Research Interests (Lay Summary)
While most commercial metal matrix composites are aluminium-based, steel-based metal matrix composites can be used in a variety of applications. For example, stainless steel 316L reinforced by silicon carbide can offer corrosion resistance with increased stiffness as may be required in marine, fuel processing or vehicle fuel line, aerospace or food processing applications. Other applications could include armour plating and vehicle mechanisms, where higher stiffness and/or wear resistance are required compared to what can be achieved with aluminium matrix composites. It is worth noting that moving mechanical components with higher stiffness can provide an important efficiency of energy transfer and hence energy saving.
One of Andre’s focus areas involves integrating materials such as silicon carbide, tungsten carbide and carbon allotropes within the metal additive manufacturing process. He is exploring this by creating nano-particle liquid suspensions and evaluating routes for incorporation into metal matrix powders. Correlation of production parameters and resultant part properties will be examined for process optimisation. Nano-material characterisation techniques will be utilised to enable a better fundamental understanding of the effects of the reinforcement phase.
