Summary on Grant Application Form
The World Technology Evaluation Centre has just carried out a survey of world-wide capability in the field of nanotechnology and nanomaterials. Our group at the Oxford Centre for Advanced Materials and Composites (OCAMAC) was identified as one of the world leaders. The objective of this project is to use the specialist high resolution microanalytical techniques available within OCAMAC to investigate experimentally the role of the different elements necessary for the formation of amorphous and nanocrystalline microstructures. A series of alloys has been chosen from three classes of amorphous and nanocrystalline materials being developed for different industrial applications: high strength A1-based alloys; structural Zr-based bulk glass forming alloys; and Fe-based magnetic alloys. In order to address the common aspects of kinetic control of these metastable microstructures, the chosen alloys exhibit a variety of different decomposition routes including primary crystallization to form elemental solid solutions, intermetallics or quasicrystals or alternatively spinodal decomposition. Measurements are expected to quantify such parameters such as the number density of nucleii, the increase in solute in the nanocrystals, the local partitioning coefficients and the diffusion coefficients of the slow diffusing species.
