MECH105P Fundamentals of Materials

  • To present students with the major theoretical concepts associated with materials science, such as bonding, atomic and molecular structure, phase equilibria, crystallography, and dislocation theory, so that a strong understanding of the relationship between structure and properties in materials can be developed.
  • To define and understand the levels of structure inherent in materials, ranging from atomic and crystalline, through to micro and macro-structure.
  • To qualify and quantify the principal parameters (such as strength and toughness) used to characterise the mechanical behaviour of materials and to present and develop some of the principal methods and analyses associated with the measurement of mechanical behaviour of engineering materials when under load, both in the elastic and plastic regimes.
  • To develop an understanding of how properties can be optimised and changed (particularly strength) and how engineers can best work at the microstructural level to do this, particularly via manufacturing processes.
  • To survey and introduce principal manufacturing processes used for engineering materials within a context of the structure-property-processing triad that is central to materials science and engineering.
Code: MECH105P
Alt Codes: None
Title: Fundamentals of Materials
Level: 1
UCL Credits/ECTS: 0.5/7.5
Start: January
End: April
Taught by: Dr. Adam Wojcik (module coordinator)

Prerequisites

  • None

Method of Instruction

  • Traditional lectures for the majority of the theoretical content covering materials basics
  • Structured laboratory sessions (3 off) which combine tutorial/lecture content with hands-on observation and property characterization with brief write ups
  • As part of the MECH102P Mechanical Engineering Practical Skills I all first year students will have had a hands-on workshop practice sessions to cover major manufacturing processes used for principal engineering materials categories. This module will build on this experience as well as that gained in the scenarios from Design and Professional Skills ENGS102P
  • Materials & Manufacturing case study based project (group based) to aimed at understanding link between materials, manufacturing and design
  • On-line e-resource to support manufacturing project outlining techniques in use for common engineering materials
  • In third term, exam timetable permitting, 2 hours revision lectures

Assessment

  • Examination (70%)
  • Case study (15%)
  • Lab report, coursework and sheet (15%) (3 x 5)

 

To pass this module, students must:

  • Obtain an overall pass mark of 40% for all sections combined

Content

  • General: Basic definitions and fundamental properties important to the mechanical engineer
  • Bonding and solids
  • Alloys: including phase diagrams, analysis of the Pb-Sn, relationship between mechanical properties and the phase diagram
  • Introduction to steel
  • An introduction to polymers including glass

MECH105P Fundamentals of Materials

General Learning Outcomes:

  • A basic understanding of the level of structure within materials right down to the atomic level
