High resolution microtomography of metal foams

The necessity for devising more effective heat transfer technologies and innovative materials, capable of increasing performances while keeping power consumption, size and cost at reasonable levels, is well recognized. Under this prospect, metal foams are good candidates for improving the thermal efficiency of heat transfer devices and allowing, at the same time, the use of smaller and lighter equipment.

Evaluation of laser shock peening process of surfaces for aeronautical structural applications

Evaluation of laser shock peening process parameters incorporating Almen strip deflections

Engineering of component surfaces using Laser Shock Peening (LSP) requires optimisation of key process parameters to enhance performance through the generation of beneficial compressive residual stresses. Quantification of residual stress fields typically requires considerable experimental resources involving multiple complementary techniques to obtain reliable measurements through the depth of the target material. LSP induced plastic strains lead to the formation of residual stresses and cause deformation of thin components.

Chemical characterization of composite materials

Caratterizzazione chimica di materiali compositi

The composite of Ti6Al4V alloy, reinforced by unidirectional SiC fibres coated with graphite and produced by roll diffusion bonding (RDB), is a promising material for aeronautical applications including turbine parts that operate at temperatures in the range 500–600 °C. For these components, the stability of mechanical properties is one of the most important requirements.
