In-Situ copper MMCs
C. Krüger, A. Mortensen
This project funded by a CTI/industry collaborative grant is an exploration of industrially applicable routes for the production of copper-based composites containing a high fraction of light reinforcement particles, of density lower than that of copper together with attractive mechanical properties. Two routes are explored: infiltration and a new in-situ process.
L.Weber , R. Tavangar
This research activity is motivated by the need for highly efficient heat sink materials having a tailored coefficient of thermal expansion and a high thermal conductivity. To this end we investigate the parameters that allow successfully manufacturing of metals containing large volume fractions of diamond particles.
E. Klay, F. Diologent, A. Mortensen
The aim of this project is to determine the transition temperature of different alloys Au y Cu 1-x-y X x (with x ranging from 0 to 15% and y from 75 to 78 % wt. %) and identified the phases present below the order-disorder temperature. Subsequently the mechanical response of the different alloys according to their microstructures and chemistries will be characterized.
Fracture toughness of TiAl
N. Barbi, R. Goodall, F. Diologent, A. Mortensen
This project is part of the Europe-wide IMPRESS program, examining aspects of the use of TiAl-based alloys. These intermetallic alloys have several desirable properties, including high strength at elevated temperatures, and the work carried out here aims to assess the fracture behaviour of these materials up to 650°C.
D. Empl, V. Laporte, L. Felberbaum and A. Mortensen
To improve our understanding of cracking phenomena observed in the deformation processing of Cu-Ni-Sn alloys that may contain further alloy elements, in particular lead.
Particle reinforced aluminium
This was an extensive investigation of the processing, structure and mechanical behaviour of open-celled aluminium-based foams sponsored by the Swiss National Science Foundation.
Capillarity in infiltration
M. Kida, M. Bahraini, L. Weber, A. Mortensen
A study of capillary phenomena in the infiltration processing of ceramic particle reinforced metal composites, and of the resulting materials.
Microstructural evolution of 6XXX aluminium alloys during deformation processing
P. Castany, F. Diologent, A. Mortensen
The goal of this project was to better understand the different precipitation sequences that exist in specific alloys of this family during thermomechanical processing, aiming to improve their mechanical response and understand mechanisms of failure during bending of sheet from such alloys.
Laminated composites (in collaboration with Tokyo University)
The goal of this project is to develop novel metal-based layered composites and explore new applications through fundamental studies of materials design and processing methods.
Mechanical properties of metallurgical products fabricated by additive manufacturing
Ana Fernandez, Ludger Weber and Andreas Mortensen
Our mission in the project is to undertake exploratory investigations in metallic components fabricated by different additive manufacturing processes. We explore the links between additive processing parameters, microstructural evolution and the final properties of these metallic AM parts.
Infiltrated ceramic particle reinforced metals
Gabriella Tarantino, Ludger Weber, Cyril Dénéréaz, Raphael Charvet, Willy Dufour and Andreas Mortensen
In this project funded by the US Army Research Office we explore the influence of hydrostatic pressure on the plastic deformation of infiltrated particle reinforced aluminium composites.
