In this way ceramics are obtained in which the metallic oxides are very closely interwoven in the form of monocrystals, which gives them remarkable mechanicalproperties... A second thesis is in progress to evaluate the mechanicalproperties of these materials, particularly creep properties (deformations) and toughness (fragility in the presence of a defect)
This Nb3Si phase (which is not desired because of bad mechanicalproperties) can be transformed into Nb5Si3 (through the reaction 3 Nb3Si... The work programme includes definition of alloy compositions, extensive characterisation, and development of industrial scale processing, manufacturing and machining techniques to propose a new generation of materials exhibiting an acceptable trade-off between mechanicalproperties (at low and high temperature) and oxidation resistance
No mechanical movement. It's controlled by varying the properties of a rather special lens- made of plasma- a material state constituted of ions and electrons with very particular properties...
