Summary
The aim of this report is to investigate the materials and manufacturing processes involved in the making of specific components found in a Rover K series engine. The analysis consisted of two engine strip sessions where we were able to see the components first hand by doing this we were able to apply our limited existing knowledge of materials to begin to understand the choices made in designing the engine components. Moreover, additional research has helped us to understand the material selection in a greater detail; we found out that all the components are alloys of some kind to help better the properties for the specific application within the engine.

Aluminium Alloy (Karim Habbas)
The cylinder head of the K series has been casted from a cast alloy 319.0. The composition is as follows:

The alloy is strengthened by the precipitation of hardening Mg and Cu rich phases, during ageing heat treatment. As a result the material can be up to 30% stronger, when the copper crystals are kept small forcing them to conform to the structure of the aluminium. Silicon is an influential element in the composition because of its high fluidity which allows the alloy to flow evenly in all corners of a casting mould as well as limiting thermal expansion reducing the rate of shrinkage in the casting process. Casting is most...
