List of symposia

The conference will comprise a few plenary lectures, followed by 4 to 5 parallel sessions with invited and regular talks.

A poster session will be held, preceded by a short presentation of all posters by their author during dedicated sessions. Poster prizes will be attributed.

The organization of abstracts will follow the following list of symposia, with the associated scientific commitee:

1. Phase transformations 

P. Donnadieu, W. Lefebvre, M. Perez, C. Sigli

This symposium will provide an international forum for experimentalists and theoreticians working in the field of solid-state phase transformations of aluminum alloys. Participants will describe new theories/simulations describing the complex interactions between aluminum and the solutes during heat treatments and processing.  They will also describe key experiments which unravel the physics behind phase transformation or provide new quantitative microstructure characterizations which serve as benchmark for the simulations.

2. Strength, plastic deformation & formability 

A. Deschamps, F. Mas, T. Morgeneyer

The symposium will focus on all aspects of strength, plastic deformation, and their consequences on formability of aluminium alloys for different fields of applications (aerospace, automotive, beverage cans…). This will include but not be limited to research identifying the microstructure / strength relationships, constitutive laws, linking the effect of microstructure and texture on strain heterogeneity, plastic localization and associated damage development. Both experimental and computational studies are in the scope. For instance, studies using innovative characterization techniques in order to assess the interactions between dislocations and microstructural features (TEM, EBSD…), to measure the evolution of strain distribution in different stress states (in-situ fields measurements) and to detect the onset of damage (tomography…) are particularly well suited for this symposium. Multi-scale models, and especially those accounting for microstructural aspects are highly welcome: they range from dislocation dynamics and crystal plasticity to instability criteria for flow localization and sheet necking together with forming limit diagram predictions and finite element simulations of forming operations. New emerging forming technologies and their applications to aluminium alloys are also part of this symposium.

3. Durability: fatigue, fracture, corrosion & surface treatments 

C. Blanc, J.Y. Buffière, J.C. Ehrström

The symposium covers all aspects related to the durability of Al alloys and their behavior under severe service loads and environments, with or without  coupling conditions. Characterization of  the mechanisms controlling fatigue and fracture, corrosion, environmentally assisted cracking, but also creep and high temperature behavior belong to the scope of this symposium as well as protection against the different types of damage in these conditions. Presentations on modelling of the materials performance with  links between the microstructure and the  processing parameters are welcome. Fundamental phenomena related to the topics as well as the description of new approaches or methodologies will be discussed among researchers of this symposium.

4. Thermomechanical processing, texture & recrystallization 

P. Lhuissier, R. Logé, C. Maurice

This symposium will explore all aspects of thermomechanical processing of aluminium alloys.  Microstructure control (texture, grain structure, precipitation...), thermomechanical field heterogeneities (stress, strain, strain rate, temperature...) or defects evolution (pores, intermetallics, segregations...) linked to thermomechanical processing are in the scope of this symposium.

Examples of potential topics include (but are not restricted to) :
- Pore and crack closure or healing, second phases alignment, particle breakdown
- Recrystallization, precipitation, and the coupling or competition between the two phenomena
- Microstructure / texture gradients, architectured microstructures
- Strain localization and damage
- Numerical simulation at the process or at the microstructure scale, multiscale approaches

The symposium will cover both academic research and R&D approaches.

5. Casting & solidification, recycling, fundamentals of additive manufacturing 

H. Combeau, P. Jarry, N. Limodin, A. Pichat, G. Salloum-Abou-Jaoude

This symposium will put the emphasis on the physical metallurgy of solidification considered as the first step of the aluminium alloys processing route, in terms of nucleation and growth, possibly in relation with the melt structure, and microstructure selection mechanisms. The symposium will also welcome communications on casting processes; on the various scales of mechanisms at work from fluid flow to diffusion and on the influence of actuators on the generation and design of solidification macro- and micro-structures as well as defect generation, possibly with perspectives on casting heredity in terms of properties or behaviour laws in the transformation schedule, in order to relate with the other symposia of the conference.  Experimental as well as modelling works are welcome, preferably in combination.

This symposium will also welcome communications on additive manufacturing of aluminium alloys insofar as they deal with solidification mechanisms. 

Finally the symposium aims at providing perspectives on the sea change in scrap flow expected in the future, on how alloy eco-design should and will affect melt quality and composition, on how melt purification needs, melt treatment processes, casting processes, monitoring thereof and downstream processing should evolve to take up this challenge, with the help of what renewed scientific approaches, R&D programs and collaborations.

6 : New directions in alloy and process development (I): additive manufacturing

M. Brochu, C. Desrayaux, G. Martin

This symposium provides an international forum to explore new research directions in the field of additive manufacturing of aluminum alloys. It covers all aspects of additive manufacturing: from raw materials (powders, wires) to final performances with a particular emphasis on alloy design dedicated to AM and processability by AM-routes. Both modeling and experimental approaches are considered. AM-processes including Laser Beam Melting, Electron Beam Melting, Direct Metal Deposition, Binder Jetting (MBJ), WAAM, etc are considered. Detailed investigations linking processing to microstructures to structural (mechanical) and/or functional (physical) properties are welcome. Approaches consisting in tailoring microstructures through AM-processing routes are also welcome. Post-treatments aiming at improving performances, and decreasing the residual stresses, of components produced through AM: HIP, heat treatments, surface treatments… are also included in the scope of this symposium.

7: New directions in alloy and process development (II): joining, severe plastic deformation, emerging processes 

M.N. Avettand-Fenoël, X. Sauvage, A. Simar

This symposium will provide an international forum to discuss about recent advances in joining of aluminum alloys in liquid or solid state. Both modeling and experimental approaches will be considered. It will cover all processes including brazing, laser welding, electron beam welding, arc welding, friction stir welding, linear friction welding, magnetic pulse welding, accumulative roll bonding, mechanical bonding, welding of dissimilar materials, hybrid processes, etc. This symposium will be also devoted to the potentiality of severe plastic deformation processes for the design of ultrafine grained microstructures in complex alloys to achieve high strength or superplastic properties. It will cover all processes, including high pressure torsion, equal channel angular pressing, cold drawing, accumulative swaging, multidirectional forging, high pressure sliding, or accumulative roll bonding,… Presentations about other emerging and innovative processes are also welcome, such as ageforming, magnetic pulse forming, hydroforming, shot peening, ultrasonic treatments...

8. Advanced characterization

S. Cazottes, J. Chevy, F. De Geuser, J. Douin, L. Salvo

This symposium welcomes contributions using or describing advanced characterization methods applied to aluminium alloys or more generally materials involved in aluminium alloy processing.

It will be an opportunity to showcase new technical or methodological developments from sample preparation to data interpretation. Fields like image/data analysis and modeling may also be covered to include the new possibilities offered by always more powerful computer assisted methods.

Industrial in-line characterization approaches aiming at relating microstructural information to industrial processing parameters are also in the scope.

All techniques are welcome and contributions dealing with in situ and/or operando analysis will be particularly appreciated.
