Physical Metallurgy Laboratory (LaMeF)
1) Group history
The Physical Metallurgy group acts on the design of new alloys and on the
study of the correlation among metallurgical processing, phase transformation
and microstructure formation, residual stresses and crystallographic texture in
metals for structural applications. Currently, the group develops new light high
performance magnesium-based alloys with rare earth addition for aerospace
application and studies its friction stir weldability. Another recent work
comprises the research of innovative manganese-based austenitic steels
without nickel addition with TWIP and TRIP effects for the automotive industry
and its weldability by conventional arc welding technologies as well as friction
stir welding. These steels combine, in a unique manner, high mechanical
strength and good ductility with low processing costs. In partnership with
companies, new anti-wear ceramic coatings produced by physical vapor
deposition have been developed, as well as explosion cladding of nickel alloys
and stainless steels with structural low alloy steels.
