Area of Research: Sintering Processing
Summary of Research: Key Words: conventional sintering
The Department of Metallurgy and Materials Engineering ( www.mtm.kuleuven.be ) is actively involved in several strategic fields of materials research and development. The department has a flexible structure of six research teams (about 160 employees) and a long tradition of strong interaction between the individuals and teams, which has allowed it to tackle scientific and industrial problems in a multidisciplinary way. MTM is currently active in the field of advanced alloys and production processes, ceramic and intermetallic materials and composites, polymer composites, thermodynamics, deformation processing and mechanical behaviour of metals, materials performance and degradation, non-destructive testing and surface engineering. This cross-fertilisation - involving scientific as well as technical and administrative staff - has substantially contributed to the high standards of research at MTM and hence to its recognition as a Centre of Excellence on a n! ational and on an international level. The department, being the largest of its kind in Belgium, has traditionally always maintained close links with the Belgian and European industry. Two of the MTM-research teams are actually involved in powder metallurgy. The first one is the research team on Advanced Alloys and Production Processes (A2P2) (http://www.mtm.kuleuven.ac.be/Research/A2P2/index.html), supervised by prof. L. Froyen and prof. J. van Humbeeck. The activities in this group are focussed on the development of new and improved material systems and advanced production routes such as Selective Laser Powder Processing (SLPP). The starting point is the physical metallurgy (microstructure formation, defects, .) and its relationship to material synthesis (production parameters and performance (properties). Attention is focussed on process optimisation of solidification processes, powder metallurgical techniques, plasma processing, etc. The major topics of interest are: · Solidification: multi-component alloys, metal matrix composites including in situ synthesis, porous metals
· Powder metallurgy: aluminium based alloys, reactive sintering, iron based alloys and soft magnetic powders, intermetallics, atomisation, mechanical alloying
· Biomaterials: scaffolds, surface coatings and drug delivery systems
· Shape memory alloys: stability, functional properties and new alloy systems
· Ultrafine grain size materials: stability and microstructural properties
· Interaction material-process during thermo-physical manufacturing: Electro-Discharge Machining (EDM), Selective Laser Sintering (SLS), Laser Beam Machining (LBM)
The second research team is the one on Composites and Ceramics (C2) (http://www.mtm.kuleuven.ac.be/Research/C2/Ceramics Research group.htm), co-ordinated by prof. J. Vleugels and prof. O. Van der Biest, with a particular expertise in the field of ceramics and cemented carbides. To be able to profit from the exceptional properties of these materials, one has to investigate ways of processing them in a cost-effective and quality-assuring way. This critical issue is a top-priority of the ceramic research group. The major topics of interest are:
Ø Processing of ceramic materials
· Powder synthesis
· Shaping
· Colloidal processing by means of Electrophoretic deposition (EPD)
· Porous materials
· Sintering : conventional, microwave, hot pressing, FAST(SPS)
Ø Functional properties of ceramic materials
· Basic mechanical properties
· Tribological properties
· Elastic and damping properties
· Fatigue
· Chemical compatibility of metals and ceramics
Ø Modelling of processing and behaviour of ceramic materials
· Damage accumulation under sintering
· Cyclic and creep deformation
· Electrophoretic deposition (EPD)
· Field Assisted Sintering Technology (FAST) or Spark Plasma Sintering (SPS)
