| Objective : | To give the students a basic understanding of construction materials, with emphasis on metals. The course aims to give fundamental knowledge of the components of materials and to explain how various processes may change the materials so desired properties appear. Likewise the basic tests of materials which describe the properties of the materials are covered. The student will know how to • determine certain properties of materials based on the description of its composition and its present state. • relate demands to a construction to fundamental parameters of materials. • determine basic heat treatment processes which may change the structure of the material and thus add desired properties or remove unwanted ones. • explain how materials may be changed by alloying other components and thereby add new properties including describing case hardening steel. • explain how the phase transformation for a certain alloy is calculated at various temperatures. • describe and use the iron carbon diagram. • carry out examination of materials via practical laboratory experiments and draw up detailed reports of the results of these experiments • use and understand concepts and terms used to describe the materials and their properties |
||
| Principal Content : | • Construction materials including the structure of materials and free body diagrams (the drawing up and use of these) • Detailed coverage of steel (Fe) and heat treatments • The iron carbon diagram and other phase diagrams • Methods of hardening • Various types of steel and their use in different constructions are covered. • Aluminium and cobber will be coved as representative of “non-iron metals”. • The most important tests of materials which describe the quality and usefulness of a material are covered. • The course has four laboratory experiments which are carried out in groups. The groups submit a report of each of the experiments. • Ten to twelve home assignments are submitted. |
||
| Teaching method : | Class room theory lectures and assignments as well as laboratory experiments (the latter carried out in small groups). | ||
| Type of examination : | Four hours written examination | ||
| External examiner : | External | ||
| Marking : | 7 step scale | ||
| Remarks : | All reports and a specified number of assignments must be submitted in order to sit for the examination. All aids are allowed at the examination with the exception of PC and mobile phone. |
