Brass, Bronze and Steel are alloys. To break down a design problem or product into manageable parts and learn from them. A process where metals are heated to a specific temperature and then allowed to cool slowly. The process allows molecules within the metal to realign making the material more soft and ductile; this makes it easier to shape and machine. A process of adding detailed comments to design solutions. Normally in the form of written notes. A process where an electrical charge and specific chemicals are used to oxidise the surface of a metal, then dyed a different colour. The oxidised surface makes the material slightly harder (surface hardness only) and more resistant to corrosion. The study of the measurements of the human body. A machine or product. Where component parts are joined together to make products, or sub-assemblies. A diagram, technical drawing or picture of a product, that clearly shows how all separate parts assemble together. It should also help to demonstrate assembly order. 6 Copyright 2009 AQA and its licensors. All rights reserved. klm
