Phase transformation in nanocrystalline intermetallic alloys

Project Details


The central objective of this cooperative research programme is to compare the properties and behaviour of intermetallic alloy phases, made disordered either by mechanical attrition, which generates nanocrystalline structures, or by purely thermal treatment (rapid quenching from high temperatures). The kinetics and mechanisms of thermal reordering of such metastable disordered microstructures, made by the two alternative methods, will be examined in detail. This central objective will be pursued with respect both to a) L1"sub2" alloy phases based on the face-centred cubic, and to b) B2 alloy phases based on the body-centred cubic structure. Both the disordered phases and the reordered phases are to be fully characterised by using a battery of physical techniques.
