Unit description Unit description
This unit provides an introduction to engineering materials and the relationship of mechanical, electrical and chemical properties to the structure of materials in an engineering context. Mechanical and electrical properties will be of particular focus and be the subject of lectures and practical giving an underpinning to an appreciation of engineering materials, at present and in their future development.

Learning Outcomes

On successful completion of this unit, you will be able to:

  • Students will understand the bases upon which materials are categorised as metals, ceramics, polymers or composites; electrical insulators, semiconductors or conductors; brittle or ductile materials.
  • Students will be able to account for the observed difference in conductivity between insulators, conductors and semiconductors. Students will understand the concept of majority charge carriers in semiconductors, and will thus be able to explain the difference between p-type and n-type semiconductors.
  • Students will have a good understanding of the behaviour of semiconductor diodes; and will hence be able to explain electron flow in a PNP or NPN transistor.
  • Students will be able to account for the observed features of a stress-strain curve, for ductile materials. Students will have knowledge of methods of increasing yield strength, including work hardening, solute strengthening and precipitation hardening. Steels will be used as a case study for each of these, leading to a familiarity with a dominant group of engineering materials.
  • Students will understand the role of different types of material in a composite. Students will be able to explain the function of a material dispersion in a matrix of a second material; and will be able to explain how this increases strength and also increases resistance to cracking.

General Assessment Information

Students must attend a minimum of 75% of workshops (/tutorials/pracs) to be eligible for the final exam.

Any student who misses 15 mins of a workshop will be deemed absent for that workshop.

Late assignments will incur at least a 50% mark penalty.

Only in-class assessments should be handwritten, in blue or black ink; all other assessments should be typed.

Diagrams should be drawn neatly and be presented in a legible manner. Any work that is deemed untidy may not be marked or marks may be deducted.

All numerical answers must have correct units and an appropriate number of trailing digits. A mark deduction will be made for answers without appropriate units and trailing digits.

All citations should be referenced appropriately.

Do not exceed the maximum length requirement. Any work that exceeds the specified word or page limit may not be marked or marks may be deducted.

Your name, your student number, your tutor’s name and your workshop class time should be clearly indicated on your assignment.  Assignments without this information may not be marked or marks may be deducted.

All submitted assignments should have the Faculty coversheet attached. Assignments without coversheets will not be marked. (http://web.science.mq.edu.au/intranet/lt/barcode/coversheet.php)

All submitted assignments should be submitted on iLearn via Turnitin.
