Plain bearings come in a huge range of sizes, and in dealing with engines we will be familiar with a number of different types. The simplest are the cylindrical bush types which we see in various guises, most notably as con rod bushes and valve guide... read more

Powder metallurgy steels

Steels make up a large part of a typical race engine: while most race engines have the main castings made of aluminium or cast iron, steel remains the favourite for a number of other components, notably camshafts and crankshafts. While cast iron can ... read more

Rapid prototyping

Until relatively recently, the so-called 'rapid prototype' manufacturing methods were restricted to polymers and some other fairly 'flaky' materials - at least in terms of commercial availability. After the initial polymer materials (some of which ar... read more

In terms of engine development leading materials development, modern gas turbines are an excellent example. Since the days of Sir Frank Whittle, these engines have been able to progress only through parallel development of materials that are capable ... read more

Titanium as a fastener material

Titanium is banned in the current Formula One engine regulations from being used for threaded fasteners, despite its attractive attributes for such components. The rules specify that threaded fasteners must be made from alloys based on one of three e... read more

High-strength aluminium

Despite not being fettered by overbearing regulation, the use of aluminium in the production engine remains popular because the material has much merit. While there are many production applications where lower-density materials such as magnesium or n... read more

Metal-matrix composites

There are a wide range of metals used in the modern race engine. Where regulations are sufficiently liberal, we may find an engine containing everything from aluminium, magnesium and steel to titanium and tungsten. In many ways the materials behave v... read more

Tungsten

The use of tungsten in motor racing is widespread, especially on the chassis side of the business, where its high density makes the material prized for use as chassis ballast. Commonly cars are designed and made underweight compared to the regulation... read more

Copper

The applications of copper alloys in engines are generally those where we might expect to see relative movement or where a combination of strength, wear resistance and thermal conductivity is required. A favourite type for many of these applications ... read more

Directional strength of steels

There is little doubt that, in many ways, steels have improved markedly in recent years. Fatigue properties in particular have seen a large improvement owing to better steel cleanliness. However, it is not only the cleanliness that affects fatigue be... read more
