Current Projects

Research at LMM

The LMM addresses the science and engineering of structural metallic materials, with particular focus on advanced metallic materials, including metal matrix composites and metal foams.

Research at the LMM spans the spectrum from materials processing to the exploration of links between the microstructure and the properties of advanced metallic materials, for both structural and functional applications. We explore several topics in materials science, including capillarity, infiltration processing, microstructural development, micromechanics, deformation, fracture and physical properties.

Probing at the nanoscale the structure and properties of hard second phases in alloys and composites

Lionel Michelet, Marta Fornabaio and Andreas Mortensen with former contributions from Vaclav Pejcal, Martin Mueller, Goran Zagar, Andreas Rossoll, Cyril Dénéréaz, Raphael Charvet 

Our ambition in this new project funded by an ERC Advanced Grant is to probe the strength of “second” phases in multiphase metal alloys and composites, meaning of hard particles added to strengthen a metal, or alternatively of brittle inclusions that weaken it. Such phases are ubiquitous in structural metals; yet not much is known of the                                                                   microstructural features that govern their strength.

Capillarity in infiltration

G. Schneider, L. Weber, and A. Mortensen, with earlier contributions from A. Léger, N. Rojo Calderon, M. Bharaini, C. Bacciarini, R. Charvet and W. Dufour.

In this project funded by the Swiss National Science Foundation we explore the physics of capillarity in pressure infiltration by conducting high-precision experiments under conditions of low capillary number.

Aluminium microfibres

Suzanne Verheyden, Léa Deillon and A. Mortensen (with former contributions from Jérôme Krebs and Csilla Miko)

This project funded by the Swiss National Science Foundation aims for the development of processes enabling the net-shape casting of metallic samples on the scale of one to one hundred micrometres, and their use towards the exploration of the plasticity size effect in metals and alloys.

 

Interface thermal conductance between metal and dielectrics

This new research activity aims at understanding the basic heat transfer mechanisms at sound chemically bonded interfaces between metals and dielectrics and finding ways to improve the heat transfer at these interfaces.
