Metal-matrix composites (MMCs) have suffered from a couple of problems in motorsport. The first is that there have been restrictive regulations banning such materials, either explicitly or via a limit on specific modulus (the ratio of elastic modulus... read more

Magnesium as a piston material

The racing piston market is dominated by aluminium, as are the roadcar and motorcycle markets, although in general the alloys used in racing are quite different from those in passenger vehicles. As racing engineers we look for increased durability an... read more

On first inspection, steel seems like an unlikely material to use for a cylinder liners. Its density is almost three times that of aluminium, its thermal expansion coefficient is much lower than that of the aluminium piston that runs inside it, and i... read more

There are many applications for high-strength steels in the modern racing powertrain. Their use allows us to make lighter parts and, given that race engine and transmission designers spend much time, effort and money on reducing mass, it should come ... read more
