73444 - Materials For Industrial Product T

Course Unit Page

Academic Year 2018/2019

Learning outcomes

At the end of the Course, the student will achieve a basic knowledge for the comprehension of: (a) the basics related to the properties and use of materials; (b) the knowledge related to the chemical and physical properties of the main classes, subsets or particular materials of extensive use; (c) the mechanical behaviour of materials and the use of these properties for the sizing of an object.

Moreover, the student will achieve the basic technological knowledge for the production, the development, the characterization and the use of polymeric, metallic, vitreous and composite materials, in relation to their use, as well as the expertise even in terms of nomenclature, for an aware and correct use in design.

Course contents

Materials science. Classification of materials. Main metals, ceramics, polymers and composites used for the manufacturing of industrial products. General properties and their measurement. Mechanical properties: elastic properties, plastic deformation, fracture. Tests and Standards.

Structure. Crystalline and amorphous materials. Structural imperfections and their effects on the properties of crystalline solids. Microstructure; correlation between microstructure and properties of materials.

Mechanical properties of materials: elastic properties, plastic deformation, fracture. Tests and Standards for the measurement of mechanical properties.

Metals: Pure metals and metal alloys. Phase transformation in metal alloys. Steels and cast irons: the iron-carbon phase diagram. Mechanical properties as a function of microstructure and carbon content. Heat treatments of steels: tempering, annealing, normalizing. Copper and alloys; aluminium and alloys. Properties and manufacturing technologies of metals. Trace on corrosion of metals.

Ceramics: Traditional ceramics: bricks, tiles, cements, mortars, concretes; porcelain, glass. Advanced ceramics: oxides and carbides for high performances. Properties and manufacturing technologies of ceramics.

Polymers: Thermoplastic and thermosetting polymers. Structure and crystallinity of thermoplastic polymers. Thermal transitions in thermoplastic polymers: glass transition temperature and melting temperature. Mail technical polymers: structure, physical, thermal and mechanical properties, applications. Manufacturing technologies of polymers.

Composites: Matrix and dispersed phase. Main types and properties of matrix. Main types and properties of dispersed phase. Properties and manufacturing technologies of composites.

Teaching methods

Lectures. During the course, laboratory exercises on the measurement of physical and mechanical properties of materials will be carried out.

Assessment methods

Students will have to take two written tests:

  1. Written test on the physical and mechanical properties of materials (time available: 20 minutes). A maximum of 15 points can be obtained.
  2. "Ex tempore" drawing of a product (time available: 20 minutes). A maximum of 15 points can be obtained.

A global score of at least 18 points must be achieved to pass the exam.

Teaching tools

Practice exercises will be conducted about the measurement of the main physical and mechanical properties of materials.
