P4 The processing of materials has an effect on the materials’ properties and behaviour. You are to prepare a report that outlines the different processes that materials undergo and the effect that they have on the materials’ properties and behaviour.

The materials you are to report on include:
•
• Processing of ceramic (terracotta)
• Processing of composites (fibre and particle) Effect on post-production smart materials (piezoelectric material in airbags)

Steel (metal Processing)
Steel is an alloy of cast iron and other metallic elements, normally carbon and others that can then be processed in a few different ways such as cold and hot working.
Steel scraps and molten iron are added together with high purity oxygen, in order to create Molten Steel. Forming and finishing processes are important to determine some of the steels properties. Coating is a process than can be used in order to aid in corrosion resistance. Tempering is used to add hardness and create other surface textures and finishes. Heat treating is a series of processes in metalworking used to alter the physical properties of the metal involved and can consist of any or all of the following: annealing, case hardening, precipitation …show more content…
There is also extrusion blow molding, used for thermoplastics such as polytheylene and PVC. Thermoforming can be used for most types of plastic.
Blow molding is done by melting the plastic, forming it around a mold or parison which
A sphere of glass, air is then blown in at high pressure in order to push the plastic out of the mold, then hardening as it cools after which the part is removed from the machine.
