Structural Materials 1: (Metals and Minerals)

Course aim

To provide the student with:

• An appreciation of the technological context of materials engineering (making) and materials application (use)
• An appreciation of the principles of materials selection (i.e. intelligent use)
• An appreciation of the extraction, concentration and processing of minerals
• An appreciation of the link between product design, manufacturing (processing) and materials properties

Course content

Irons and Steels

• Irons & steels: classification according to carbon content
• Plain carbon steels (<2% C)
  - Crystallography
  - Phase diagrams transitions and non equilibrium structures
  - Thermal processing and solubility of C in different Fe phases
• Steels for power transmission (gears camshafts etc)
  - Diffusion treatments (C, N, based)
  - Surface (mm thick) modification

Cast Irons (>2% C)

• White, gray and "other" irons
• Nano-structured steels (bainite)
• Extreme Fe materials
  - Damascus and ancient Japanese blades
  - High tensile steel wires

Non-ferrous metals

• Look at historic uses, i.e. products manufactured from non-ferrous metals
• Properties of non ferrous metals explored through the Materials selection for the skin of aircraft - Comet (1950s) to Concorde
  - Lightness
  - Specific strength and modulus
  - Work and solution hardening
  - Age hardening or precipitation hardening (alloying)
  - Composites
  - High performance alloys primarily Al and Ti
• Failure studies
  - Modes of failure
  - Brittle and ductile failures modes
  -Griffiths cracks
  - Fatigue
  - Pitting Corrosion
• Copper, Tim and other 'base' metals

Minerals

• The processes used to manipulate the particule size of solid raw materials and to separate valuable materials from materials of no value
• Particle size reduction
• Separation processes
  - Density
  - Electrical properties
  - Magnetic properties
  - Surface properties
• Solid-liquid separation
