Electrochemical hydrogen charging of duplex stainless steel [PDF]

, 2019
This study evaluates the electrochemical hydrogen charging behavior and interaction between hydrogen and the microstructure of a duplex stainless steel. A saturation level of approximately 650 wppm is reached after 10 d of charging. The data are compared

Investigation on austenite transformation in continuously cast steel based on dilatometry and the phase fraction model

工程科学学报, 2015
To understand the knowledge of liner thermal expansion and thermal expansion coefficient of Q450NQR1 casting steel, dilatometry experiments were performed at two different cooling rates of 5℃·min-1 and 20℃·min-1.

In Situ Determination of Phase Stress States in an Unstable Medium Manganese Duplex Steel Studied by High-Energy X-ray Diffraction

Metals, 2020
Duplex medium Mn steels are high-potential advanced high-strength steels (AHSS) for automotive construction. Their excellent forming properties stem from the specific stress partitioning between their constituting phases during deformation, namely the ...

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

, 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 ...

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

, 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 ...

Prediction of the mechanical behaviour of TRIP steel [PDF]

, 2011
TRIP steel typically contains four different phases, ferrite, bainite, austenite and martensite. During deformation the metastable retained austenite tends to transform to stable martensite.
