Projects Available

Metal matrix composites produced by semi-solid processing
K. O'Reilly / M. Galano / F. Audebert

The aim of this project is to use semisolid processing to obtain novel graded properties and selective local reinforcement of Al alloy components. The processing is based on the rapid induction heating into the semi-solid state of cylindrical slugs of materials containing various fine-scale complex microstructures. Stacking of slugs of various compositions will be used to obtain the gradation in properties or local reinforcement. Semi-solid material will subsequently be injected into an Ube 350 tonne New Rheocaster to produce components. Semi-solid techniques are known to produce small, equiaxed, non-dendritic grains resulting in an increase in the toughness of the material.Materials manufactured by this route will be suitable for use at a wide range of temperatures, dependent on the the Al alloy system. The applications the project will be focusing on are engine blocks and automotive and machine components.Different types of nano-sized reinforcements will be used in order to optimise the properties achieved in the final components. The fine scale complex microstructures of the composites obtained will need to be characterised at the different stages of the processing to gain an understanding of the processing/microstructure relationship and the microstructural evolution, to provide a platform to control the complex microstructures and to understand mechanical behaviour.

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.

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.
