Atomic Structure & Unit Cells and Phase Diagrams

To investigate transformations and resultant information of macro-structures on solidification using information on ferrous and non-ferrous metals and alloys.  You will:

1)  Explain how the relationship in the formation of atomic unit cells effects the formation of crystals and structure on solidification in sand and metals mounds.

2)  Evaluate and describe how various cooling rates produce a range of differing sized crystals and grains in castings and ingots.

3)  Summarise the key features of your learning in your conclusion.

Mechanical Properties of Metals and Introduction to Heat Treatment

To evaluate a range of mechanical properties and how these properties change after heat treatment using information on ferrous and non-ferrous metals and alloys.  You will:

1)  Define the following terms: Toughness, Brittleness and Ductility, providing examples of mechanical testing results for three metals or alloys.

2)  Re-produce tensile test diagrams for the 3 materials above, identifying and labelling the mechanical properties.

3)  Describe the heat treatment which can be undertaken to maximise their mechanical properties of the metals or alloys identified above.

4)  Summarise the key features of your learning in your conclusion.

Mechanical Deformation Processes and Casting Processes

To evaluate a range of mechanical properties and how these properties change after heat treatment.  You will:

1)  Select and describe one process route used in Wrought Mechanical Deformation, making reference to any metallurgical and mechanical properties (including grain flow, effects on non-metallic inclusions and mechanical failure.

2)  Select and describe one casting method process route, making reference to quality, chemical composition, testing, manufacturing and production costs, with lines to the metallurgical and mechanical properties of the resulting product.

3)  Summarise the key features of your learning promoting your learning outcomes and answers in your conclusion.
