New developments of advanced high-strength steels for automotive applications
Publication date: Available online 28 November 2018Source: Comptes Rendus PhysiqueAuthor(s): Jean-Hubert Schmitt, Thierry IungAbstractAutomotive industry asks for higher resistant steels to lighten parts and improve crash resistance. Keeping a good ductility while increasing tensile strength requires the development of new grades in which hardening mechanisms counteract the drop in elongation when enhancing mechanical resistance. This is mainly achieved with multiphase steels and completing dislocation hardening by twinning and martensite transformation during straining. This has led to high-strength steel families, some o...

Re-interpretation of the Old Masters' practices through optical and rheological investigation: The presence of calcite
Publication date: Available online 22 November 2018Source: Comptes Rendus PhysiqueAuthor(s): Laurence de Viguerie, Helen Glanville, Guylaine Ducouret, Pierre Jacquemot, Phuong Anh Dang, Philippe WalterAbstractLead white, composed of a mixture of cerussite and hydrocerussite (respectively PbCO3 and Pb3(CO3)2(OH)2), is often associated in paintings with other white pigments, especially calcite. By combining in-situ analyses with paint reconstructions, we attempt to get a better understanding of the role of this addition of calcite and to investigate how artists may have used it to modify the properties of their paints. Lead-...

Apports de la colorimétrie et de la spectroradiométrie à la caractérisation in situ des peintures paléolithiques de la grotte Chauvet (Ardèche, France)
This article shows the methodology used, and it takes stock of the experience acquired in the research programme on the Chauvet Cave. It also attempts to show the benefits of taking spectroradiometric measurements on prehistoric artworks. However, the in-situ study of their colour cannot be a substitute for chemical and mineralogical analyses and the characterization of the materials, either sampled or in place. Its interest lies in its capacity for detecting even minimal changes in condition and composition. So our objective has been to establish comparisons between the graphic entities to identify the origins of the vari...

Recent advances in the metallurgy of aluminum alloys. Part II: Age hardening
Publication date: Available online 9 November 2018Source: Comptes Rendus PhysiqueAuthor(s): Christophe Sigli, Frédéric De Geuser, Alexis Deschamps, Joël Lépinoux, Michel PerezAbstractIn this paper are reviewed some recent progress on the understanding and simulation of aluminum alloy age hardening. The main phenomena governing the formation of precipitate microstructures in aluminum alloys are presented; they provide a qualitative understanding of the relationship between alloy chemistry, processing and final precipitate microstructure at the nanoscale. In a second part, we describe how modeling approaches are capable ...

Quantum simulation of the Hubbard model with ultracold fermions in optical lattices
Publication date: Available online 8 November 2018Source: Comptes Rendus PhysiqueAuthor(s): Leticia Tarruell, Laurent Sanchez-PalenciaAbstractUltracold atomic gases provide a fantastic platform to implement quantum simulators and investigate a variety of models initially introduced in condensed matter physics or other areas. One of the most promising applications of quantum simulation is the study of strongly correlated Fermi gases, for which exact theoretical results are not always possible with state-of-the-art approaches. Here, we review recent progress of the quantum simulation of the emblematic Fermi–Hubbard model w...
