A qualitative study of multiphase steel microstructure developed in four different steel alloys [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy
In this work, quench and partitioning (Q&P) heat treatment was performed on four different steel alloys in order to obtain multiphase steels with a microstructure of ferrite, martensite, bainite, and retained austenite.

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.

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 ...

Phase field simulations of coupled phase transformations in ferroelastic-ferroelastic nanocomposites

open access: yes, 2009
We use phase field simulations to study composites made of two different ferroelastics (e.g., two types of martensite). The deformation of one material due to a phase transformation can elastically affect the other constituent and induce it to transform ...

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]

open access: yes, 2012
The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and

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

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

Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations

open access: yes, 2006
Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential features of the time-temperature-transformation (TTT) diagrams, continuous ...
