A new approach to modeling the flow curve of hot deformed austenite

A new, more physically realistic and practically useful model is presented for the simulation of high temperature austenite flow curves. It is an extension of our earlier empirical model based on the Avrami kinetics of dynamic recrystallization. In the new ...

Laminated Metal Composites by Infiltration

Andreas Mortensen, Andreas Rossoll, Jérôme Krebs, Arda Cetin, Alexandre Durussel

We show that steel-magnesium alloy laminated metal composites (LMCs) can be produced by gas pressure infiltration of a liquid magnesium alloy between layers of stacked dimpled steel sheets. Resulting LMCs are amenable to subsequent warm rolling. The LMCs a ...

Quasi In situ EBSD investigation of static recrystallization in 304L stainless steel at elevated temperature

Roland Logé, Ke Huang

The microstructural evolution of deformed 304L stainless steel during static recrystallization and grain growth was characterized by EBSD within an SEM chamber, which enabled microstructural and crystallographic information to be determined. The experiment ...

Effect of thermo-mechanical treatments on the microstructure and mechanical properties of an ODS ferritic steel

Philippe Spätig, Nadine Baluc, Zbigniew Oksiuta, Pablo Federico Mueller

The Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steel was fabricated by mechanical alloying of a pre-alloyed, gas atomised powder with yttria nano-particles, followed by hot isostatic pressing and ther ...

Influence of hot rolling and high speed hydrostatic extrusion on the microstructure and mechanical properties of an ODS RAF steel

Nadine Baluc, Zbigniew Oksiuta

An argon gas atomized, pre-alloyed Fe-14Cr-2W-0.3Ti (wt.%) reduced activation ferritic (RAF) steel powder was mechanically alloyed with 0.3wt.% Y2O3 nano-particles in an attritor ball mill and consolidated by hot isostatic pressing at 1150 °C under a press ...

Theoretical and experimental evaluation of the formability of anisotropic zinc sheets

Roland Logé

Formability of metal sheet has been widely studied for the past 40 years. This study leads to the well known Forming Limit Diagram (FLD) proposed by Keeler and Backhofen [1]. Such a diagram needs typical drawing and stretching experiments to be achieved. L ...

Identification of cyclic and anisotropic behaviour of ODS steels tubes

Roland Logé

In this paper, an elastic plastic behaviour model based on internal state variables is investigated. The final aim is to describe the mechanical stress-strain cyclic response of oxide dispersion strengthened (ODS) steels during the cold pilgering process. ...

Towards the modelling of recrystallization phenomena in multi-pass conditions: application to 304L steel

Ke Huang

Recrystallization, which can occur dynamically or statically, is an important phenomenon causing microstructure changes in deformed metals and therefore affecting the properties of the material. Even though extensive investigations have been carried out on ...

Fast-curing coatings for adhesion promotion between metallic oxides and thermoplastic polyurethane

Véronique Michaud, Basile Golaz

The cost-effective production of high-performance and durable steel reinforced thermoplastic composites requires improvement of the adhesion encountered at the interface between metallic substrates (galvanized steel) and a thermoplastic elastomer (TPU). Co ...

About the possibility of grain boundary engineering via hot-working in a nickel-base superalloy

Roland Logé

Microstructures, and especially grain boundary populations, are characterized in a γ/γ′ nickel-base superalloy submitted to various thermomechanical treatments involving hot deformation and subsequent supersolvus annealing. The resulting microstructures co ...
