Mechanical Metallurgy Laboratory (LMM)

Research at the Laboratory of Mechanical Metallurgy addresses the science and engineering of advanced metallic materials.

Our activities and interests span the entire spectrum from materials processing to the exploration of links between the microstructure and the properties of materials. Materials we study are made at least in part of metal and can be destined for structural or for functional applications.

Our approach is largely but not exclusively experimental and touches upon a number of subtopics of materials science. These include capillarity, infiltration, powder densification, phase transformations including solidification, composite and cellular materials, micromechanics, damage and fracture, dislocational plasticity and creep, and the physics of conduction.
