Mathieu Brochu

The research projects conducted by Dr. Brochu target the process-microstructure-property relationship applied to processing and joining of bulk nanomaterials. In particular the following areas are currently under investigation:

• Fabrication of nanostructured powders using cryogenic processes
• Optimisation of advanced consolidation processes for the manufacturing of bulk nanostructured materials
• Engineering nanostructured feedstock for high temperature coatings and their oxide selectivity response
• Development of hi-frequency pulse welding processes for welding and freeforming of amorphous and bulk nanostructured materials
• Advanced joining processes applied to advanced materials and systems

In particular, the following projects are on going:
