The national network « metallurgy »

By François Mudry
Président de l’IRT-M2P, 4 rue Augustin Fresnel, 57070 Metz

François Mudry

The Academy of the sciences and the Academy of the technologies published in 2010 a report on the metallurgy in France. A committee was set up by the Ministry of Education and Research with the aim to study the implementation of the various recommendations. The committee made a series of concrete propositions at the beginning of 2014, concerning a structuralization of the metallurgy in France with various aspects: needs and organization of training, of research, of the relations with industry and the visibility of the discipline. This short article quickly presents these issues.

The summer schools on physical metallurgy (1966 – 2012)

By Jean Philibert
Jean Philibert

Events inspired by the experience of summer schools on physical metallurgy should provide young researchers with a real and essential therapy. Generations change, science and its methods change, but the need for solid fundamental courses, supplemented by exercises and practical work, remains a necessity: they were and should remain the heart of these schools, in a relaxing environment which is essential for promoting contacts and exchanges.

L’acier fondu au creuset en France au 19e siècle : héritage de l’Orient et naissance des aciers spéciaux

by J. Le Coze
J. Le Coze

Which are the similarities and the differences between the tools and techniques used for crucible steel melting, in Near and Middle East, India and China, as compared with those which appeared in Europe at the end of the 18th century?

Which were the crucibles, the melted products, the different types of furnaces, the process control, the strategic importance of these steels in the 19th century, in spite of a low level production? In order to know more about a historical subject, not largely treated subject concerning the steel-making history and technics, and to place correctly the ancestral techniques that gave birth to the steel industry of special steels, see the articles of J. Le Coze: Crucible steel in France in the 19th century: heritage from Orient and rise of special steels

The promises of the graphene - Remarkable properties and applications

by Johann Coraux et Mark Oliver Goerbig
Stocklib © - Graphene consists of carbon atoms arranged into a honeycomb structure.

The graphene is one of the most promising materials for a technology of the future. It can be distinguished among the other materials by its remarkable electronic properties accompanied at the same time with a big mechanical flexibility, with a big robustness, and with a big chemical stability. Today, the graphene leaves the fundamental research laboratories and makes its road towards the industry because of its big potential for various applications. This is made possible, in particular, by a big progress in the industrial production of graphène on a large scale.

Thoughts about materials sciences

by Alain Thorel

The elements that constitute our materials of every day result from the stars. Materials are everywhere in our life, at such a point such as the user has only little consciousness of the degree of sophistication of the studies and the knowledge necessary to produce the object that he has in hands. The science of materials is a living, rapidly growing science, which overflows on numerous disciplines, interfaces with them. The way the research - including that in science of materials - is organized and financed, and the way it is perceived, make difficult the work of the researcher which has an eminent role to play, because it helps to give form to the future, the long term, in a world with an uncertain environment; his freedom guarantees our future!

Modeling the degradation of Portland cement pastes by biogenic organic acids

by Laurent De Windt and Philippe Devillers

A bioleaching test of OPC pastes by the fungus Aspergillus niger is modeled with the reactive transport code HYTEC. Modeling indicates that the biogenic organic acids (mostly carboxylic acids) strongly accelerate hydrate dissolution by acidic hydrolysis while their complexations of aluminum have an effect on the secondary gel stability only. Degradation depth could be affected by precipitation of calcium salts. Precipitation of calcium oxalate is predicted by modeling but was hindered in the present experiment.

Promoting the metrology within a national network

by Nicolas Feltin, Khalifa Aguir, Sébastien Ducourtieux, Benoît Poyet, Pierre Gournay and Yannick De Wilde
French metrology AFM

The Laboratoire National d'Essais (LNE), leader of the French metrology, and the Centre of Competences in Nanosciences "C’Nano", actor of research, create the Nanometrology club.

The day of launch was October 6th, 2011 within the framework of the exhibition MesureExpoVision (Paris). This Club has for vocation to gather researchers, industrialists and governmental agencies, around the problems of metrology concerning the development of the nanosciences and the nanotechnologies.

Application of high resolution thermal drift free nanoindentation system for characterization of gels and spherical indenters

by Jiri Nohava, Guillaume Berthout
Detail of the UNHT measurement head. The indenter is located on the left hand side; ball reference is on the right hand side.

With the development of ultra sensitive nanoindentation systems, the problem of sphericity of a ball indenter and of thermal drift becomes a significant issue. We describe the main features of the CSM Instruments Ultra Nanoindentation Tester, focusing on characterization of spherical indenter in relation to creep studies on Polymethyl-methacrylate (PMMA). The indentation and creep data obtained from this system can be used directly without any software or hardware correction. The system also proved itself to be a powerful method for the measurement of extremely soft gels with properties similar to biological tissues.
