Syllabus |
|
Introduction to engineering materials, microstructure, classifications and selection: Steels and non-ferrous alloys. Atomic structure (crystals and defects) and microstructure (grains and grain boundaries). Solidification and deformation. Structural ceramics. Polymers and polymer-composites Other materials (wood, concrete…) Mechanical testing and mechanical properties of metals: The tensile test. Engineering and true stress/strain; elastic and plasticdeformation; yielding; effect of strain-rate and temperature. Deformation. Microstructural factors (grain size) and strengthening (work hardening) in pure metals. Flow stress. Annealing and hot working (recovery, recrystallisation and grain growth). Hardness Testing. Vickers, Brinell and Rockwell. Fatigue Failure and Fatigue Testing. S-N curves; the Goodman diagram. Creep. Creep strength, effect of temperature and stress Impact fracture. Ductile and brittle behaviour. Charpy impact test. DBTT. Mechanical Properties of Ceramics Mechanical Properties of Polymers and polymer-composites Heat Treatment and Microstructure-Property Control Strengthening processes in metals. Cold work, grain size, solution hardening, precipitation hardening. Heat treatment of metals: Annealing, normalising, solution treatment, hardening, tempering, precipitation hardening, recrystallisation annealing, stress relief Industrial alloys for structural applications – specifications and applications. Carbon steels, cast irons, special steels. Aluminium alloys. Die casting alloys (zinc and magnesium). High temperature alloys (nickel and titanium). Lab - Tensile Test (TT) Lab - Heat treatment of plain carbon-steels (HC) |
Teaching and Learning Strategies |
|
Teaching Method 1 - Synchronous teaching sessions weekly using Teams or Zoom to replace lectures, supplemented by provision of asynchronous self-study materials in Canvas or VITAL Description: Cover the under-pinning materials science and engineering concepts. Teaching Method 2 - Laboratory Work |
