommodation in martensitic transformation and the crystallographic models for {557} f , {225} f and {31015} f martensite were proposed, along with their experimental verification.
