Projects Available

Development of aluminium matrix nanocomposites for high temperature applications
M Galano / F. Audebert

This project  is based on the development of Aluminium Matrix Complex Nanocomposties (AlMCNCs) with combinations of reinforcement strategies at the nanoscale that offer unique properties to target specific applications with an enhancement of combined properties i.e. increase thermal stability, ductility at forging temperature, and higher strength and Young’s modulus in higher performance applications. New materials will be used as nanoreinforcements for improving Young’s modulus and strength of nanoquasicrystalline alloys (NQX). Small Al-particles will be used as a plasticizer for improving the ductility of NQX alloys at forging temperature. These combinations of reinforcement strategies at the nanoscale will create unique complex nanocomposites with a unique combination of properties. Thus, a detailed study on the processing and the mechanisms responsible for microstructural stability and mechanical properties is required to develop these new Al matrix complex nanocomposites and to provide a platform for a disruptive knowledge for designing the right material for each application. Several aspects will be developed within the project: (i)Investigation the different processing routes that lead to obtaining AlMCNCs in bulk shape for industrial applications. (ii)Development of bulk AlMCNCs with different combinations of exciting mechanical properties for producing high industrial impact. (iii)Testing of the new AlMCNCs in real applicationsThe project makes use of processing, microstructural characterisation facilities and expertise and draws on the latest alloy developments within the research group that offer genuine prospects for industrially useful nanomaterials. This project will be within an already running EPSRC/RAEng project that is working on the development of bulk nanostructured alloy alloys and will run with the collaboration of several industrial partners representing a range of interests to pull through developed know-how.

(ii)    Development of bulk Metal-Metal Matrix Complex composites with different combinations of exciting mechanical properties for producing high industrial impact.
(iii)    Modelling of the strengthening and deformation mechanisms at the nanoscale in order to predict the mechanical properties of the different composites types.
The project makes use of processing, microstructural characterisation facilities and expertise and draws on the latest alloy developments within the research group that offer genuine prospects for industrially useful nanomaterials. Strong industrial support is already in place for different aspects of the project in particular a company specializing in processing simulations will be carrying out the modelling for the different nanocomposites developed.

Manufacturing and characterization of new light weight alloys
M. Galano/ F. Audebert

The design of new light weight materials (Al and Mg based) is of extreme importance to industry due to the constant need to develop materials that combine high strength and light weight. This project is based on the development of new alloys systems by means of diverse rapid solidification techniques achieving cooling rates of 10 6 K/s. These rapid solidification techniques allow obtaining microstructures that combine several stable and metastable phases such as amorphous, quasicrystalline and crystalline phases opening wide range of alternative phases to be able to produce innovative light weight alloys for demanding applications. Materials are going to be characterised by X- Ray analysis, calorimetry and electron microscopy techniques. The evolution of the microstructure is going to be studied by means of heat treatments, structural characterisation and mechanical testing in order to understand the phase transformations and the potential properties for structural applications.

Mechanisms for the control of fatigue resistance of advanced lightweight nano-composites
James Marrow, Marina Galano, Fernando Audebert

This project is concerned with the role of microstructure in the fatigue resistance of novel high strength Light weight nanostructured alloys. A new family of rapid solidified alloys show good mechanical properties with combined high strength and low density, these alloys have the potential to be used in pistons in car engines and replace Ti-alloys in gas turbines; the consequent reduction in weight and inertial forces will reduce fuel consumption and increase power output.

Tests performed to data show these alloys have very good fatigue resistance, but there have been no fundamental studies to investigate the mechanisms for this; the hypothesis is that initiated fatigue cracks are arrested at interfaces between the matrix and reinforced zones.  If so, then the strain paths arising from process variations during forging may have a significant effect on microstructure and the local fatigue properties.  To study this, a range of microstructures of a nanostructured Al alloy obtained by different heat treatments and processing conditions  will be produced and tested to correlate fatigue crack initiation and growth with the microstructure; importantly the interactions between arrested fatigue cracks and local microstructure will be studied using advanced electron microscopy, including high resolution EBSD and TEM of FIB-milled selected regions, to develop mechanistic models for fatigue resistance.  The interactions between microstructure and crack propagation may also be studied by in situ high-resolution computed tomography (Marrow, T.J. et al (2014) http://dx.doi.org/10.1016/j.ijfatigue.2014.04.003).

The project is suitable for students with an engineering, physics or materials background and will involve techniques such as electron microscopy, materials processing digital image correlation, finite element modelling and computed X-ray tomography.
