Characterisation of mechanical and thermal hot properties
Description: The thermophysical properties of
pure metals or alloys have been widely studied by the metallurgy industries,
giving them the data needed for the simulation, but also for a better scientific
understanding of different physical process. Today, the simulations of material
forming process are powerful and irreplaceable tools for the design and the
modelling of new pieces, for the automotive industry, for example. So, there is
a constant need of thermophysical data more and more accurate on known material
as well as data on new alloys. The laboratory of the sector MMS is specially
equipped to study phase transformation and measuring thermophysical properties
(a, l, Cp…) and studying microstructure of
materials. ATD – DSC – TG (

Effect of carbides and inclusions in high alloyed irons and steels
Description: The goal of this project is to
define the relationship between micro and macroscopic material properties that
can be used in the simulations of the rupture mechanisms. A rigorous set of
experiences must be planned and quantitative micro- as well as macroscopic
techniques is required.
This
project is interested in steels and high alloyed cast irons and is focused on
the quantitative and statistical relationship between, on one side, the
inclusions property, the amount of carbides and the microstructure and, on the
other side, on the mechanical properties. This research is based on the
methodology experimented in a previous project. This previous research was
built on the development of experimental micro- and macroscopic techniques.
One of
the main points is the size of the carbides and the inclusions, which makes it
tough to detect them by classical microscopic imagery. So, other methods have
to be developed.
In this
project, the focus has been made on the diversity of the materials examined
above the number of experiment made on each.

Development of new alloys for hot rolls
Description: .The hot rolling mill is a massive
piece that endures high service solicitation like thermal and mechanical
constraints as well as fatigue or usury. The rolled product quality and the
productivity of the process are directly related to the quality of the working
mills.
The
goal of this project is to enhance the knowledge in this sector and
particularly to study the kinetic of the precipitation and the formation of the
carbides required for a good quality of the product. Additional studies on
surface corrosion will be done at the
This
approach is essential to define the optimal structure leading to the highest
life span of the mills.

§
Thixomoulding
Description: Semi-solid metals
exhibit time and strain rate dependent behavior known as thixotropy: they
behave like solids in the undisturbed state and like liquids during shearing
provided the shear rate is high enough. The solid-like behavior is due to the
presence of a solid skeleton consisting of interconnected grains. Shearing
breaks the bonds between grains leading to a release of entrapped liquid and
decreasing the viscosity of the semi-solid alloy. Semi-solid metal forming
called thixoforming exploits this thixotropic and shear-thinning behavior since
the semi-solid slug may be handeable but also may flow easily in the die. The
use of FE simulations to obtain the filling of the dies and to optimize the
thixoforming process is clearly of a great interest.
The aim of this project is to write a new micro-macro
constitutive equation that describes the semi-solid behavior. This will be made
in two fronts: The first one is to plan a set of experiments in order to
determine the parameters of this law for steels; the second one is to implement
the new material law in the METAFOR FE code.

Development of Ti-LBC for turboreactors TITAERO
Description: The main goal of this project is
to develop a new material based on an existing alloy: Ti-LCB, but with better
fatigue damaging properties and sufficient ductility.
First,
the characterisation and the understanding of the relationships between the
thermo mechanical history and the fatigue structural properties will be
established. So, on one side, the construction of the microstructure along the
thermo mechanical path, implying allotropic transformation or phenomena like
rehabilitation, recrystallisation and grain growth, will be studied. On the
other side, the microscopic mechanisms leading to the structural properties of
this alloy, like tenacity, fatigue resistance and cyclic plasticity will be
examined.
Another
objective is to implement this knowledge into micro mechanical models. The
project will focus on a physical based model able to predict the fatigue
resistance of biphasic-Ti-alloys with thin grains.
The
third goal is the validation of the model based on real loading studies.

Fabrication of metallic foils by vacuum deposition – First Spin Off
Description: Metallic foils have proved to be
useful in many fields like packaging or magnetic products. So far, the foils
have been mainly produced by rolling in the case of soft materials like aluminium,
or by electrolysis in the case of metals like copper. Those process do not give
the surface quality required, so the foils must be treated by PVD (Physical
Vapour Deposition) afterwards.
In this
project, a technique of SIP (Self-induced Ion Plating) is proposed. This
technique would be able to realise foils with good surface quality in one step.
The SIP process is a combination of cathodic pulverisation process and
evaporation. Its main advantage is the high deposition rate and the good quality
of the deposit.
In the
actual state of the research, the goal is not yet to realise composite
materials, but to look at the possibilities to achieve thin coatings of the
materials that the composite will be made of.

§
Micro-macro study of high temperature damage in steels
Description: This project attempts to set a
micro-macro model of the hot damaging behaviour. Most of damaging models established
so far are ductile cold rupture, fragile rupture, fatigue or creep. All are
valid at low temperatures.
For
monotone solicitations at very high temperatures, the damage process is fast
creep or diffusion creep. The present project is focused on this particular
phenomenon.
The
industrial application is the simulation of the continuous casting and
particularly the areas where cracking can start.
The
final goal of this research is the definition of rupture criteria coupled with
a macroscopic damaging model. Those criteria should be able to predict the
cracking for any kind of solicitation and the origins of the cracking will be
analysable.

Virtual Intelligent Forging - Coordinated Action
Description: Forging and related metal forming
processes are key industrial technologies since they are required to produce
economically many highly reliable parts. Over the last decades, these
industrial processes have been improved through many RTD projects in materials
science, mechanical engineering and more recently in numerical simulation. The
goal of ViF-CA is to gather and analyse this scattered knowledge in order to
solve some of today's industrial problems and to incorporate into industrial
practices the recent advances in virtual production, supply chain and
life-cycle management. The strategy is to create a forging knowledge community
through several scientific, technological, training and educational activities.
The
consortium gathers educational and research organisations, experts in the
various scientific areas, and a large number of forging, software and IT
industries from 17 European countries. The Deliverables include a Book of
forging, projects for an e-Database and an e-learning platform, benchmarks for
process simulations and materials testing, and a structure for a virtual supply
chain.

Non-contact Ultrasonic sytem for rail track inspection (U-RAIL)
Description: Periodic in-track rail inspections are
performed to detect critical defects before they grow enough to cause
structural failure. Nondestructive inspection (NDI) technologies currently used
worldwide rely mainly on conventional ultrasonic technologies. These use water
filled rubber wheels, containing transmitter-receiver piezoelectric
transducers, that are kept in continuous contact to the rail running surface.
These methods have limitations, as they require contact conditions between the
inspection probes and the surface of the rail track. Although such contact
ultrasonic methodologies have been extensively and successfully used in
detecting many surface-breaking and internal cracks, and are proved to be
reliable, they are not perfect. In fact, train derailments caused by broken
rails that pass inspection still occur.
In an
effort to improve rail track inspections, this project proposes a non-contact
ultrasonic system for periodic in-field inspections of rail tracks that has
recognized advantages over conventional technologies currently available to the
railroad industry. The feasibility study, the development and the manufacture
of a prototype will prove the capability of the proposed inspection technique
for in-track rail flaw detection..

established in collaboration with the federal
The
objective of the BNEN project is to provide commonly accepted evaluation
methodologies especially adapted for the assessment of education programmes;
also the conclusions of an external evaluation of the BNEN scheme by EU-25
stakeholders in combination with a self assessment of the scheme, both based on
the afore-mentioned evaluation methodologies. Another goal is to obtain
recommendations and suggestions how the BNEN scheme and experience can be used
for the creation of the common "European Nuclear Education
Programme", and in extension how the scheme can be useful for the set-up
of European education programmes in general. Finally, it should get points of
particular interest that are of importance to stakeholders of the new member
countries and to women, and that therefore need to be integrated into the
common "European Nuclear Education Programme".
At
the end the BNEN project will have contributed to the mobility of the European
scientists and the creation of the European Area of Higher Education, to the
integration of the candidate countries into the European Research Area and thus
to the enlargement of Europe and also to the reinforcement of the place and
role of women in science.
